The study aimed to investigate the efficacy of a single session of repetitive peripheral magnetic stimulation (rPMS) in patients with carpal tunnel syndrome (CTS) caused by median nerve compression. The sample consisted of 34 CTS patients who had been receiving treatment for more than six weeks (medication and exercise). They were randomly divided into two groups: 17 participants in the experimental group received a single session of rPMS, while 17 participants in the control group received sham rPMS. Both groups continued receiving standard treatment. Evaluations included pain scores (VAS), grip strength, and the Thai version of the Boston Carpal Tunnel Questionnaire (Thai BCTQ). Assessments were conducted at baseline, 15 minutes after treatment (VAS, grip strength), and one week post-treatment (VAS, Thai BCTQ).The research instrument used was a repetitive peripheral magnetic stimulation machine, following a protocol designed by the researchers. Data analysis was performed using the following statistical methods: 1) comparison of pain and numbness scores (VAS) with the Independent t-test, 2) comparison of grip strength with the Independent t-test, and 3) comparison of Thai BCTQ scores with the Independent t-test.
The results showed that a single session of rPMS in CTS patients did not demonstrate superior effects compared to the sham group in reducing pain and numbness (15 minutes post-treatment: -0.59 (-1.87, 0.70), P = 0.370; one week post-treatment: -1.00 (-2.44, 0.44) or in improving hand strength (-0.12 (2.04, 1.81), P = 0.902) and Thai BCTQ scores (-0.09 (-0.47, 0.30), P = 0.652).
