Noninvasive Neuromodulation Methods in the Treatment of Chronic PainRichard Rokyta1 and Jitka Fricova2[1] Charles University in Prague, Third Faculty of Medicine, Department of Normal, Pathological and Clinical Physiology, Prague, Czech Republic[2] Charles University in Prague, First Faculty of Medicine and General Faculty Hospital, Department of Anaesthesiology, Resuscitation and Intensive Care, Pain Management Center, Prague, Czech Republic1. Recent developments by a cluster of medical technology organisations suggest that long-awaited effective treatments for neuropathic pain may finally be on the horizon. A large patient population has made neuropathic pain a major target for pharmaceutical companies.  However, the limited therapeutic window of current indicated drug treatments has prevented effective management of the disease.
Step forward neuromodulation, or the controlled stimulation of specific neurons via precise electrical impulses in order to produce a defined biological response. The lack of effective drug treatment – and paucity of innovative pipeline therapeutics – has also forced pharmaceutical companies to look towards neuromodulation as an alternative treatment approach. On a broader note neuromodulation has huge potential to meet often entrenched unmet needs of other complex pathologies such as spinal cord injury, metabolic diseases, autoimmune disorders and respiratory conditions.  However, much more applied research is needed in this field, for example the anatomical (and functional) mapping of disease-specific neural circuits.
Medical engineering has a pivotal role to play in this field through the development of safe and effective ‘closed loop’ implantable microchips to facilitate accurate delivery and recording of electrical impulses to target areas.

Neuromodulation is the process whereby an implantable device is used to reversibly alter the activity of the nervous system.
Spinal cord stimulation is a technique that has been used to successfully relieve pain for over 40 years in many thousands of patients. Sacral nerve stimulation is a technique related to spinal cord stimulation, except that the electrodes are placed along the sacral nerves in their spinal foraminae, rather than along the spinal cord.
Peripheral nerve stimulation is a technique in which an electrode is surgically placed adjacent to a peripheral nerve. Intraspinal nerve root stimulation is a technique related to spinal cord stimulation, except that the electrodes are placed along the nerve rootlets in the spinal canal, rather than over the spinal cord itself. Spinal infusion pumps enable the constant administration of miniscule amounts of potent medications to the spinal cord and nerve roots.
These systems can provide remarkable pain relief, even when all other therapies have failed.

It is a common co-morbidity and is linked to age-related disease such as type 2 diabetes and cancer, so its incidence is likely to further increase over time.
Dose-limiting side effects of – and the observation that many patients are simply refractive to pharmacological interventions – mean that the disease has one of the highest levels of unmet medical need in any therapy area. One such area where neuromodulation research and development is focused is neuropathic pain, whereby the targeted modulation of neurons can inhibit pain signals and so reverse the disease state.  Success with implantable neuromodulation devices has been demonstrated by medical technology companies.

There are a number of different neuromodulation techniques, which differ according to their application, underlying mechanisms, and invasiveness.
During this outpatient procedure, a small electrode is placed in the epidural space adjacent to the spinal cord.
As for spinal cord stimulation, this is an outpatient procedure that requires local anesthetic only but no incisions. A weak electrical current then inhibits the transmission of painful impulses with that nerve, relieving pain within the sensory distribution of that nerve.

The system consists of a programmable pump that contains a reservoir of medication, and a spinal catheter to deliver it to the spinal canal. Though effective, these systems are a bit complex, requiring periodic refills of medication and vigilance by the patient to make sure the medication does not run out.

Safety and efficacy of spinal cord stimulation for the treatment of chronic pain: a 20-year literature review.
In this article, the respective mechanisms of action and efficacy of TENS(transcutaneous electrical nerve stimulation), rTMS ( repetitive transcranial magnetic stimulation), tDCS ( transcranial direct current stimulation) are described.
A number of devices that demonstrate considerable efficacy in chronic pain have received regulatory approval or are in late stage trials.

By altering the activity of certain pathways in the nervous system, pain may be immediately and dramatically relieved. Once in position, the electrodes generate a weak electrical current that interrupts the transmission of pain at a sacral nerve level. This technique is sometimes used to treat pain syndromes that are not amenable to treatment with other stimulation procedures.
Once in position, the electrodes generate a weak electrical current that interrupts the transmission of pain at a spinal nerve root level. This type of device is appropriate for patients who require large daily doses of narcotics to treat their chronic pain syndrome. When the medication runs out, or the system malfunctions, then the patient may go into drug withdrawal. In addition to the positive effects, side effects and complications are mentioned and discussed in detail. Companies such as St Jude, Boston Scientific and Medtronic are leading development activities in this field. Those that have been suggested to be of relevance to eating disorders (ED) are described below.
Once in position, the electrode generates a weak electrical current that interrupts the transmission of pain at a spinal cord level. It is safe, effective, well-tolerated, and can be used to treat many different types of chronic pelvic pain. It is used to treat some of the more focal abdominopelvic pain syndromes, such as pain following inguinal hernia repair.
Generally, patients will be considered for an infusion pump if they have exhausted all other reasonable treatment options, including neurostimulation. Despite their limitations, spinal infusion pumps enable even the most seemingly hopeless patients transcend the grip of chronic pain misery, obtain pain relief, and begin to live their lives again. In conclusion, neuromodulatory (neurostimulatory) techniques are highly recommended for the treatment of different types of pharmacoresistant pain.2. Targeted therapies using electrical and magnetic neural stimulation for the treatment of chronic pain in spinal cord injury.
It is safe, effective, well-tolerated, and can be used to treat many different types of chronic pain, including abdominal and pelvic pain.
Some of the most notoriously difficult pelvic pain syndromes that are refractory to all other treatments may be effectively treated with sacral nerve stimulation. Neurostimulation methodsNeurostimulation, as a treatment of pain method, has been shown to be beneficial for patients suffering from pharmacoresistant chronic pain.
Currently, neurostimulation methods are indicated only after exhaustion of all other therapies; however, it is expected that, in the near future, neurostimulation methods will become a first line treatment.
Chronic pain is thought to occur in up to 30% of the adult population, although some authors suggest that it is less than 10%; others researchers, particularly in developed countries, put the prevalence as high as 50%.
Neurostimulation methods are mainly used for chronic intractable pain, in which long-term treatment had been ineffective. Research domain criteria (RDoC): Toward a new classification framework for research on mental disorders. Invasive or non-invasive neurostimulation is often recommended for patients with chronic neuropathic pain lasting more than six months, which was refractory to well-established first and second-line analgesic therapy or in which first and second-line analgesic therapy produced unacceptable side effects. Transcutaneous electrical nerve stimulation (TENS)TENS is a simple and relatively little used method with several probable mechanisms of pain relief [10]. These techniques are rather inexpensive and non-invasive, but the evidence for their effectiveness is overall of low quality [26]. The restrictive definition of TENS is the administration by surface electrodes of electric current produced by a device to stimulate cutaneous sensory nerves to reduce pain, both acute and chronic. As the biological basis of analgesia by TENS remains speculative, the ‘gate control theory’ of pain was the most tenable explanation but now release of endogenous opioids is the most acceptable explanation.

Functional disturbances within frontostriatal circuits across multiple childhood psychopathologies.
A systematic review of the effects of neuromodulation on eating and body weight: Evidence from human and animal studies. Despite participants knowing that they received active TENS, there was no difference between active TENS and placebo TENS in subjective pain rating.
Blinding of an electrical modality such as TENS has always been difficult, and few studies have reported blinding of active TENS.[33]In summary, the present randomized clinical trial examined the effects of single treatments of HF-TENS and LF-TENS on knee OA pain and function. The use of various outcome measures, different frequencies, and an improved placebo provided insight for the management of knee OA pain with TENS.
The pilot study tested a series of outcome measures designed to parallel and validate animal models of TENS and to test the effects of TENS in a true double-blind manner.
Using PPT as an objective measure of pain sensitivity, showed that both HF-TENS and LF-TENS reduced primary hyperalgesia and that only HF-TENS reduced secondary hyperalgesia in people with OA. Quantitative sensory testing with cutaneous mechanical and heat pain measures was not affected by HF-TENS, LF-TENS, or placebo TENS, suggesting that TENS has no effect on cutaneous hyperalgesia.

Alternatively, it is possible that the participants with OA did not have cutaneous mechanical and heat hyperalgesia.


All treatments had similar but minimal effects on subjective pain measures, suggesting a placebo component of the effect of TENS.
Treatment of eating disorders can not remain “brainless”: The case for brain-directed treatments. The treatment of pain using rTMS began mainly as a test to demonstrate the efficiency of cortical stimulation.
Neuroimaging and neuromodulation approaches to study eating behavior and prevent and treat eating disorders and obesity. Stimulation of the motor cortex has been associated with pain relief in various pharmacoresistant pain syndromes. Repetitive transcranial magnetic stimulation reduces cue-induced food craving in bulimic disorders.
QST consisted of thermal stimulation, which measured the thermal sensation threshold and tactile sensation testing using von Frey hairs. Testing must be individualized by establishing individual motor thresholds.Contralateral motor stimulation provoked an immediate response and was associated with stimulation levels that produced relief from pain. Immediately after stimulation there is a temporary increase in pain, the changes in thermal threshold and tactile sensation. The benefits of rTMS, in the form of pain relief, are usually seen 2 to 4 days after treatment.
Types of pain suitable for rTMS stimulationIntractable chronic pain: neuropathic pain (postherpetic neuralgia), pain after stroke, deafferentation pain (very often after brachial plexus avulsion), trigeminal neuralgia, and thalamic pain. Other analgesic indications are atypical orofacial pain ) [10], spinal stenosis, low back pain, phantom pain, stump pain, KRBS, fibromyalgia, and migraines.Best practices, for neurostimulation have been standardized and are available in the European Federation of Neurological Societies for neurostimulation therapy for neuropathic pain (G. Lefaucheur, BA Simpson and RS Taylor, European Journal of Neurology 2007).rTMS, used in accordance with the guidelines, is considered to be a safe and non-invasive method of neuromodulation pain therapy. Our research has confirmed the benefits of rTMS stimulation in patients with trigeminal and orofacial pain. For most of patients, we observed a change in the nature and a reduction in the frequency of painful episodes.
Two patients in our research group became pain-free and 1 patient was indicated for cortical stimulation two years after stimulation [8-10].The use of rTMS in the treatment of chronic intractable pain is reserved for pain that does not respond to analgesics and for pain in which the cause is difficult to remove. If it can be demonstrated to have an analgesic effect, then rTMS could be considered for inclusion in the current methods of pain treatment [30].
The advantage of magnetic stimulation is that it is a non-invasive procedure that is not time-consuming. Before rTMS can be routinely used in the treatment of chronic pain, it is necessary to accurately determine the amount and duration for each stimulation session, thereby ensuring the optimal duration of effect. From our results it is possible to conclude that the more effective rTMS was obtained with 20 Hz stimulation if compared wit our results with 10 Hz stimulation [9].
These results were measured with subjective evaluation of the pain, VAS, and with objective measurement using QTS. In objective evaluation the tactile measurement proved to be more important, while the results from measurement of thermal thresholds were not significant.The two treatment groups (active vs. Another advantage over other neuromodulatory methods is the price of the equipment.rTMS has also been tested on healthy subjects and was found to cause facilitation of motor evoked potentials, leading to an alternative interpretation of the effects of rTMS, which involves the activation of plasticity in the cerebral cortex [37].
Another possible pathophysiological explanation is that low-frequency stimulation (1 Hz) reduces the activity of excitatory circuits in the human motor cortex. The most common cause of facial pain is pain of dental origin, which begins after dental reparation or dental surgeries.
Recent studies have suggested the involvement of the peripheral and central nervous system in the pathophysiology of atypical odontalgia.Today rTMS is used with short-term success in the treatment of pain, mostly neuropathic pain. Previous studies have confirmed the ability of high (> 1 Hz) rTMS to stimulate the M1 in the treatment of facial pain. They have shown that the application of rTMS to the M1 changes the thermal pain threshold in this and related areas.
Higher frequency rTMS (5-10 Hz) also reduces deafferentation intractable pain in spinal cord injury and in peripheral nerves. Subjective evaluation of intra-and inter-group VAS scores, compared with the control group, showed both immediate and delayed treatment effects in subsequent measurements.
The results of the VAS ratings are consistent with results of previous studies.Changes in thermal sensation were not statistically different between groups. Intragroup comparison confirmed the reduction of thermal threshold for hot air stimulation after repeated rTMS application. Some studies have confirmed the influence of rTMS to reduce the threshold for thermal stimulation of both cold air and hot air [14,15] Other studies however, have shown an increased thermal threshold for hot air stimulation after rTMS Inter-group comparisons of tactile sensations showed acute effects after repeated stimulation (days 2, 4 and 5) but not when measured using a longer interval (day 21). The best frequency of stimulation for the most effective pain treatment has not yet been resolved.
Further studies are needed to assess factors underlying therapeutic effects (change in cortical excitability, better antinociceptive control).It’s also to seek for optimal stimulation parameters (intensity,frequency, number and duration of stimulation sessions). Complications of rTMSLow frequency rTMS stimulation can cause nausea, probably via stimulation of the posterior cranial fossa. A more common problem is the formation of transient pain, which is precisely located and depends on the site of stimulation.7. Mechanisms of action tDCStDCS affects the brain’s motor cortex excitability, which in humans is in area M1 (gyrus precentralis). Stimulation with the anode increases excitability of cortical brain cells by affecting the GABAergic system through depolarization.
Cathode stimulation reduces excitability of cortical brain cells via hyperpolarization of the glutamate system.
Low electric current rapidly increases the electrical conductivity of biological membranes by increasing permeability to ions and both small and large molecules.
Neuroplasticity modulates the motor cortex through changes in opioid activity [7] glutamatergic, GABAergic, dopaminergic (D1 and D2 receptors), serotonergic and cholinergic system [25].Nicotine reduces inhibitory plastic changes after cathode stimulation and facilitatory plasticity after anode stimulation. The order of these conditions were counterbalanced and randomized across participants, with a one week rest between each condition.
This was achieved as the tDCS machine used, allowed for the use of a code to determine whether tDCS was active or inactive (sham). Within the sham condition, 50% of the unilateral stimulation and 50% of the bilateral stimulation was randomized for sham stimulation.
Single and paired-pulse TMS was used to assess the after-effects of unilateral, bilateral or sham stimulation on corticomotor excitability of the right M1 and motor function of the non-dominant left ECRL. Motor function was measured at each of these time points in all conditions by having participants complete a Purdue pegboard test with their left hand only. Importantly, all electrophysiological measures for each time point were measured prior to the performance of the pegboard, as post MEP facilitation and the effectiveness of SICI has been shown to be modulated immediately following the completion of the pegboard test.
They examined the effects of a single-session of unilateral stimulation, bilateral and sham stimulation on modulating motor function of the non-dominant limb and indices of corticomotor plasticity.
In healthy adults, the extent of motor function improvement and corticomotor plasticity were similar between unilateral and bilateral tDCS.
Nevertheless, the present data indicate that tDCS induces behavioral changes in the non-dominant hand as a consequence of mechanisms associated with use-dependent cortical plasticity and is not influenced by the tDCS electrode arrangement. DCS may facilitate long-term potentiation through membrane polarization and removal of Mg+ block but only those pathways activated during DCS (by a task or experimental stimulation) would benefit from this facilitation. In humans, transcranial electrical stimulation may also preferentially modulate networks with heightened oscillatory activity or preferentially change the progression of an active network during memory consolidation or synaptic downscaling [20]Anatomical specificity and functional specificity, through either ongoing activity-selectivity or input-selectivity, are not exclusive and may potentially be leveraged together in the development of rational tDCS protocols.
