If you’ve ever experienced sciatica, you know how debilitating it can be. The sharp, radiating pain that shoots from your lower back down your leg can make even simple movements unbearable.
As a physiotherapist with years of experience treating sciatica patients, I’ve seen firsthand how effective physiotherapy can be in managing and even eliminating this painful condition.
In this guide, I’ll break down everything you need to know about sciatica and how physiotherapy can help. Check out our back and neck services page for more information on how we treat sciatica.
What is Sciatica?
Sciatica isn’t actually a condition itself—it’s a symptom of an underlying issue, usually related to the sciatic nerve, the largest nerve in the body. When this nerve gets compressed or irritated, it can cause pain, tingling, numbness, and weakness that radiate from the lower back down through the buttocks and legs.
The most common causes of sciatica include:
Herniated discs – When the soft cushion between your spine’s vertebrae bulges or ruptures, it can press on the sciatic nerve.
Spinal stenosis – A narrowing of the spinal canal that puts pressure on the nerve roots.
Piriformis syndrome – The piriformis muscle in the buttocks can sometimes spasm and compress the sciatic nerve.
Spondylolisthesis – A slipped vertebra that can pinch the nerve.
Regardless of the cause, sciatica can be incredibly painful and disruptive. That’s where physiotherapy comes in.
How Can Physiotherapy Help Sciatica?
Many people think their only options for sciatica are painkillers or even surgery, but physiotherapy offers a non-invasive, long-term solution that addresses the root cause of the pain rather than just masking it.
Here’s how physiotherapy can help:
1. Pain Relief Techniques
Physiotherapists use several hands-on techniques to relieve pain, including:
Manual therapy – Gentle spinal mobilization or manipulation can help relieve nerve pressure.
Ultrasound therapy – Deep heat therapy can help reduce muscle spasms and inflammation.
TENS (Transcutaneous Electrical Nerve Stimulation) – A small device sends electrical impulses to the affected area, reducing pain signals to the brain.
Many of my patients feel significant relief from these treatments, especially when combined with targeted exercises.
2. Stretching and Mobility Exercises
Tight muscles, especially in the lower back and hips, can contribute to sciatic pain. That’s why stretching is a key part of physiotherapy for sciatica. Some effective stretches include:
Piriformis stretch – Helps relieve pressure on the sciatic nerve.
Hamstring stretch – Loosens tight hamstrings, which can exacerbate lower back issues.
Cat-Cow stretch – Improves spinal flexibility and reduces stiffness.
I’ve had patients who struggled to touch their toes finally regain flexibility and mobility after just a few weeks of consistent stretching.
3. Strengthening Exercises
Weak core muscles can contribute to poor posture and put more strain on the lower back. Strengthening exercises focus on:
Core stability – Exercises like planks help support the lower back.
Glute strengthening – Stronger glutes reduce pressure on the sciatic nerve.
Postural corrections – Learning how to sit and stand properly can prevent further nerve irritation.
I always remind my patients that sciatica relief isn’t just about treating the pain—it’s about preventing it from coming back.
4. Posture and Ergonomic Adjustments
If you spend long hours sitting at a desk or driving, improper posture can make sciatica worse. Physiotherapists can assess your sitting and standing habits and recommend ergonomic improvements, such as:
Using a lumbar support cushion
Keeping feet flat on the ground while sitting
Avoiding prolonged sitting without breaks
One of my patients, saw remarkable improvement after making small changes to his sitting posture and adding regular stretching breaks to his routine.
5. Hydrotherapy (Water-Based Exercises)
Exercising in water is a great option for those who find traditional exercises too painful. The buoyancy of water supports the body and reduces stress on the spine while allowing for effective stretching and strengthening.
How to Get Started with Physiotherapy for Sciatica
If you’re struggling with sciatic pain, here’s what you can do to get started:
Find a qualified physiotherapist – Look for someone experienced in treating sciatica.
Stick with your treatment plan – Improvement takes time, but consistency is key.
Listen to your body – Avoid movements that aggravate your pain.
Stay active – Movement is crucial for recovery, so don’t let fear of pain keep you sedentary.
Final Thoughts:
Is Physiotherapy worth it? Absolutely! Physiotherapy provides long-term relief without the risks of medication or surgery. Whether your sciatica is mild or severe, a good physiotherapy program can help you regain mobility, reduce pain, and prevent future flare-ups.
