Pain Scrambler Therapy

Scrambler Therapy: New, Drug-Free Treatment For Chronic Neuropathic, Cancer Pain

A new pain management therapy plays games with your nerve fibers: It sends non-pain information via electrodes placed on the skin to nerve fibers that have been receiving pain messages, blocking the transmission of pain signals.

That’s how scrambler therapy works, using a machine by Calmare Therapeutics Inc. — no drugs and not invasive — for outpatient treatment of chronic pain.

Dr. Ricardo Taboada, an anesthesiologist specializing in pain management at the Hartford Hospital Pain Treatment Center, talks about nerve pain treatment on WFSB.

Beth Garrison, a physician’s assistant at the Hartford Hospital Pain Treatment Center, explains how the scrambler therapy works.

Q: What type of conditions can you effectively treat using scrambler therapy?
A: We can treat chemotherapy induced peripheral neuropathy and generalized neuropathies such as diabetic Complex Regional Pain Syndrome, and pain caused by damaged nerves.

Q: How does this therapy work to actually re-program pain?
A: Nerves pathways are how the body and the brain communicate. Calmare/Scrambler therapy actually reprograms transmission of the body’s pain signal through the nerve pathway so that the brain perceives it as reduced or no pain with the repetition of approximately 10 treatments.

The Calmare pain therapy device.

Q: Is this a one-time treatment or will it require a series of treatments?
A: If the patient responds to the initial treatment, and continues to have increased relief of pain by the third treatment, a series of 10 consecutive treatments is recommended with each treatment lasting 45-60 minutes.

Chronic Pain, Scrambler Therapy

Scrambler Therapy for the Management of Chronic Pain


Chronic pain is a widespread and debilitating condition, encountered by physicians in a variety of practice settings. Although many pharmacologic and behavioral strategies exist for the management of this condition, treatment is often unsatisfactory. Scrambler Therapy is a novel, non-invasive pain modifying technique that utilizes transcutaneous electrical stimulation of pain fibers with the intent of re-organizing maladaptive signaling pathways. This review was conducted to further evaluate what is known regarding the mechanisms and mechanics of Scrambler Therapy and to investigate the preliminary data pertaining to the efficacy of this treatment modality.


The PubMed/Medline, SCOPUS, EMBASE, and Google Scholar databases were searched for all articles published on Scrambler Therapy prior to November 2015. All case studies and clinical trials were evaluated and reported in a descriptive manner.


To date, 20 reports, of varying scientific quality, have been published regarding this device; all but one small study, published only as an abstract, provided results that appear positive.


The positive findings from preliminary studies with Scrambler Therapy support that this device provides benefit for patients with refractory pain syndromes. Larger, randomized studies are required to further evaluate the efficacy of this approach.


Chronic pain is estimated to affect 100 million people in the USA alone, resulting in up to $635 billion in medical expenses and lost productivity each year. It predisposes to psychiatric comorbidity, and its massive impact is highlighted by the fact that it is the most common cause of long-term disability in the USA.

In simplest terms, pain can be defined as a bodily sensation experienced during genuine, or perceived tissue injury. In the acute setting, this sensation can serve as a protective role by alerting an individual to avoid potentially harmful stimuli and to protect the body during healing. When pain fails to communicate biologically useful or accurate information, it is maladaptive and thereby becomes a disease state in its own right. It is generally agreed that pain becomes “chronic” when it persists beyond the expected period of tissue injury and healing. The specific duration of symptoms required to qualify for a diagnosis of chronic pain is debatable but generally is considered to be in the range of 3 to 6 months.

The perception of noxious stimuli originates from nociceptors of the peripheral nervous system. Nociceptors recognize stimuli in the form of thermal, mechanical, or chemical inputs. The stimulation leads to activation of primary sensory nerve fibers that transmit this information to the central nervous system, via a complex network of interneurons housed predominantly in the dorsal root ganglia, posterior horn of the spinal cord, brain stem, and thalamus. Ultimately, signals reach the forebrain for interpretation of the sensory experience. There are multiple mechanisms that underlie the dysregulation of this system in chronic pain. In the setting of injury, for example, inflammatory changes in the biochemical milieu surrounding peripheral nerves can result in hypersensitization of nociceptors, such that pain signals are communicated in the absence of appropriate stimuli. Neurons surrounding damaged tissue have even shown the ability to develop spontaneous discharges that communicate pain information in the absence of external input. Similarly, spinal cord neurons in the central nervous system exposed to repetitive pain stimuli may undergo changes that result in the transmission of action potentials with a reduced threshold of synaptic input.

Currently, several treatment modalities exist for the management of chronic pain, including physical therapy, pharmacologic therapy, behavioral medicine, neuromodulation, minimally-invasive interventions, and surgery. Unfortunately, the heterogeneous nature of chronic pain syndromes and the lack of a functional understanding of chronic pain contribute to the absence of a clearly identifiable, appropriate management strategy for many patients. Nonetheless, pharmacologic measures are commonly prescribed as a component of chronic pain management. With many medications available, such as non-steroidal anti-inflammatory agents, anticonvulsants, antidepressants, and opioids, it is exceedingly common for patients to use multiple agents to try to achieve reasonable pain control.

Recognizing the limitations and hazards of polypharmacy, increasing emphasis has been placed on the non-pharmacologic options for management of persistent pain. A strategy combining psychological and physical medicine approaches can provide significant benefit for many patients . Neuromodulatory techniques, particularly since the commercial availability of wearable transcutaneous electrical nerve stimulation (TENS) units in the mid-1970s, have gained popularity as an adjunct to both pharmacological and non-pharmacologic pain management. While promising in theory, the scientific data supporting such methods remain limited, without consistently-shown benefit, underscoring the need for novel therapeutic options.

The aim of this paper is to review what is known about the mechanism of a relatively new neuromodulatory approach, Scrambler Therapy, and discuss the trials and clinical experience, published to date, regarding its use.


Reports regarding Scrambler Therapy were identified by a combination of a database search, communication with investigators, and reviewing bibliographies of previously published manuscripts (Fig. 1). Several databases were utilized in the literature search, including PubMed/Medline, SCOPUS, EMBASE, and Google Scholar. Search terms including “Scrambler Therapy” and “Calmare” were used to identify all articles published prior to November 1, 2015. The search was refined with the use of Boolean terminology, specifically “Scrambler Therapy OR Calmare,” which yielded the largest number of articles. Results of these studies were reviewed and reported with an analytic intent that was primarily descriptive.

Chronic Pain, Scrambler Therapy

Scrambler Therapy development and mechanisms

Giuseppe Marineo, a biophysicist who developed an interest in treating chronic pain, developed Scrambler Therapy and conducted basic and applied research related to its use. Marineo claims that chronic pain is the consequence of a phenomenon produced by the persistence in time of pain pathway activation, a typical condition of neuropathies. This process results in a loss of the linearity in the cause–effect relation that characterizes the physiological acute pain (which is protective) and creates a new type of nonlinear behavior of the pain system, that tends to self-sustain an anomalous response to painful and non-painful stimuli. Marineo proposes that the entire chronic pain process can be controlled by intervening on the afferent information aspects of pain, the variable that characterizes and mainly regulates every activity of the nervous system and represents its natural cybernetic expression. In short, Scrambler Therapy’s active principle is information control that manipulates the modulation or re-modulation of the pain system, and its physiological or pathological responses, in line with plastic properties of the nervous system. More specifically, a Scrambler Therapy unit is composed of five electrical stimulation channels that, through the surface receptors of C fibers, replace the endogenous pain information with a synthetic one of “non-pain” or “normal-self” that travels through the same pain pathways to the brain. Through plasticity within brain networks mediating the perception of pain, a series of treatments “retrain” the brain so that the area of concern is no longer considered painful. Marineo proposes that his functioning principle, like its neurophysiological target that uses receptors of C fibers, replaces the chronic pain information, rather than attempting to block its ascending path. An in-depth analysis of these differences are described in the International Patent PCT/IT2007/000647 and U.S. Patent No. 8,380,317.

Scrambler Therapy has also drawn comparisons to spinal cord stimulation, which is another interventional technique that has been utilized in the treatment of refractory chronic pain. Spinal cord stimulation has been proven to be efficacious in a diverse array of pain syndromes, including refractory angina, failed back syndrome, and complex regional pain syndrome (CRPS), with the ability to reduce pain intensity in some cases by over 50 %. The drawback of this approach has largely been its invasiveness and cost.

What is the normal course of Scrambler Therapy?

Several authors of the present manuscript utilize Scrambler Therapy in clinical practice. Information in the following section is derived from their experience in treating hundreds of patients for a variety of pain syndromes. A patient treated with Scrambler Therapy has the area of pain identified and then has electrodes placed on the normal tissue around the painful site. The electrodes are not placed at the site of actual pain, but, instead, placed at a nearby location of preserved sensation. The dermatomal location is to feed this “non-pain” confusing information into the regular nervous circuit using peripheral nerves, rather than accessing the spinal cord. The intensity of stimulation is adjusted according to patient comfort and, if the placement is correct, the pain will usually be replaced by the Scrambler device sensation, which is often described as “pleasant, vibratory, and/or humming”. Up to the full set of five sets of electrodes can be used to treat the area(s) of pain. The device is allowed to run for a total of 30–45 min once the electrodes have been optimally positioned and stimulation intensity correctly regulated. After a session’s completion, patients may report a soothing sensation and note that the pain has been markedly reduced or has disappeared entirely.

The benefit from Scrambler Therapy, after the first treatment, generally lasts for a relatively short period of time. When treatment is reinitiated the next day, the same process happens, but the benefit generally lasts longer, e.g., for a few hours. In most cases, if the treatment has been given properly, with each treatment session, the non-pain (or meaningful relief) timeframe is extended. The duration of posttreatment relief classically lengthens with continued treatments until, ideally, the benefit is maintained throughout the entire day. Usually, Scrambler Therapy is given for a total of ten treatment sessions on consecutive weekdays, if feasible, although some patients need fewer and some patients need more treatments. Pain relief can be expected to persist for weeks to months after treatment is stopped. When patients relapse, booster sessions can be administered. It may only take one or two booster sessions to re-establish the benefit that previously occurred, and this benefit may last for a substantial period of time (oftentimes months or longer).

Scrambler Therapy is an operator-dependent methodology. Treatment success is highly dependent on the ability of the operator to eliminate pain during each single treatment without any significant patient discomfort. Failure to completely resolve pain in a treated area (or have a Visual Analog Score < =1) during each treatment session may lead to less satisfactory results. Experience has confirmed that more expert operators can eliminate pain during Scrambler Therapy when less experienced ones have failed. This may explain, in part, why data coming from different publications are relatively heterogeneous.

Scrambler Therapy clinical trials

To date, 20 trials/reports of Scrambler Therapy are available for review (View Table). Eighteen have been published as manuscripts and two only as abstracts. One is a retrospective study, five deal with clinical practice experiences, 11 are prospective single-arm clinical trials, one is a randomized open-label controlled trial, and two are randomized, blinded, placebo-controlled trials.

View Table Here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4973603/table/T1/?report=objectonly

The first trial was authored by the Scrambler Therapy developer, Marineo, in 2003 and reported the results of the treatment of 11 patients with cancer-associated, drug-resistant, visceral pain. This manuscript noted that pain was quickly and markedly reduced in the studied patients, with 9 of 11 patients stopping the use of pharmacologic pain therapy altogether after the first five sessions, without any associated side effects. Pain scores were reported to have decreased from approximately 8.5 out of 10, at study initiation, to approximately 0.5 out of 10, after 10 treatments. No adverse effects were reported.

A second trial was published in 2005, with Marineo as a co-author. A total of 226 patients with neuropathic pain were treated, including patients with failed back surgery, brachial plexus neuropathy, and other chronic pain conditions. This trial, while also uncontrolled, was impressively large and reported that 80 % of subjects had at least a 50 % pain reduction and 10 % experienced a reduction of 25–49 %. Ten percent (10 %) had no appreciable response. No adverse effects were reported.

Additional groups became involved in the clinical evaluation of this therapy with the publication in 2010 of the first study that did not include Marineo as a co-author. This was a pilot trial in 16 evaluable patients with chronic chemotherapy-induced peripheral neuropathy, conducted at Virginia Commonwealth University. The findings from this study were in line with the success seen with the previously reported trials. After ten treatments, the average reported pain score dropped nearly 60 %, with four patients achieving complete resolution of pain. Patients with recurrent pain successfully retreated with 1–3 subsequent treatments.

The next trial, currently only available as an abstract, involved ten patients with failed back surgery treated by an anesthesiology-trained pain physician. While it only noted a 28 % mean pain reduction, there were patients on this trial who had substantial relief after multiple other therapies had failed to provide benefit. The author of this abstract, a coauthor on the present manuscript, notes that there are three reasons why his success rate might have been relatively low: (1) he had limited operator experience; (2) he included study subjects with multifactorial intractable pain despite intensive polypharmacy; and (3) treatment while adjuvant anticonvulsants were continued. Empiric observations have suggested less than optimal outcomes if these medications are not discontinued prior to treatment.

Marineo and colleagues published the first randomized, controlled trial in 2011, which involved 52 patients with chronic neuropathic pain related to postsurgical causes, post-herpetic neuralgia, or spinal cord stenosis. Scrambler Therapy was compared to a control arm that utilized standard pharmacologic guideline-based recommendations, including frequent phone calls to modify analgesics. The pain reduction, after finishing 10 days of treatment, was 28 % in the control group (pain scores dropped from 8.0 to 5.8 out of 10) compared to a 91 % reduction with the Scrambler group (pain scores dropped from 8.1 to 0.7; p < 0.0001). Pain scores in the control arm were 5.7 and 5.9 at 2 and 3 months, respectively, as opposed to 1.4 and 2.0 in the Scrambler group (p < 0.0001). Analgesic consumption, including opioids, antidepressants, and anticonvulsants, decreased by 72 % in the Scrambler group. Allodynia also was reduced in the Scrambler patients, from 77 % at baseline to 15 % at 3 months. The benefit was obtained relatively equally amongst patients of all of the three diagnostic categories.

The sixth trial involved 82 (73 evaluable) prospectively-treated patients, about half of whom had cancer-related pain. Mean pain scores reduced from 6.2/10 before to 1.6/10 at the end of treatment and were 2.9/10 1 month after treatment was finished. Similar results were seen in patients with and without cancer. When patients were asked whether they would repeat this treatment, 97 % (71/73) responded affirmatively.

The seventh trial involved a cohort of eight patients treated with Scrambler Therapy for chronic low back pain. Patients were treated for six consecutive days; pain scores were recorded prior to initiation of treatment and after each session. The mean pain score was 8.12/10 at baseline, dropping to 6.93/10 after the first treatment. The mean pain score dropped to 3.63/10 in day 6. The group also recorded the Oswestry Disability Index (ODI) and found that mean score dropped from 49.88/100 to 18.44/100 by the end of the study, signifying an average drop from severe to minimal disability.

The eighth investigation was a prospective trial that reported on a series of 39 patients with cancer pain syndromes, including 33 with chemotherapy-induced peripheral neuropathy. Scrambler Therapy was associated with significant positive changes from baseline for a large number of outcomes, including degree of pain, interference with normal activities, and sensory neuropathy symptoms. The benefit persisted up to 3 months.

A small prospective trial published in 2013 involved 10 patients with post-herpetic neuralgia and included some data previously reported in another publication. The work reported a 95 % reduction in pain scores at 1 month, with sustained benefit observed at 2 and 3 month follow-up times.

In 2014, a prospective pilot trial experience was published, involving the treatment of 37 patients with chemotherapy-induced peripheral neuropathy, noting about a 50 % reduction in pain, tingling, and numbness. The increase in Scrambler benefit over the course of the trial suggested that, despite initial operator training in the administration of Scrambler Therapy, a learning curve was evident in this trial. The last 25 % of patients entered on this clinical trial did substantially better than did the first 25 % of patients, likely a reflection of improved technique afforded by greater experience.

The first attempt to compare Scrambler Therapy to a sham control was presented as an abstract at the 2013 Annual Meeting of the American Society of Clinical Oncology, involving 14 patients who were treated in a randomized, controlled, and double-blind manner. Results from this study have not been published as a manuscript. While the authors did note that the sham treatment from this particular trial was believable, in that the patients could not more often detect which of the two procedures was the true one, the authors did not observe any real improvements in neuropathy in the patients treated with the sham procedure versus Scrambler Therapy. This may well have been because this group had little experience with the technique prior to conducting their study. This finding fits with above-noted work that observed that there is a learning curve for the appropriate application of this therapy for treating chemotherapy neuropathy, which likely also applies to the treatment of other conditions. Additionally, the results of this trial support that there was not much of a placebo effect in this trial, as no benefit was noted in either trial arm. Paradoxically, this would support the argument that the positive results reported in other chemotherapy neuropathy Scrambler Therapy trials are not just ascribable to a placebo effect.

In 2015, a single-blind, sham-controlled, randomized clinical trial involving 30 patients with low back pain was reported from Virginia Commonwealth University. These authors noted significant decreases in the Brief Pain Inventory (BPI) back pain scores and pain interference scores (P ≤ 0.05). They also noted improvements in pain sensitivity, as measured by participants’ thresholds for pain in the initially painful area. Of note, the group randomizedtoScramblerTherapyhadsubstantialdecreasesin10 serum messenger RNAs (mRNAs) associated with nerve pain such as nerve growth factor (NGF) and glial derived nerve factor (GDNF), compared to no decreases in the sham group, understanding that these mRNAs have not yet been established as correlates for pain.

More recently, two subsequent single-arm prospective trials have been published which support therapeutic benefit. A pilot study was reported from an Italian hospital, evaluating outcomes of Scrambler Therapy in 25 patients with pain related to bony and visceral metastases. Each patient was scheduled for 10 daily sessions of treatment, and pain outcomes were measured by the use of a numeric pain scale. All patients were reported to have experienced at least a 50 % decrease in pain scores, with a mean pain score of 8.4 at baseline dropping to 2.9 after completion of the treatment course. The average duration of “pain control” (defined as >50 % reduction from baseline pain score) was 7.7 +/− 5.3 weeks. Sleep performance was also noted to improve significantly for the cohort. In Korea, Lee et al. performed an open-label, single-arm, exploratory study involving 20 patients with CIPN, metastatic bone pain, and postsurgical neuropathic pain. Pain scores decreased significantly, as did consumption of rescue opioid medication.

Clinical Practice Experiences

Two case series, published in 2013, each included three patients with cancer pain or post-herpetic pain. Both of these reports came from different authors and both reported positive benefits in the patients who were treated.

Sparadeo et al. reported their clinical practice experience regarding 91 of their initial 173 patients, representing all of those for whom they had collected data. These patients had a variety of pain syndromes, including CRPS, spine pain, neuralgias (such as post-herpetic or post-chemotherapy), and multi-focal pain problems. As part of their practice, with these 91 patients, they collected visual pain scores before and after each treatment for all of them and BPI questionnaires, in a subset of them, prior to treatment initiation and at 3- and 6-month follow-up times. The mean pain score prior to the first treatment was 7.2/10; it was 3.0/10 on the 10th day, prior to that day’s treatment. Relatively similar results were seen for the different pain syndromes. BPI scores at 3 to 6 months of follow-up were reported to be improved by more than 50 %.

In a second manuscript, Sparadeo and D’Amato analyzed the pre- and posttreatment data of 95 individuals (some of whom had been reported in the previous publication) entering their Scrambler Therapy program for treatment of chronic neuropathic pain, divided into two groups: CRPS and chronic spine-based pain. All patients were weaned from opioids and anticonvulsants being used for pain control. The data analysis revealed that 70 % of the entire sample was still reporting significant improvement 3 to 6 months following treatment. The two studied groups had similar levels of pain and degrees of lifestyle impact. Additionally, the 3–6-month successes were similar in the two treatment groups.

Another clinical practice experience report involved 147 patients treated at two United States military sites and one South Korean site. They noted that 38 % of patients had at least a 50 % pain reduction that lasted for more than a month.

Retrospective Study

Lastly, one retrospective report on Scrambler Therapy, involving 201 patients across multiple centers, was recently reported. Patients were treated for a variety of chronic pain syndromes; the most common indications included post-herpetic neuralgia, chronic low back pain, and polyneuropathy/ peripheral neuropathy. Patients were treated for a mean number of 10 sessions, with 39 patients experiencing complete resolution of pain symptoms sooner than this. The mean pain scores were 7.41 prior to treatment and 1.6 following treatment (P < 0.0001). Achieving a pain score of 0 during treatment was observed to associate with the durability of pain control, prompting the authors to advocate for a complete response as a target of therapy sessions.

Does Scrambler Therapy actually work?

Arguments against Scrambler Therapy certainly exist, with critics attributing much of the benefit to a placebo effect. Some of the positive endorsements in social media and on the Internet are only anecdotal. Additionally, the developer of Scrambler Therapy participated in the initial clinical trials, and this could be perceived as a potential conflict of interest even though it is scientifically desirable and logical to expect the device inventor to report the first set of results. Additionally, some of the reports claim that there is a phenomenal benefit that lasts for a long time, which sounds too good to be true. Lastly, there are no large, placebo-controlled, double-blinded clinical trials to estimate the effectiveness of Scrambler Therapy.

On the other hand, while some reports involved the inventor of the Scrambler device, these positive findings have been independently replicated by diverse groups in nearly all of the reported studies, involving over 900 patients in total. In some cases, the benefit achieved has been substantial, with some patients achieving complete pain resolution and substantially reduced dependence on pharmacologic therapy. There has been only one report of a negative experience. This was from one small, placebo-controlled trial in patients with chemotherapy-induced peripheral neuropathy. This was published only as an abstract, did not show much of a reduction in either study arm (arguing against a placebo effect), and was produced by a group that did not have much experience using Scrambler Therapy. This raises concerns regarding the validity of this trial, as data have supported that there is an extended learning curve with the provision of Scrambler Therapy, particularly for chemotherapy-induced neuropathy . At the same time, it must be noted that although this is the only negative trial published on Scrambler Therapy, the possibility of publication bias cannot be excluded. Negative experiences may not be put into publication form for various reasons, and so the currently available literature may be overestimating the positive experience with this technology.

The downsides of trying Scrambler Therapy

The downsides of trying Scrambler Therapy for chronic pain primarily relate to the time and expense associated with its administration, in addition to noting that many proposed treatments for chronic pain have not withstood the rigors of time and/or well conducted randomized trials. Additionally, the therapy is not yet widely available and some insurance companies will not pay for it due to lack of evidence or will reimburse it at very low rates. However, some insurance companies are covering this treatment as they have started to note the benefit of this therapy in allowing patients to return to work, with decreased use of medications and procedures. Scrambler Therapy relies on practitioner skill and familiarity with technique, which can influence outcomes, as has been noted in the literature. This might impede rapid integration into practice, especially in the absence of formalized training.

Additional Research

Additional work is needed to better understand the mechanism of Scrambler Therapy and to conduct larger randomized clinical trials investigating the efficacy of Scrambler Therapy in a number of chronic pain states. A large, multi-center, randomized, sham-controlled double-blinded trial, involving patients with a variety of chronic pain syndromes, would strengthen the conclusions from initial studies. The data compiled, to date, support the feasibility and value of such an undertaking. Multiple other research lines of investigation would be helpful for further defining the worth of Scrambler Therapy. Such work could better evaluate the types of patients who benefit, the best means for teaching operators, and the compatibility of this approach with other treatment approaches. For example, as indicated above, there are recommendations to titrate down and discontinue anticonvulsant medications prescribed for pain management prior to initiating Scrambler Therapy, based on the theory and empiric clinical experience that these agents may interfere with the therapeutic mechanisms involved. Whether this is truly necessary could be a focus of future research. To better define the mechanisms of action, studies of brain reactivity (functional MRI) and peripheral nerve function (changes in epidermal nerve fiber density or electrophysiological measures or quantitative sensory nerve testing) would be useful.

Breaking Away From Pain With the Help of ‘The Scrambler’

Participating in a clinical trial gave Karen Safranek a solution to her decade-long struggle with peripheral neuropathy 

Karen Safranek didn’t take a worry-free step for 10 years. Severe peripheral neuropathy — a side effect of breast cancer treatment she received in 2002 — left her with constant burning, tingling, numbness, and pain in both her feet.

Over time, Karen tried dozens of treatments to rid herself of the discomfort. Nothing worked. So in 2012 when she found out about a clinical research trial available at Mayo Clinic for people who had peripheral neuropathy after chemotherapy, she was interested, but not optimistic.

“I tried so many things. Anything a doctor recommended or heard about, or anything I heard about, I’d give it a try if I could,” Karen says. “But years past, and the pain didn’t get any better. By 2011, life was not good. I was analyzing my house to figure out where we could put a wheelchair ramp. At that time, I thought it wouldn’t be much longer before I couldn’t walk anymore.”

This new treatment was different. With MC-5A Calmare Therapy, often called “the scrambler” for short, Karen noticed improvement following the first session. After completing a series of treatments, she was pain-free for the first time in more than a decade. Through her participation in the clinical trial and occasional follow-up treatments at Mayo Clinic, Karen has been able to leave peripheral neuropathy behind and reclaim her life.

Battling pervasive pain

Karen began to notice symptoms of peripheral neuropathy shortly after she started receiving chemotherapy. By the end of her treatments, her breast cancer was gone, but she had constant shooting pain and numbness in her feet and legs that left her weak and unable to maintain her balance.

Peripheral neuropathy is a common side effect of some chemotherapy drugs. For many people, the condition fades away after treatment is over. But for some, like Karen, it can last long after other chemo side effects are gone and can have a significant impact on day-to-day life. The effect on Karen’s life was overwhelming.

“It hurt if I was sitting, walking or standing,” she says. “Blankets hurt my legs. I wasn’t getting a good night’s sleep. Going back to work wasn’t an option. In time, it got so bad that whenever I went somewhere, I would analyze where I had to park my car and how far it was to get to the building. If there wasn’t a spot close enough for me to walk the distance to and from my car, I would just go home.”

Retraining the brain

Traditionally, chronic peripheral neuropathy has been challenging to successfully treat. Like many others who have this debilitating disorder, Karen tried everything she and her doctors could think of to relieve her pain. But still, she suffered. Then in December 2013, Karen learned of the clinical trial at Mayo Clinic that would change everything for her.

Peripheral neuropathy happens as a result of nerve damage. The damaged nerves send aberrant signals to the brain, causing pain and the other symptoms of peripheral neuropathy. During her treatment sessions as a participant in the research study, the damaged nerves in Karen’s feet were connected by electrodes to the scrambler. The device sent painless electrical signals to the damaged nerves, and the nerves relayed those signals to the brain. The new signals broke the pain cycle by retraining Karen’s brain to understand that it was not really experiencing pain.

Reclaiming her life

Although the scrambler does not ease symptoms of peripheral neuropathy in all cases, Karen’s response was dramatic.

“I was tremendously better after just one treatment,” she says. “My feet and legs felt light and pain-free. Previously, I had felt as though they were very heavy to lift and walking was comparable to wearing cement shoes. After the treatment, I could walk really fast. I could take the stairs. I could even run.”

After a total of 10 treatment sessions in January 2013, Karen no longer had any symptoms. The effects of the treatment were not permanent, however. She returned to Mayo Clinic for additional scrambler treatment nine months after her first sessions and again eight months after that.

Even though she knows she’ll likely need follow-up care over the long-term to keep peripheral neuropathy at bay, Karen is enthusiastic about the difference the treatment has made for her.

“Before this, I wasn’t able to do some of the smallest things. I couldn’t go grocery shopping alone. If I reached up to take an item off the shelf, I’d lose my balance and tip over. I couldn’t walk on uneven ground because I couldn’t feel my feet. I’d just fall down,” she says. “Being able to participate in this clinical trial at Mayo Clinic with the scrambler, it brought my life back to me. It’s a miracle. It really is.”

Optimizing Neuropathic Pain Relief With Scrambler Therapy

Minimizing the incidence of medication dependence in patients with chronic neuropathic pain (NP) poses significant difficulty for treating physicians. A recent increase in accidental deaths related to prescription opioid use has boosted the investigation of novel techniques for the treatment of chronic pain.1 In addition to the risk of opioid dependence, chronic pain patients suffer from a wide range of secondary medical conditions, including mental health difficulties and physical disabilities.2 Given the need for simultaneous treatment for chronic pain and associated comorbid conditions, pharmacological interventions alone are often inadequate when managing complex chronic NP syndromes.3

Efforts to minimize risk of harm to chronic NP patients and their families prompted the development of noninvasive and nonpharmacological interventions.4 This trend toward more comprehensive and personalized standards of care will likely aid in appropriately relieving pain in patients suffering from NP syndromes, and will allow physicians to more directly address any associated medical conditions.

Among the novel alternative treatments for chronic NP syndromes is a patient-specific neurostimulative technique called scrambler therapy (ST). Scrambler therapy uses a noninvasive transcutaneous electrostimulation device that has shown promise for providers and patients seeking alternatives to traditional pharmacological pain relief techniques. Scrambler therapy works by introducing a pleasant sensation that acts as a distraction by sending a new message to nerve fibers that were used to receiving pain signals.

This retrospective review aims to shed light on the nature and extent of pain relief experienced during and across stimulation visits. The authors hypothesize that ST will reduce pain ratings for patients with a variety of chronic NP syndromes across and within stimulation visits.

Scrambler Therapy Promises Sustained Relief From Chronic Pain

Scrambler therapy was designed primarily as a method for treatingcancer-related pain syndromes like chronic chemotherapy-induced peripheral neuropathy (CIPN).5Researchers explored the application of ST as a way of alleviating pain in cancer patients when metastases in the epidural space prevented use of nerve blocks and opioids from offering sufficient relief, and when adverse side effects prohibited achievement of adequate pain relief.

A preliminary case series reported findings of effective pain relief for 3 patients who were affected by severe cancer pain.6 In a separate pilot study of patients with CIPN, ST reduced pain scores by 53%, tingling by 44%, and numbness by 37%.7 This same study indicated that pain-relieving benefits of ST were sustained through 10 weeks of follow-up care. In another study, Coyne and colleagues measured changes in pain level on the Numerical Pain Rating Scale (NPRS)—a pain rating scale with 0 corresponding to “no pain” and 10 corresponding to “worst pain imaginable.” They found that when cancer patients were allowed to mark decimal points, pain ratings decreased from 6.6 before treatment to 4.6 over 3 months.8

Initial success in alleviating cancer-related NP syndromes allowed ST to emerge as a potentially successful treatment for a broader category of NP syndromes, including postherpetic neuralgia, low back pain, polyneuropathy, and peripheral neuropathy.4 Marineo et al aimed to directly compare ST to guideline-based drug therapy for patients grouped into a larger category of poly- or mono-radiculopathy.4 This randomized pilot study provided preliminary evidence that the neurostimulative technique may successfully alleviate pain better than pharmacology, reporting a mean rate of pain reduction of 91% in the first month of ST.As personalized noninvasive treatments develop, growing evidence has been presented in favor of these devices to successfully alleviate chronic pain over time.7,9

In a recent examination of ST, this method produced a reduction in chronic pain from a pretreatment score of 7.41 to 1.60 pain score (based on NPRS) following 10 sessions of treatment.9 This comprehensive study also divided patients into several broad categories of chronic pain, ultimately suggesting that the ST’s efficacy may be dependent on pain type. While promising, these pain rates and time frames for pain relief in patients with general chronic pain syndromes differed from those reported in the studies examining ST in a population of CIPN patients.7,8

Reports of inconsistent rates and time spans for achieving pain reduction reflected an urgent need for further research concerning the mechanism and efficacy of ST. Of particular interest to researchers was identifying the length of time necessary for ST to achieve consistent, maximal benefit. Additional considerations in pursuing this research included whether specific types of NP syndromes, pain locations, and severity levels were better suited to favorable treatment response with ST.

This retrospective review was conceived to bolster the current evidence basis by examining the efficacy of repeated ST treatments over time through a lens of specific NP conditions.

Pain Relief From ST Assessed Across Multiple Conditions

A retrospective chart review was conducted among 25 patients who received ST as administered by a neurologist between 2014 and 2015 at an outpatient pain management clinic in Hopewell, New Jersey.10 Basic demographic factors, including age and sex, were gathered. Pain-related data was also collected for pain diagnosis or classification, areas of pain, and descriptive characteristics of reported pain. Concomitant medications and pre- and post-stimulation blood pressure were noted.

Stimulation treatment details were gathered, including side effects, frequency (volume) of stimulation, location of treatment, dates of treatment, and number of treatments. Institutional review board approval was obtained for this chart review,10 which met compliance standards and ethical guidelines set by the participating institution.

Chronic Pain Update

New device offers relief

Chronic pain is a common problem that can take a significant toll on your mental and physical health. There arc various of causes of chronic pain, and a variety of strategies may be employed to manage pain or treat the cause.

These methods can be effective for some, particularly when combined into a comprehensive pain rehabilitation plan. However, it’s clear that addition-al therapy options are sorely needed.

Thankfully, one new therapy can be added to the list — at least for neuro-pathic pain tha€s caused by faulty nerve signals. Called scrambler therapy, it’s a novel form of electrical stimulation ap-plied to the skin. It involves sending scrambled electrical signals along nerve pathways to the brain in an attempt to retrain the brain to perceive the area of pain as normal, not painful.

Retrain the brain

With many types of chronic pain, normal nerve signals go haywire. There are multiple ways this can occur. Nerve endings may become damaged. Sensa-tions of pain may continue to be trans-mitted by nerve endings even after healing ofnearby tissues. Or nerve end-ings or nerves in the spinal cord may become somehow sensitized so that

even normal sensations —

such as

touch — cause the feeling of pain.

With the pain scrambler, the goal is to hijack the nerve pathways sending pain signals, and override the pain sig-nals with normal, nonpain signals. It’s believed that this can retrain the brain to recognize the area of pain as normal, not painful.

Wires from the pain scrambler machine run to electrode pads attached to points on the skin that are near, but not on, the site of pain. The scrambler electrodes are turned on, and the in-

tensity of the electrical signal is gradu-ally increased to where you can feel sensations, but not pain. The treatment continues for about 30 to 45 minutes. When successful, the pain is at some point replaced by the scrambler device sensation, which is Often described as a buzzing sensation. It’s believed that best results occur when the pain is com-pletely replaced by the buzzing sensa-lion during every scrambler session.

If the treatment is successful, the pain is usually greatly diminished or gone when the machine is shut off. This benefit may only last a few minutes to a few hours after the first session. But the process is repeated daily, and the post-treatment period Of benefit usu-ally gets longer after each session until the pain relief lasts for a day or more.

Ten sessions is the standard number needed, but it can be more or less than 10, depending on how things go.

Pain relief can persist for weeks to months after treatment is stopped. When pain returns, sometimes as few as one or two booster sessions can restore the benefit, and that benefit may last months or longer.

Mayo Clinic doctors are optimistic about the pain scrambler. Based on re-search and their own experience treating people at Mayo Clinic with the device,

it appears that the scrambler therapy can have good to sometimes dramatic results in people with select types of chronic pain who have reached the end of the line in terms of options. Importantly, it’s

generally well-tolerated.

The device appears to work best for chronic pain that is fairly isolated to one area, and due to faulty nerve signals, For example, research has shown good re-sults for conditions such as nerve pain (peripheral neuropathy) caused by che-motherapy, pain after a bout of shingles (postherpetic neuralgia), cancer-related pain, low back pain and numerous other pain syndromes.

It’s less clear if any benefit could be derived for Other common causes of chronic pain, such as osteoarthritis, fi-bromyalgia, irritable bowel syndrome or headache.

The downsides

Although the pain scrambler appears to reduce pain in most people, not everyone will benefit, and some people see only a modest benefit. In addition, i€s not widely available in the U.S.

Another potential downside is that it

(lakes a skilled operator for best resultsD that learning curve may skew research results or make it difficult for the device to be more widely adopted. -71

Scrambler therapy is a form of electrical stimulation applied to the skin for neuropathic pain that’s caused by faulty nerve signals.

Nerve Scrambler Therapy lessens pain for warfighters, Tricare patients

In reality, NST is one of the 79th Medical Wing’s most cutting edge methods for managing chronic and debilitative nerve pain that impacts warfighters’ job performance and long-term quality of life.

“Like many civilians, military patients sometimes experience nerve pain after they’ve healed from injuries or have been treated for diseases,” said Lt. Col. Candy Wilson, 779th Medical Group nurse scientist and NST practitioner. “NST has proven to be a viable alternative to opioids for reducing or eliminating this kind of pain.”

Nerve pain that indicates no underlying injury or disease, technically known as peripheral neuropathic pain, can affect patients who undergo chemotherapy or suffer from diabetic or sciatica pain, drug/toxin exposure, infections stemming from surgical complications or incidents of trauma.

“A common case we treat with NST is a condition found among some wounded warriors known as phantom limb pain,” said Wilson.
Phantom limb pain is a condition in which an amputee experiences pain sensation from the part of the body that was removed.

Wilson and her nursing colleagues at the 779th MDG’s Acupuncture and Integrative Medicine Center administer NST using a Calmare machine. Calmare is the name of the manufacturer and it means “to soothe” in Italian.

NST involves sending a low voltage current of electrical stimulation through two electrode pads placed on the skin of the patient. One pad is placed on a part of the body inches away from the source of a nerve pain; the other pad is placed on a part of the body not affected by pain.

According to the Calmare Therapeutics Company’s official website, the stimulation scrambles the pain nerve signals to the brain. A “no pain” signal to the brain replaces a pain signal. Cleared by the Food and Drug Administration, the Calmare machine has been used successfully in Europe for the past 15 years and in the U.S. for the past few years. The website reports the treatment is painless, non-invasive and patients experience no adverse side effects.

“In effect, NST means we’re able to re-train the brain for reducing or eliminating pain,” Wilson said. “Recurring treatments over a certain amount of time result in prolonged pain relief for the patient.”

Patients needing treatment at Acupuncture and Integrative Medicine Center require a referral from their primary care provider. Then, their treatment is determined by one of the Acupuncture and Integrative Medicine Center’s physician acupuncturists.

“Referrals are necessary to ensure we are providing the appropriate and most effective treatment for our warfighters and other patient beneficiaries,” said 1st Lt. Folake Niniola, 779th MDG registered nurse. “Because of our thorough screening process, we’ve been very successful with this therapy and there have been no known or reported side effects or injuries from the use of this machine.”

Because of the Nerve Scrambler Therapy’s ability to reduce patients’ pain without side effects, the 79th MDW exemplifies the Zero Harm tenet of Air Force Medical Service’s patient care philosophy.
