Harvard Medical School professor Vitaly Napadow, who has a Ph.D. in biomedical engineering and is also a licensed acupuncturist says ''I've been practicing for eight years and have seen acupuncture help with surprisingly diverse issues, like plantar fasciitis and diabetic neuropathy,'' he said. ''Acupuncture affects many systems in the body, including parts of the brain that are involved with processing emotion and pain.''
