Comparative Effect of Active Release Technique Versus Self-myofascial Release in Improving Piriformis Syndrome

Piriformis is a key internal rotator of the hip which develops muscular imbalance due to overuse and pressure. There are various disabling conditions caused due to a simple tightness of Piriformis muscle like low back pain, sciatic nerve pain through muscle hypertrophy or a nearby anomaly due to its anatomically closeness to the sciatic nerve, pain and aesthesia in hip, thigh, calf and foot are symptoms that commonly occur in Piriformis syndrome. Piriformis syndrome is defined as a peripheral neuritis of the branches of the sciatic nerve caused by an abnormal condition of the piriformis muscle (PM), such as an injured or irritated muscle. MFR technique involves application of a low load-long duration stretch to the myofascial complex which intends to restore the optimal length, decrease pain and improve functional mobility of the muscle. A special technique within MFR is self-myofascial release (SMFR), performed by the patient independently, instead of by a therapist. This technique utilizes the patient's body mass and special tools such as massage balls or foam rollers to apply pressure and stretch the restricted soft tissue. Active Release Techniques (ART) are a soft tissue method that focuses on relieving tissue tension via the removal of fibrosis/adhesions which can develop in tissues as a result of overload due to repetitive use. Active release technique will be applied on group A by the physiotherapist and self-myofascial release will be applied on group B by the patients themselves through the use of foam-rollers and massage ball to compare the results of both these techniques on reducing pain, improving range and functional disability among individuals with piriformis syndrome.
