Sciatica

Sciatica refers to pain that radiates along the path of the sciatic nerve, typically running from the lower back through the hip and down the leg. It can cause significant discomfort and limit daily activities. Physiotherapy plays a central role in relieving sciatic pain, reducing nerve irritation, and restoring normal movement and function.

What is Sciatica?

Sciatica occurs when the sciatic nerve, the longest nerve in the body, becomes compressed or irritated, most often due to a disc prolapse, spinal stenosis, or muscle tightness in the lower back or buttock region. Rather than a condition itself, sciatica is a symptom of an underlying issue affecting the nerve as it travels from the lower spine down the leg.

Common Causes of Sciatica

• Herniated or bulging disc (PIVD) pressing on the nerve root.
• Spinal stenosis narrowing the space around the nerve.
• Piriformis syndrome, where a tight buttock muscle irritates the nerve.
• Degenerative changes in the spine, such as spondylosis.
• Spondylolisthesis (slipped vertebra).
• Prolonged poor posture or sitting habits.

Common Symptoms

• Sharp, shooting, or burning pain radiating from the lower back through the buttock and down the leg.
• Numbness or tingling along the path of the sciatic nerve.
• Muscle weakness in the leg or foot.
• Pain that worsens with sitting, bending, or coughing.
• Difficulty standing up straight or walking comfortably.
• Symptoms typically affecting one side of the body.

Goals of Physiotherapy for Sciatica

• Reduce nerve irritation and associated pain.
• Relieve muscle tightness contributing to nerve compression.
• Improve spinal and hip mobility.
• Strengthen core and postural muscles to reduce strain on the lower back.
• Correct posture and movement patterns that aggravate the nerve.
• Prevent recurrence and support long-term relief.

Physiotherapy Techniques Used

• Nerve mobilization (nerve gliding) exercises – gentle techniques to ease nerve irritation and improve nerve mobility.
• Manual therapy – hands-on techniques to relieve muscle tightness and spinal stiffness.
• Core stabilization exercises – to build muscular support and reduce pressure on the lower back and nerve.
• Stretching exercises – targeting the lower back, hip, and piriformis muscles.
• Electrotherapy – such as TENS and ultrasound for pain relief.
• Postural correction – guidance on sitting, standing, and lifting to reduce nerve strain.
• Activity modification – advice on positions and movements to avoid during acute flare-ups.

When to Seek Further Medical Evaluation

While most sciatica cases improve with physiotherapy and conservative care, symptoms such as progressive leg weakness, loss of bladder or bowel control, or severe unrelenting pain require prompt medical evaluation, as they may indicate significant nerve compression needing urgent attention. Physiotherapists coordinate closely with treating physicians when such signs are present.

Through targeted nerve mobilization, strengthening, and postural correction, physiotherapy offers effective relief from sciatica, helping patients reduce pain, restore mobility, and prevent future flare-ups.
