Sacroiliac Joint Manipulation Effect in Chronic Piriformis Syndrome.

Study Overview
=================
Brief Summary
-----------------
The objective of the study was to determine the effects of sacroiliac joint thrust manipulation on pain, pain pressure threshold, piriformis length and straight leg raise, in chronic piriformis syndrome.

Detailed Description
-----------------
In 2017, a systematic review was conducted to measure the effectiveness of physical therapy approach for relieving the SIJ pain linked with PS. Participants were administered with conservative physical therapy, Kinesiology taping and sacroiliac joint manipulation in group A, group B and group C respectively. They have concluded that Sacroiliac joint manipulation was more effective as compare to the rest of the physiotherapy approach in lowering the SIJ pain associated with piriformis syndrome. In 2014, an experimental study was conducted to compare the effects of nerve mobilization technique with conventional physical therapy approach. Pre and post treatment data was taken from the respective participants. The results of this study concluded that there is a significant differences in the outcome measures of both groups and nerve MOBS were proven to be more effective in relieving the sciatic nerve radiating pain associated with inflamed piriformis muscle in PS. A study in July, 2012 was conducted to compare the effects of two possible physical therapy treatments in lowering the low back pain threshold associated with piriformis syndrome. These two techniques were METs and SCS. Their results concluded that both Muscle energy technique and Strain counter strain were proved to be equally effective in the management of functional disability and pain in low back associated with chronic PS. An RCT was conducted in 2011, to measure the effectiveness of two possible manipulation methods which can be applied in patients with chronic piriformis syndrome. According to this study, manipulating the of SIJ along with lumber manipulation is more effective as compare to the SIJ manipulation alone to regain the total piriformis length for patients with Chronic PS. Another study was conducted by Gopal Nambi and colleagues in Saudi Arabia. It was concluded that Program comprises of Post Isometric Relaxation is more effective as compare to conservative physical therapy in alleviating the pain, improving hip ROM and functional improvement in participants with PS.
