Sciatica: Exercises and Physiotherapy Treatment at Home

What Is Sciatica?

Sciatica refers to pain that travels along the path of the sciatic nerve — from the lower back, through the buttock, and down the back of the leg, sometimes reaching the foot. It's caused by irritation or compression of the sciatic nerve, most commonly from a disc herniation (slipped disc) or spinal stenosis.

Classic symptoms include:

• Shooting or burning pain from lower back into the leg
• Numbness or tingling down the leg or into the foot
• Weakness in the affected leg
• Pain that worsens when sitting, coughing or sneezing
• Difficulty walking or standing for prolonged periods

How Physiotherapy Treats Sciatica

The goals of physiotherapy for sciatica are to reduce nerve irritation, relieve pain, restore movement and prevent recurrence. Most people with sciatica do not require surgery — physiotherapy is the gold standard first-line treatment.

Neural Mobilisation

Gentle nerve gliding exercises help mobilise the sciatic nerve through its pathway, reducing adhesions and sensitivity. These are among the most effective techniques for sciatic pain and are taught during home sessions.

Spinal Decompression Techniques

Specific positions and exercises that reduce pressure on the affected disc or nerve root — providing immediate relief and long-term disc recovery.

Core and Gluteal Strengthening

Strengthening the deep abdominal muscles, hip extensors and gluteal muscles reduces the load on the lumbar spine and protects the nerve from further irritation.

Exercises You Can Try at Home

Important: These exercises are general guidance only. Always consult a physiotherapist before starting any programme, particularly if your symptoms are severe, worsening, or accompanied by bladder/bowel changes.

• Knee-to-chest stretch: Lying on your back, gently draw one knee toward your chest and hold for 20–30 seconds. Repeat 3 times each side.
• Piriformis stretch: Cross the affected leg over the other, then gently pull the knee toward the opposite shoulder until you feel a stretch deep in the buttock.
• Neural floss (sitting): Sitting in a chair, extend the affected leg while flexing your foot — hold 5 seconds, then relax. Repeat 10 times. Caution: if this significantly increases your leg pain, stop and consult a physiotherapist.
• Cat-cow: On hands and knees, alternate between arching and rounding your back slowly. Helps mobilise the lumbar spine and reduce nerve compression.

What to Avoid with Sciatica

• Prolonged sitting, especially in low, soft chairs
• Bending forward with straight legs
• Heavy lifting without proper technique
• Bed rest for extended periods — movement aids recovery

How Long Does Sciatica Last?

Acute sciatica typically improves significantly within 4–8 weeks with appropriate treatment. Persistent or recurring sciatica may take longer and benefits greatly from a structured physiotherapy programme. Early intervention leads to faster resolution and lower risk of chronicity.
