“…Our patient showed substantial pain relief with ETOIMS in agreement with previous studies demonstrating positive effects of needle ETOIMS in musculoskeletal pain [17,19]. In addition to the conventional methods, we utilized ultrasonogaphy for real-time guidance during the procedure, thereby ensuring safe treatment of the muscles without any damage to nearby neurovascular structures.…”

Highlights• Disputed thoracic outlet syndrome (TOS) can be one of the possible causes of post-stroke pain.• Ultrasound-guided electrical twitch-obtaining intramuscular stimulation can be used as a safe and minimally invasive technique for the treatment of the disputed TOS.• Large-scale randomized controlled studies are needed to confirm its therapeutic efficacy. ABSTRACTIn post-stroke patients, the pain or paresthesia of the affected limb is common. These symptoms may be caused by a variety of pathologic conditions. Considering the debilitating effects of the pain, it is important to determine the exact cause and manage appropriately. A 41-year-old woman who had experienced a hemorrhagic lesion in the right basal ganglia and corona radiata 4 months previously presented with an irritating tingling sensation in her left upper extremity. She failed to respond to a number of treatment options including medications and physical agent modalities. Following a diagnosis of disputed thoracic outlet syndrome (TOS) caused by scalene muscle dysfunctions, she received ultrasoundguided electrical twitch-obtaining intramuscular stimulation (ETOIMS) which significantly alleviated the pain. This case suggests that the disputed TOS should be considered as one of the possible causes of post-stroke pain, and that detailed history-taking and physical examination, as well as imaging or electrophysiological studies, might be required for accurate diagnosis. Furthermore, ultrasound-guided ETOIMS can be used as a safe and minimally invasive technique for the treatment of the disputed TOS with fewer systemic and local side effects.

“…Several investigations have reported that IMES can be an effective modality on musculoskeletal pain [12][13][14][15][16]; however, few relevant studies could be found which reported effects of the IMES on myofascial trigger points [14,16]. To our knowledge, there is no study comparing the IMES and placebo approaches in patients with the MTrPs.…”

Introduction: Myofascial Pain Syndrome (MPS) is a common disorder of musculoskeletal system. About one third of the people with musculoskeletal disorders have been diagnosed as having MPS. It is a painful condition caused by trigger points. A variety of treatment approaches are used to cure MPS and its associated disorders. This study aimed to investigate the effects of single session Intramuscular Electrical Stimulation (IMES) through dry needling on pain and Range Of Motion (ROM) following trigger points in upper trapezius. Materials and Methods:Sixteen volunteers with active trigger points in upper trapezius were randomly divided into two groups: 1) the IMES treatment group (8 females) and 2) placebo group (8 females). In the IMES group, trigger points of the affected side were injected through dry needling, then a burst current (2 Hz) was applied on the muscle while the electrical stimulation steadily increases to form a pain free contraction for the patient. In placebo group, the procedure was exactly the same but there was no applied electrical stimulation through dry needling. Pain sensation by Visual Analog Scale (VAS) and cervical flexion ROM were measured before treatment, immediately after treatment and one week later by another blinded researcher.Results: VAS scores showed improvement in both groups at the end of the treatment session and also one week later. There was no significant difference between the groups; IMES and placebo in terms of the VAS after treatment session. However, the pain scores were substantially decreased in the IMES group one week after the intervention. The ROMs were significantly lower in placebo group one week after treatment. There was no significant correlation between improvement and duration of symptoms. Conclusion:Both IMES and placebo methods might be effective in relieving symptoms of patients with the MPS in upper trapezius; however, patients following the IMES treatment showed higher level of improvement during one week after the intervention. Further relevant studies with higher number of volunteers and different treatment protocols are necessary to get high quality evidence.

“…Thus, this study can provide theoretical support for practical applications that use needle electrodes to deliver stimuli. These applications include intraoperative detection of motor pathways during tumor resection [47,50]; preoperative or experimental stimulation of the pudendal nerve [51] or the micturition center of the brain [6] to control bladder function; electro-acupuncture for analgesia [4,13] and peripheral nerve regeneration [16]; tinnitus suppression [19]; and intramuscular delivery of plasmid DNA [45]. Many of these applications would benefit from more accurate prediction of where the stimulation takes place: which fibers are stimulated or blocked, and what the recruitment order is.…”

We present an analytical solution for the electrical potential and activating function (AF) established by cylindrical needle electrodes in anisotropic tissue. We compare this activating function to (1) AF computed assuming line-source electrodes and (2) AF computed using a finite element program. The results show that when the fiber is two needle diameters away from the electrodes, the maximum of the AF for needle electrodes is 1.43-times larger than for line-source electrodes, which results in lower thresholds for stimulation and electroporation. Therefore, for fibers that are close to the stimulating electrodes, one would benefit from using the formula that accounts for the electrodes' geometry.
