Treatment Validation for Myofascial Pain

Inclusion Criteria: * Ages 20-70; * Predominantly axial LBP (meeting NIH definition of cLBP with daily pain for at least 3 months) with a MP component as determined by the standardized examination for MP; * Average pain score of \> 3/10, with low back pain being the primary pain site; * CLBP meeting Quebec Task Force Classification System categories I-III (from axial pain only to pain radiating beyond the knee without neurological signs).
