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.

Keywords: alternative therapy for CTS; carpal tunnel syndrome; complementary therapy for CTS; magnet therapy; median nerve ultrasound; static magnetic field.
