Effects of repetitive functional magnetic stimulation in the sacral nerve in patients with neurogenic detrusor overactivity after suprasacral spinal cord injury: a study protocol for a randomized controlled trial.

BACKGROUND: Neurogenic detrusor overactivity (NDO) is a serious and common complication after spinal cord injury, affecting patients' quality of life seriously. Therefore, we developed this research protocol to evaluate the efficacy of repetitive functional magnetic stimulation (rFMS) in the sacral nerve in patients with neurogenic detrusor overactivity (NDO) after suprasacral spinal cord injury (SCI) and provide more options for rFMS in treating NDO after suprasacral SCI. METHODS: This study is a single-center, randomized, parallel-group clinical trial. We will recruit the patients with NDO after suprasacral SCI in the Rehabilitation Department of the Affiliated Hospital of Southwest Medical University from September 2022 to August 2023. They will be assigned to the rFMS group and the sham stimulation group randomly. The sample size is 66, with 33 patients in each group. The rFMS group will receive real rFMS treatment of the sacral nerve (100% stimulation intensity, 5 Hz, 20 min each time, five times a week), and the sham group will receive sham stimulation. Both groups will receive similar treatment strategies, including medication, standard urine management, acupuncture treatment, and health education. The bladder compliance (bladder capacity/detrusor pressure) and pudendal nerve electromyography will be evaluated at baseline, 8th week of treatment. The residual volume of the bladder and bladder diary will be recorded once a week during 8 weeks of treatments. SCI-QOL and NBSS will be evaluated at baseline, the 4th and 8th week of treatment. In addition, the above assessments will be followed up at 8 weeks after the end of treatment. DISCUSSION: It is expected that the bladder function, symptoms, and quality of life might be significantly improved after rFMS of the sacral nerve. TRIAL REGISTRATION: The China Clinical Trials Registry has approved this study, registration number: ChiCTR2100045148. Registered on April 7, 2021.

Effects of repeated transcranial magnetic stimulation in the dorsolateral prefrontal cortex versus motor cortex in patients with neuropathic pain after spinal cord injury: a study protocol.

INTRODUCTION: Neuropathic pain is one of the common complications of spinal cord injuries (SCI), which will slow down the recovery process and result in lower quality of life. Previous studies have shown that repeated transcranial magnetic stimulation (rTMS) of the motor cortex (M1) can reduce the average pain and the most severe pain of neuropathic pain after SCI. The dorsolateral prefrontal cortex (DLPFC) area is a common target of rTMS. Recently, a few studies found that rTMS of DLPFC may relieve the neuropathic pain of SCI. Compared with the M1 area, the efficacy of rTMS treatment in the DLPFC area in improving neuropathic pain and pain-related symptoms in patients with SCI is still unclear. Therefore, our study aims to evaluate the non-inferiority of rTMS in the DLPFC vs M1 in patients with neuropathic pain after SCI, in order to provide more options for rTMS in treating neuropathic pain after SCI. METHODS AND ANALYSIS: We will recruit 50 subjects with neuropathic pain after SCI. They will be randomly assigned to the DLPFC- rTMS and M1-rTMS groups and be treated with rTMS for 4 weeks. Except for the different stimulation sites, the rTMS treatment programmes of the two groups are the same: 10 Hz, 1250 pulses, 115% intensity threshold, once a day, five times a week for 4 weeks. VAS, simplified McGill Pain Questionnaire, Spinal Cord Injury Pain Date Set, Pittsburgh Sleep Quality Index and Hamilton Anxiety Scale will be evaluated at baseline, second week of treatment, fourth week of treatment and 4 weeks after the end of treatment. And VAS change will be calculated. ETHICS AND DISSEMINATION: The Ethics Committee of the Affiliated Hospital of Southwest Medical University has approved this trial, which is numbered KY2020041. Written informed consent will be provided to all participants after verification of the eligibility criteria. The results of the study will be published in peer-reviewed publications. TRIAL REGISTRATION NUMBER: ChiCTR2000032362.

Effects of shock wave therapy in patients with carpal tunnel syndrome: a systematic review and meta-analysis.

PURPOSE: To determine whether shock wave therapy could improve symptoms and hand function in patients with carpal tunnel syndrome. MATERIALS AND METHODS: Medline, Embase, Physiotherapy Evidence Database, the Cochrane Central Register of Controlled Trials, OpenGrey, CNKI, VIP, Wang Fang databases, and China Biological Medicine were searched, from inception to December 2019. RESULTS: Ten trials involving 433 patients (501 wrists) were included in this systematic review. The shock wave therapy was observed to have a significant effect on pain relief (MD: -0.60, 95% CI: -1.16 to -0.05, p = 0.03), syndrome alleviation (MD: -2.26, 95% CI: -3.24 to -1.27, p < 0.00001) and functional recovery (MD: -1.25 95% CI: -2.08 to -0.43, p = 0.003) among the carpal tunnel syndrome patients. As revealed by the subgroup analysis, radial shock wave therapy made a significant difference in pain relief, syndrome alleviation, and functional recovery (p < 0.05). Focused shock wave had no significant effect on pain relief, syndrome alleviation, and functional recovery (p > 0.05). CONCLUSION: Shock wave therapy could be conductive to improve syndrome and hand function for carpal tunnel syndrome patients.Implications for rehabilitationShock wave therapy is beneficial for alleviating syndrome and improving hand function of carpal tunnel syndrome patients.Radial shock wave therapy seems superior to focused shock wave therapy on syndrome alleviation and functional recovery of hand in carpal tunnel syndrome patients.
