Short-term effect of muscle energy technique and mechanical diagnosis and therapy in sacroiliac joint dysfunction: A pilot randomized clinical trial.

Introduction: Sacroiliac joint dysfunction (SIJD) is a prominent source of pain in low back pain (LBP) patients. Tenderness inferior to the posterior superior iliac spine (PSIS) is an important sign presented in SIJD. Techniques including muscle energy technique (MET) and mechanical diagnosis and therapy (MDT) have shown benefits in SIJD.
