A randomized, controlled trial of magnetic therapy for carpal tunnel syndrome

ABSTRACT Introduction: Magnet therapy has been proposed as a treatment for neurologic conditions. In this this trial we assessed the feasibility and efficacy of a magnet inserted into a wristband for carpal tunnel syndrome (CTS). Methods: Twenty‐two patients with mild to moderate CTS were randomized to wear a high‐dose or low‐dose “sham” magnetic wristband for 6 weeks. The primary outcome was the Symptom Severity Scale (SSS) of the Boston Carpal Tunnel Questionnaire. Secondary measures were nerve conduction studies (NCS), median nerve ultrasound, and compliance. Results: Compliance for both groups was >90%. Improvements in the mean SSS, NCS, and median nerve ultrasound did not reach statistical significance. Discussion: Magnet therapy via wristband is well‐tolerated. Further investigations in larger populations are needed to determine efficacy. Muscle Nerve 58: 310–313, 2018
