Use of Manual Therapy for Posterior Pelvic Girdle Pain.

Use of manual therapies in the treatment of posterior pelvic pain is a common practice. The rationale for use of manual therapies is often associated with the structural movement of the sacroiliac joint. Increasing evidence has shown this not to be the case, as manual therapy's effect is more neurophysiological in nature. This article seeks to clarify the difference between the two explanations as well as to expand upon outside influences such as expectations, therapeutic alliance, and equipoise that may influence the outcome of treatment. Treatment effects may be maximized with manual therapy if clinicians have an understanding of the role of each of these variables in their treatment approach.
