"* Moist hot pack (10 minutes)~* Isometric quadriceps exercises (10 repetitions)~* Straight leg raise (10 repetitions)~ART steps:~* Subject lies on the plinth in prone or in side lying position with the dominant side facing upwards.~* Gentle tension is applied to the hamstring muscle along the entire length while stretching the leg in prone lying or side lying positions, depending on the level of pain and tightness of muscle (5 repetitions at 5 seconds interval).~* Gentle tension is also applied at the origin and insertion of the hamstring muscle until the patient feels full release."

"* Moist hot pack (10 minutes)~* Isometric quadriceps exercises (10 repetitions)~* Straight leg raise (10 repetitions)~PNF technique steps:~* The subject is in supine position with his non-dominant leg strapped down the table while the dominant leg rests on the therapist right shoulder.~* The therapist stretches the hamstring muscle until the subject first reports a mild stretch sensation; held for 7 sec by passively flexing the hip with knee fully extended, allowing no hip rotation.~* Next, the subject isometrically contracts the hamstring muscle for 3 sec and then relax for 5 sec.~* This sequence is repeated 5 times at a 20 second interval."
