Park et al1 reported on an excellent study evaluating the efficacy of traditional acupuncture for subacute stroke rehabilitation. However, there was no mention of potential mechanisms by which acupuncture might conceivably help stroke patients. While a discussion of potential mechanisms may be beyond the scope of such an article and is not required, it could help explain any findings, positive or negative, and is important given the rather widely differing viewpoints between traditional acupuncture and modern medicine.
