Myofascial pain syndrome (MPS) is a common musculoskeletal disorder that significantly affects quality of life. Conventional treatment approaches include pharmacological interventions, physical therapy, and procedures such as dry needling. Among these, ultrasound-guided injections (USGIs) have gained recognition for their precision and therapeutic benefits. Additionally, repetitive peripheral magnetic stimulation (rPMS) has emerged as a non-invasive neuromodulatory technique for pain management. This perspective article examines the physiological mechanisms and clinical applications of USGIs and rPMS, particularly in the lumbar multifidus muscle, and explores their potential synergistic effects. MPS is often associated with chronic muscle dysfunction due to energy depletion, leading to persistent pain and motor impairment. USGIs play a crucial role in restoring muscle perfusion, disrupting pain cycles, and providing diagnostic insights in real time. In parallel, rPMS modulates neuromuscular activation, enhances endogenous pain control, and promotes functional recovery. Ultrasound guidance enhances the precision and effectiveness of interventions, such as dry needling, interfascial plane blocks, and fascial hydrodissection, while rPMS complements these strategies by facilitating neuromuscular reconditioning and reducing pain via central and peripheral mechanisms. The preliminary findings suggest that combining multifidus USGIs with rPMS results in significant pain relief and functional improvements in patients with chronic low back pain. Integrating USGIs with rPMS represents a promising multimodal strategy for managing MPS. By combining targeted injections with non-invasive neuromodulation, clinicians may optimize therapeutic outcomes and provide sustained relief for patients with chronic musculoskeletal pain. Further research is needed to refine treatment protocols and assess the long-term efficacy. Full article

Background/Objectives: Innovative therapies are needed to reduce disability, facilitate activities of daily living, and improve the quality of life in patients with stroke. Non-invasive methods of stimulating the peripheral and central nervous system are increasingly being used to enhance the effects of existing therapies in stroke rehabilitation. One potentially relevant method for achieving greater improvement is repetitive peripheral magnetic stimulation (rPMS). This randomized controlled trial (RCT), the Peripheral MAgnetic stimulation in patients with spastic hemiparesis after Stroke Trial (REPMAST), will investigate whether rPMS improves upper extremity function, spasticity, and activities of daily living in patients with stroke compared with neuromuscular stimulation (NMS). Methods: REPMAST is an interventional, randomized controlled single-blinded study. Patients with subacute stroke are randomized to receive rPMS or NMS five days a week for three weeks in addition to standard rehabilitation therapy. The primary outcome is the change in the Fugl–Meyer Assessment for Upper Extremity between the beginning and end of the stimulation sessions. Secondary outcomes include changes in the Katz Index of Independence in Activities of Daily Living, the Timed Up and Go Test, the Modified Ashworth Scale, and the Tardieu Scale. A total sample size of 138 patients (69 in each group) is required to investigate the superiority of rPMS compared with NMS. Conclusions: The aim of this RCT is to provide evidence for an effective peripheral stimulation treatment for stroke recovery. Full article

Background: The reduction of muscular hypertonia is important in the treatment of various diseases or rehabilitation. This study aims to test the efficacy of a 5 Hz mechanical muscle stimulation (tapotement massage) in comparison to a 5 Hz repetitive peripheral magnetic stimulation (rPMS) on the neuromuscular reflex response. Methods: In a randomized control trial, 15 healthy volunteers were administered with either 5 Hz rPMS, tapotement massage, or rPMS sham stimulation. The posterior tibial nerve was stimulated with rPMS and sham stimulation. The Achilles tendon was exposed to a mechanically applied high-amplitude 5 Hz repetitive tendon tapotement massage (rTTM). The tendon reflex (TR) was measured for the spinal response of the soleus muscle. Results: After rPMS, there was a reduction of the TR response (−9.8%, p ≤ 0.034) with no significant changes after sham stimulation. Likewise, TR decreased significantly (−17.4%, p ≤ 0.002) after Achilles tendon tapotement intervention. Conclusions: These findings support the hypothesis that both afferent 5 Hz sensory stimulations contributed to a modulation within the spinal and/or supraspinal circuits, which resulted in a reduction of the spinal reflex excitability. The effects could be beneficial for patients with muscle hypertonia and could improve the functional results of rehabilitation programs. Full article

Migraine has a relevant impact on pediatric health. Non-pharmacological modalities for its management are urgently needed. This study assessed the safety, feasibility, acceptance, and efficacy of repetitive neuromuscular magnetic stimulation (rNMS) in pediatric migraine. A total of 13 patients with migraine, ≥6 headache days during baseline, and ≥1 myofascial trigger point in the upper trapezius muscles (UTM) received six rNMS sessions within 3 weeks. Headache frequency, intensity, and medication intake were monitored using headache calendars; headache-related impairment and quality of life were measured using PedMIDAS and KINDL questionnaires. Muscular involvement was assessed using pressure pain thresholds (PPT). Adherence yielded 100%. In 82% of all rNMS sessions, no side effects occurred. All participants would recommend rNMS and would repeat it. Headache frequency, medication intake, and PedMIDAS scores decreased from baseline to follow-up (FU), trending towards statistical significance (p = 0.089; p = 0.081, p = 0.055). A total of 7 patients were classified as responders, with a ≥25% relative reduction in headache frequency. PPT above the UTM significantly increased from pre- to post-assessment, which sustained until FU (p = 0.015 and 0.026, respectively). rNMS was safe, feasible, well-accepted, and beneficial on the muscular level. The potential to reduce headache-related symptoms together with PPT changes of the targeted UTM may underscore the interplay of peripheral and central mechanisms conceptualized within the trigemino-cervical complex.

Sarcopenic dysphagia requires the presence of both dysphagia and generalized sarcopenia. The causes of dysphagia, except for sarcopenia, are excluded. The treatment for sarcopenic dysphagia includes resistance training along with nutritional support; however, whether rehabilitation procedures are useful remains unclear. In this narrative review, we present possible rehabilitation procedures as a resistance training for managing sarcopenic dysphagia, including Shaker exercise, Mendelsohn maneuver, tongue-hold swallow exercise, jaw-opening exercise, swallow resistance exercise, lingual exercise, expiratory muscle strength training, neuromuscular electrical stimulation, and repetitive peripheral magnetic stimulation. We hope that some procedures mentioned in this article or new methods will be effective to treat sarcopenic dysphagia. Full article

Neuromodulators at the periphery, such as neuromuscular electrical stimulation (NMES), have been developed as add-on tools to regain upper extremity (UE) paresis after stroke, but this recovery has often been limited. To overcome these limits, novel strategies to enhance neural reorganization and functional recovery are needed. This review aims to discuss possible strategies for enhancing the benefits of NMES. To date, NMES studies have involved some therapeutic concerns that have been addressed under various conditions, such as the time of post-stroke and stroke severity and/or with heterogeneous stimulation parameters, such as target muscles, doses or durations of treatment and outcome measures. We began by identifying factors sensitive to NMES benefits among heterogeneous conditions and parameters, based on the “progress rate (PR)”, defined as the gains in UE function scores per intervention duration. Our analysis disclosed that the benefits might be affected by the target muscles, stroke severity and time period after stroke. Likewise, repetitive peripheral neuromuscular magnetic stimulation (rPMS) is expected to facilitate motor recovery, as already demonstrated by a successful study. In parallel, our efforts should be devoted to further understanding the precise neural mechanism of how neuromodulators make UE function recovery occur, thereby leading to overcoming the limits. In this study, we discuss the possible neural mechanisms. Full article
