Myofascial aspects of low back pain.

Myofascial TrPs are an often overlooked but treatable source of pain and discomfort in the low back. They often complicate or coexist with other causes of low back pain, and they can mimic other neuromuscular or back musculoskeletal problems. Successful treatment of myofascial pain requires the identification of TrPs by manual examination, identification of mechanical or systemic perpetuating factors, treatment of the specific TrPs, and corrective action to prevent their recurrence.
