Piriformis syndrome exercises are aimed at releasing tension in the muscle and therefore pressure on the sciatic nerve which causes Piriformis syndrome. Both stretching and strengthening exercises should be included as part of a full treatment and rehabilitation program.

Stretching exercises for the piriformis muscle help release spasm in the muscle and therefore pressure on the sciatic nerve whilst strengthening ensures the muscle is strong enough to cope with the demands placed on it, preventing the injury recurring.
Piriformis syndrome exercises - stretching
Due to the position of the piriformis muscle in the hip, static stretches are more appropriate. Static stretching is where the stretch is applied then held for a period of time. It is important the stretch is not forced by is applied gently. The piriformis muscle itself should be stretched on a daily basis and in the early stages at least 3 times a day may be required. In addition, other stretching exercises for the groin and other buttock muscles will help ensure the joint is balanced.
Outer hip stretch (play video)
To stretch the muscles that rotate the hip outwards. Lie on your back and bend the knee of the leg to be stretched. Use the opposite hand to pull the knee over to the side as shown opposite. You should feel this in the hip and buttocks. Hold the stretch for 20 to 30 seconds, repeat 3-5 times and stretch 3 times a day.
Piriformis stretch (play video)
Lay on your back and bend both knees with the feet flat on the floor. Place the outer foot of the leg you wish to stretch on the lower thigh/knee of the other leg. Grip behind the thigh and pull this knee in towards your chest. You should feel a stretch in the buttock. Hold this position for 30 seconds, repeat 3-5 times and stretch 3 times a day.
Another version of this stretch can be done standing up where the knee is placed under and across the body resting on a table. The patient then leans forward using bodyweight to increase the stretch.
Long adductor stretch (play video)
It is important to stretch the long adductor muscles which attach at the knee as well as the short adductor muscles which attach above the knee. Long adductor muscles need to be stretched with a straight leg. This can be done either sitting or standing. Short adductor muscles are stretched with the knees bent.
Short adductor muscle stretch (play video)
Sit on the floor and put the soles of your feet together. Use your elbows to apply a gentle downward pressure to your knees to increase the stretch. You should feel a stretch on the inside of the thigh. Hold this position for 30 seconds, repeat 3-5 times and stretch 3 times a day.
Muscle energy technique
With a partner lie on your front and get the partner to rotate the bent leg outwards (towards the horizontal) as far as it will comfortably go. Then the athlete applies gentle pressure at about 25% effort to try and return the leg to the vertical. The partner resists this movement.
Hold this pressure for about 10 seconds and then relax. The partner then moves the leg further to stretch the muscle and holds this position for 30 seconds. Repeat this process until you get no further improvements in mobility. This is an excellent stretching method and has produced some exceptional and instantaneous results. This should only be done by trained therapists.
Foam roller piriformis syndrome exercises
The foam roller (play video) is used to apply deep tissue myofascial release massage to the muscle. One leg is placed across the other to put the muscle on stretch. The athlete then moves over the roller in a slow and controlled manner working backward and forwards along the length of the muscle. This may be mildly uncomfortable but should not be painful. If you are not able to perform the exercise and keep the muscle relaxed then try performing the exercise a little more lightly. The aim is to relax the muscle and if it is tightening up through pain it is not working.
Piriforms syndrome exercises - strengthening
Strengthening the piriformis muscle itself and also the other hip abductor muscles can be helpful in preventing piriformis syndrome recurring.
Resistance band abduction (play video)
Stand with one end of the band tied around the ankle and the other end attached to a fixed object, close to the floor. Move the leg out to the side, away from the body, keeping the knee straight. Once you get as far as is comfortable, slowly return the leg back to the center. Repeat 15 times and gradually build this up to 2 sets of 20 reps.
Side-lying clam exercise (play video)
Lay on your side with the hip to be worked on top. Bend your knees and position them forwards so that your feet are in line with your spine. Make sure your top hip is directly on top of the other and your back is straight. Keeping the ankles together, raise the top knee away from the bottom one.
Remember, don't move your back or tilt your pelvis, all the movement should be coming from the hip. Slowly return it to the starting position. Repeat 15 times initially and gradually build this up to 2 sets of 20.
Hip extension exercise (play video)
Position yourself on all fours. Shift your weight slightly off the leg to be worked. Keeping the knee bent, raise the knee off the floor so that the sole of the foot moves towards the ceiling. Slowly lower the leg, almost back to the starting position and repeat. Repeat 15 times initially and gradually build this up to 2 sets of 20.
