Immediate effect of myofascial stretch dry needling versus traditional dry needling in subjects with myofascial trigger points in piriformis syndrome- A randomized control trial

Piriformis syndrome is a neuromuscular disorder that can cause symptoms of buttock pain,numbness radiating to the back of thigh due to irritation to sciatic nerve. Anytime the piriformis muscle becomes inflamed or irritated, it can affect the sciatic nerve and cause pain. Many factors can contribute to the development of piriformis syndrome such as trauma or anatomic anomalies Myofascial trigger points are the most common cause and also hyperthrophy in the piriformis muscle tissue,inflammation,trauma, and anatomic variations of the piriformis muscle or sciatic nerve may cause the development of piriformis syndrome.However in present study,immediate effect of myofascial stretch dry needling versus traditional dry needling in subjects with myofascial trigger points in piriformis syndrome in improving pain and disability.  60 subjects age between 18-70years diagnosed with piriformis syndrome will be selected based on inclusion criteria. All subjects will be assessed using VAS,pressure pain threshold, Oswestry disability index ,goniometer. All participants will be  randomly allocated into two groups: Group 1 and Group 2.Group1(myofascial stretch dry needling ) and in group 2(traditional dry needling). Thereafter subjects of group 1(n=30)will undergo myofascial stretch dry needling , whereas group2(n=30) will be treated with traditional dry needling . Subjects receive a single session of DN. The location on piriformis muscle were needled for 1 minute.The intervention will be given for 1 day to all subjects . After treatment, the post intervention asessment will be done using same outcome measures on same day.
