To the Editor: Dr Collacott and colleagues1 provide little information on the magnetic device used in their study, although they report that it had weak flux density, averaging 300 G. However, a previous study demonstrated successful treatment of low back and knee pain with a 2000 G magnetic design.2 In this, as well as other clinical studies on magnetic therapy,3,4 specifications regarding the magnets used in each study were minimal or completely absent.
