@Lois I just found this information in the internet: FSM was developed by Dr. Carolyn McMakin in 1995 using frequencies passed on from an osteopath in Canada who had a practice that came with a machine made in the 1920’s. Dr. McMakin developed protocols for the treatment of myofascial pain in 1996 and presented her clinical data at the American Back Society national meeting in December 1997. In 1998, she published the paper on the “Treatment of chronic resistant myofascial pain in the head, neck, and face” in Topics in Clinical Chiropractic. In addition to other published FSM paper.

@MooieModer hi there, frequency specific microcurrent treatment (FSM) is similar to a TENS unit which uses electrical frequencies to treat pain except with FSM you can program different frequencies to treat different conditions. I have spinal RSD so the frequencies that worked well for me treat spinal cord injuries and nerve pain. During the treatment all you feel is a slight tingling, although I had to start very slow and build up gradually. I was very skeptical but after a few weeks of treatment I really started seeing improvement.
