Magnet Therapy
Strong evidence supports not using magnet therapy for the treatment of carpal tunnel syndrome.

Rationale

Several high quality studies (Colbert 2010, Weintraub 2008) evaluated the use of magnets in treating carpal tunnel syndrome.  In a prospective randomized double-blinded controlled trial, Weintraub 2008 evaluated the efficacy of a magnet (simultaneous static and time-varying dynamic magnetic field stimulation 4 hours/day for two months).  No significant measures of improvement were noted.  In a randomized, double-blind controlled trial, Colbert 2010 evaluated the efficacy of magnet (wore nightly for 6 weeks a neodymium magnet of 15 or 45mTesla) versus placebo magnet on the treatment of carpal tunnel syndrome.  No significant measures of improvement were noted.
