Understanding Piriformis Syndrome

Piriformis syndrome is a neuromuscular condition in which the piriformis muscle — a small but powerful external rotator of the hip located deep in the gluteal region — becomes hypertonic, inflamed, or shortened, compressing or irritating the sciatic nerve as it passes beneath (or occasionally through) the muscle.

The hallmark symptoms include:

  • Deep buttock pain, often unilateral
  • Pain radiating down the posterior thigh, mimicking lumbar disc sciatica
  • Worsening with prolonged sitting, climbing stairs, or hip internal rotation
  • Tenderness over the greater sciatic notch on palpation

7 Piriformis Syndrome Exercises

1. Supine Piriformis Stretch (Figure-Four)

Position: Lying on your back, cross the affected leg over the opposite knee, forming a figure-four shape.

How: Gently pull the bottom thigh toward your chest until a stretch is felt deep in the buttock. Hold 30 to 60 seconds. Repeat 3 times.

Tip: The deeper you pull the thigh, the more intense the stretch. Work progressively.

2. Seated Piriformis Stretch

Position: Sit on a firm chair. Cross the affected ankle over the opposite knee.

How: Gently lean forward with a straight back until a stretch is felt in the buttock. Hold 30 to 45 seconds, 3 repetitions.

---

3. Standing Piriformis Stretch (Crossed-Leg)

Position: Cross the affected leg in front of the opposite leg while standing near a wall for support.

How: Slowly bend both knees into a mini-squat position. Hold 20 to 30 seconds. Good for those who cannot get to the floor.

4. Prone Hip External Rotation Stretch

Position: Lie face down. Bend the knee of the affected side to 90°.

How: Gently lower the bent foot outward (increasing internal rotation at the hip) until a deep stretch is felt in the buttock. Hold 20 to 30 seconds.

---

5. Clamshell Exercise (Strengthening)

Position: Lie on your side, hips and knees bent at 45°. Place a resistance band around your thighs if available.

How: Keeping feet together, lift the top knee toward the ceiling without rotating the pelvis. Hold 2 seconds. Lower slowly. 3 sets × 15 repetitions.

Purpose: Strengthens gluteus medius and reduces compensatory piriformis overload.

6. Hip Abductor Strengthening (Side-Lying Leg Raise)

Position: Lie on your side, bottom knee bent for stability.

How: Lift the top leg to 45°, hold 2 seconds, lower slowly. 3 sets × 12 repetitions. Progress with ankle weights.

---

7. Piriformis Neural Mobility (Sciatic Nerve Glide)

Position: Lie on your back.

How: Bring the hip to 90°, then alternate between knee straightening (producing sciatic nerve tension) and knee bending (releasing tension). Perform rhythmically for 20 repetitions. Do not hold in the stretched position — this is a dynamic neural mobilisation.

Caution: Discontinue if radiating pain increases significantly.

Positions and Activities to Avoid

  • Prolonged sitting (particularly on hard surfaces without cushion support)
  • Cross-legged sitting postures
  • Deep squat positions during the acute phase
  • Uphill running
  • Activities involving sustained hip internal rotation

When to See a Physiotherapist

If piriformis exercises fail to improve symptoms within 4 to 6 weeks, or if you develop neurological changes (weakness, numbness, foot drop), seek a comprehensive assessment. A physiotherapist can:

  • Differentiate piriformis syndrome from lumbar disc herniation or sacroiliac joint dysfunction
  • Apply targeted manual therapy, dry needling, or ultrasound to the piriformis
  • Design a progressive rehabilitation programme addressing hip strength and biomechanics
