Some clinicians recommend formal physical therapy, including soft tissue mobilization, hip joint mobilization, teaching stretching techniques, and strengthening of the gluteus maximus, gluteus medius, and biceps femoris to reduce strain on the piriformis. More advanced physical therapy treatment can include pelvic-trochanter isometric stretching, hip abductor, external rotator and extensor strengthening exercises, transcutaneous electrical nerve stimulation (TENS), and massage physiotherapy of the piriformis muscle region. One study of 14 people with what appeared to be piriformis syndrome indicated that rehabilitation programs that included physical therapy, low doses of muscle relaxants and pain relief medication were effective at alleviating most muscle and nerve pain caused by what the research subjects had been told was piriformis syndrome. However, as this study included very few individuals and did not have a control group not receiving treatment (both serious methodological flaws), it provides no insight as to whether the pain in the piriformis would have simply dissipated on its own without any treatment at all, and is therefore not only uninformative, it may actually be misleading. The injury is considered largely self-limiting and spontaneous recovery is usually on the order of a few days or a week to six weeks or longer if left untreated. Stretching
Most practitioners agree that spasm, strain, or pain in any muscle can often be treated by regular stretching exercise of that muscle, no matter the cause of the pain. Stretching is recommended every two to three waking hours. Anterior and posterior movement of the hip joint capsule may help optimize the patients stretching capacity.
