The Physical Therapy department at Armstrong Atlantic State University conducted a Randomised Clinical Trial using static magnets on myofascial trigger point pain. The 2004 study was part of the student capstone project and supervised by professors of the physical therapy department. Although the study wasn’t published, the results were presented at the Bioelectromagnetics Society annual meeting.
A 1997 clinical trial by Vallbona, showed a significant benefit to patients suffering post-polio pain using a flexible rubber magnet with concentric rings in alternating poles. The study at Armstrong involved 30 patients and tested the same magnets as the Vallbona study, but on a more general population.
