Tension myositis syndrome
Tension myositis syndrome (TMS), also known as tension myoneural syndrome or mindbody syndrome, is a name given by John E. Sarno to what he claimed was a condition of psychogenic musculoskeletal and nerve symptoms, most notably back pain. Sarno described TMS in four books, and stated that the condition may be involved in other pain disorders as well.
