Piriformis Syndrome Exercises and Stretches

What is piriformis syndrome and why does it hurt?

The piriformis is a small, deep muscle in the buttock that runs from the sacrum to the top of the femur. It helps rotate the hip outward. In some people the sciatic nerve passes through or very close to this muscle. When the piriformis is tight, overloaded, or in spasm, it can compress nearby structures and produce:

• A deep, aching pain in the center of the buttock
• Pain that worsens with sitting, climbing stairs, or crossing the legs
• A radiating ache or tingling down the back of the thigh — sometimes as far as the calf

A systematic review of 55 studies found the cardinal features of piriformis syndrome are deep buttock pain, tenderness over the greater sciatic notch, pain worsened by sitting, and aggravation by maneuvers that tension the piriformis muscle 2Ref 2Hopayian K, Song F, Riera R, Sambandan S (2010).The clinical features of the piriformis syndrome: a systematic review.Systematic review of 55 studies establishing the cardinal features of piriformis syndrome: deep buttock pain, tenderness over the greater sciatic notch, pain worsened by sitting, and aggravation by maneuvers that tension the piriformis muscle. The radiating pattern can resemble lumbar disc sciatica, which is why an accurate diagnosis matters before starting exercises — treatment differs between the two 1Ref 1Kreiner DS, Hwang SW, Easa JE, et al.; North American Spine Society (2014).An evidence-based clinical guideline for the diagnosis and treatment of lumbar disc herniation with radiculopathy.Distinguishes lumbar radiculopathy from peripheral nerve compression as the basis for tailored PT evaluation — critical context for correctly diagnosing piriformis-adjacent sciatic symptoms.

Which stretches target the piriformis?

The following stretches are commonly used in physical therapy for piriformis syndrome. Hold each position for 20–30 seconds and repeat 2–3 times per side. Stop if pain sharpens or radiates further down the leg.

Figure-four (supine) Lie on your back, knees bent, feet flat. Cross the affected ankle over the opposite knee (forming a '4' shape). Gently press the crossed knee away from you, or draw both legs toward your chest. You should feel a stretch deep in the buttock.

Pigeon pose (modified, on the floor) From hands and knees, slide the affected knee forward behind your wrist and let the shin rest at an angle. Ease your hips toward the floor. This is a deeper stretch and may not be appropriate early on.

Seated piriformis stretch Sit in a chair, cross the affected ankle over the opposite knee, and gently lean forward with a flat back until you feel a stretch in the buttock.

Standing figure-four Stand near a wall for balance. Cross one ankle just above the opposite knee and slowly bend the standing leg as if sitting into a chair. Useful if getting to the floor is difficult.

Stretch gently — the piriformis responds poorly to aggressive, bouncing pressure.

What strengthening exercises help, and why?

Stretching alone is rarely sufficient. Weakness in the hip abductors and glutes often contributes to piriformis overload, because the piriformis compensates when stronger muscles are not doing their share.

Clamshells Lie on your side with hips and knees bent. Keeping your feet together, raise the top knee like a clamshell opening, then lower slowly. This targets the gluteus medius.

Side-lying hip abduction Lie on your side with the bottom leg bent for stability. Lift the top leg to about 45 degrees, pause, then lower. Use a resistance band when bodyweight becomes easy.

Bridges Lie on your back, knees bent. Drive through your heels to lift your hips until your body forms a straight line from knees to shoulders. This activates the gluteus maximus — a key stabilizer that, when strong, reduces demand on the piriformis.

Step-ups Step onto a low box or step, push through the heel, and stand fully before stepping down. Progress height gradually.

A PT will reinforce proper form, which is especially important when piriformis symptoms stem from movement-pattern faults rather than simple muscle tightness 1Ref 1Kreiner DS, Hwang SW, Easa JE, et al.; North American Spine Society (2014).An evidence-based clinical guideline for the diagnosis and treatment of lumbar disc herniation with radiculopathy.Distinguishes lumbar radiculopathy from peripheral nerve compression as the basis for tailored PT evaluation — critical context for correctly diagnosing piriformis-adjacent sciatic symptoms.

How does physical therapy approach this condition?

A physical therapist evaluates whether symptoms are coming from the piriformis itself, the lumbar spine, or both — because the two can coexist 1Ref 1Kreiner DS, Hwang SW, Easa JE, et al.; North American Spine Society (2014).An evidence-based clinical guideline for the diagnosis and treatment of lumbar disc herniation with radiculopathy.Distinguishes lumbar radiculopathy from peripheral nerve compression as the basis for tailored PT evaluation — critical context for correctly diagnosing piriformis-adjacent sciatic symptoms. Assessment typically includes checking hip range of motion, nerve tension tests, and lumbar spine provocation.

Treatment often combines: - Manual therapy (soft-tissue release, joint mobilization) - A progressive home exercise program starting with gentle stretching and advancing to loaded strengthening - Gait or movement retraining if asymmetries are contributing - Guidance on modifying aggravating activities such as prolonged sitting or running on banked surfaces

Most people improve over several weeks of consistent PT-guided work. Return to full activity is paced to symptoms rather than a fixed calendar.

When should you see a specialist instead of managing at home?

See a physical therapist or primary care clinician if: - Pain has lasted more than two to four weeks without improvement - Symptoms are worsening despite rest and gentle stretching - Weakness, numbness, or pins and needles spread into the foot - You are unsure whether the source is the hip, the piriformis, or the lumbar spine

Clinicians can also rule out less common causes of deep buttock pain, such as hip labral tears, sacroiliac joint dysfunction, or lumbar radiculopathy.
