Piriformis syndrome physiotherapy may help if you experience deep buttock pain, leg symptoms, or discomfort that worsens with sitting. This condition can feel similar to sciatica, which is why careful assessment matters.

Piriformis syndrome occurs when the piriformis muscle, a deep hip rotator, irritates the nearby sciatic nerve. Symptoms can overlap with other causes of hip pain and sacroiliac joint (SIJ) pain, so accurate diagnosis is essential.

For a medical overview, see the NCBI StatPearls summary on piriformis syndrome.

Piriformis syndrome physiotherapy

The piriformis muscle sits deep in the buttock and helps control hip rotation and pelvic stability during walking, running, and sitting. When this muscle becomes overloaded, tight, or irritated, it can compress or sensitise the sciatic nerve, leading to buttock pain and nerve-related symptoms down the leg.

Piriformis syndrome is often a diagnosis of exclusion. This means your physiotherapist may also assess other potential sources of symptoms, including lumbar spine or SIJ-related pain.

Common symptoms

• Deep buttock pain, often on one side
• Pain that worsens with prolonged sitting
• Tingling, burning, or numbness down the back of the thigh
• Discomfort when climbing stairs or rising from sitting
• Tenderness when pressing over the buttock region

What causes piriformis syndrome?

Piriformis syndrome usually develops due to a combination of load, posture, and movement factors rather than a single cause. Contributing factors may include:

• Prolonged sitting or repetitive hip loading
• Sudden increases in training or activity
• Reduced pelvic and trunk control
• Gluteal weakness or delayed activation
• Altered walking or running mechanics

It can overlap with conditions such as Greater Trochanteric Pain Syndrome (GTPS) or gluteal tendinopathy.

The role of core and hip control

Piriformis symptoms rarely occur in isolation. Reduced deep core control may affect pelvic stability and load distribution through the hip. Over time, this can increase strain on the deep hip rotators, including the piriformis.

Rehabilitation often includes improving deep core muscle activation and restoring strength and endurance of the deep hip rotators. Core stability may also be addressed where pelvic control is contributing.

Can piriformis syndrome cause sciatica-like pain?

Yes. Piriformis syndrome can irritate the sciatic nerve and produce symptoms that feel similar to sciatica originating from the spine. The source of irritation differs, which is why assessment matters before deciding on treatment.

How is piriformis syndrome diagnosed?

Diagnosis is based on a detailed clinical assessment. A physiotherapist will assess hip movement, pelvic control, nerve sensitivity, and symptom reproduction with specific tests.

Imaging such as MRI may be used when symptoms persist or when other conditions need to be excluded, but it is not always required.

Piriformis syndrome treatment options

Management focuses on reducing nerve irritation, restoring movement control, and improving tolerance to sitting and activity. Treatment may include:

• Physiotherapy: targeted exercise for hip control and glute strength
• Activity modification: adjusting sitting habits and training load
• Manual therapy: hands-on techniques to reduce sensitivity
• Heat or ice: short-term symptom relief
• Education: identifying triggers and pacing activity

Recovery and long-term management

• Gradual return to sitting tolerance
• Progressive strengthening of hips and trunk
• Maintaining movement variety
• Addressing contributing control factors

What to do if buttock pain keeps returning

Recurring buttock pain often reflects unresolved load or movement issues. A physiotherapist can assess contributing factors and guide appropriate exercise progressions.
