Supine Piriformis Stretch

The supine piriformis stretch is one of the most commonly prescribed positions for suspected piriformis syndrome. It places the piriformis (which crosses from the sacrum to the greater trochanter) on maximal length while keeping the lumbar spine in a neutral, supported position. Patients whose sciatic symptoms reproduce with the FAIR test (flexion-adduction-internal rotation) tend to respond best.
