Sciatica is one of the most painful and most mismanaged nerve conditions. That sharp, electric, or burning sensation running from the lower back through the buttock and down the leg affects many people who might not know the best way to relieve it.
This article covers the exercises that are most commonly effective for sciatica, when each is appropriate, and what to avoid.
What Is Sciatica and Why Does It Happen?
The sciatic nerve is the longest and widest nerve in the body. It is formed from nerve roots at the L4, L5, S1, S2, and S3 levels of the lumbar spine, merges into a single nerve in the buttock, and travels down the back of the thigh before dividing into branches that supply the lower leg and foot. When any part of this nerve or its contributing nerve roots is compressed or irritated, the symptoms that result are collectively called sciatica.
Sciatica describes pain, numbness, tingling, or weakness following the path of the sciatic nerve but the cause of that nerve irritation can be several different things.
- The most common cause is a lumbar disc herniation, where the inner material of an intervertebral disc pushes through the outer wall and presses on a nearby nerve root.
- Lumbar spinal stenosis, where narrowing of the spinal canal that reduces the space available for the nerve roots, is another common cause, particularly in older adults.
- Piriformis syndrome involves the piriformis muscle in the deep buttock irritating the sciatic nerve as it passes through or beneath it.
- Spondylolisthesis, where one vertebra slips forward over the one below, can also narrow the nerve exit and produce sciatic symptoms.
Movements that arch the lumbar spine backward help many cases of disc-related sciatica by encouraging the disc material to move away from the nerve root. The same exercises can worsen stenosis-related sciatica by further narrowing an already reduced canal space.
Movements that curl the spine forward often help stenosis by opening the posterior canal, but can increase disc pressure and worsen disc-related sciatica. That’s why choosing the right type of exercise is important.
Exercises for Sciatica Nerve Pain
Extension-Based Exercises — For Disc-Related Sciatica
These exercises are most appropriate when sciatica is caused by a lumbar disc herniation, symptoms are worse with sitting and forward bending, and extension or lying flat provides relief. If extension movements consistently increase leg symptoms, these exercises are not appropriate and flexion-based or neural mobilisation exercises should be tried instead.
Prone lying
Lie face down with the arms at the sides and the body completely relaxed. Hold for two to five minutes. Do this several times daily, particularly after prolonged sitting
Prone press-up
Lie face down with hands placed flat on the floor under the shoulders, as in the top position of a push-up. Slowly push the upper body upward by straightening the arms, keeping the pelvis and legs relaxed on the floor — the lower back should arch, not the upper back. Hold at the top for one to two seconds and lower slowly. Do ten repetitions, three to four times daily.
Standing lumbar extension
Stand with feet shoulder-width apart and place both hands on the lower back just above the pelvis. Gently arch backward, keeping the knees straight, until a mild extension is felt in the lower back. Hold for two seconds. Repeat ten times.
Flexion-Based Exercises — For Stenosis-Related Sciatica
These exercises are most appropriate when sciatica is caused by lumbar spinal stenosis, symptoms are worse with standing and walking, and leaning forward provides relief. If flexion movements consistently increase leg symptoms, these exercises are not appropriate.
Knee to chest stretch
Lying on the back with both knees bent, bring one knee toward the chest and hold gently behind the thigh or shin. Hold for 30 seconds, then switch sides. Repeat three times on each side. Progress to bringing both knees to the chest simultaneously and holding for 30 seconds. Do this twice daily.
Seated lumbar flexion
Sit on a sturdy chair with feet flat on the floor and knees apart. Slowly lean forward, letting the upper body drop down between the knees toward the floor. Allow the spine to round fully. Hold for 20 to 30 seconds and return slowly to upright. Repeat three to five times.
Child’s pose
Begin kneeling on the floor, then sit the hips back toward the heels and reach the arms forward along the floor. Allow the spine to round and the forehead to rest on the floor or a folded towel. Hold for 30 to 60 seconds, repeat three times. Perform once or twice daily.
Neural Mobilisation — Sciatic Nerve Glides and Flossing
These exercises should produce a mild pulling sensation along the back of the thigh or leg. They should not produce sharp pain or a significant increase in leg symptoms. If they do, the range needs to be reduced.
Sciatic nerve floss, seated
Sit upright on a chair with the feet flat on the floor. Slowly straighten one knee, extending the leg forward, while simultaneously pulling the toes toward you. Hold for two seconds at the end of the movement, then relax both the knee and the foot back to the starting position. Repeat ten to fifteen times on each side, once or twice daily.
Sciatic nerve floss, lying
Lie on the back with both knees bent and feet flat on the floor. Slowly straighten one knee, lifting the leg toward the ceiling, then bend it back down. Repeat ten to fifteen times. Once this is comfortable, pull the toes toward you as the knee straightens.
Slump stretch
Sit on a chair and allow the spine to slump forward into full flexion — rounding the back and dropping the head. From this position, slowly extend one knee and pull the toes toward you. Hold for two to three seconds and release. Repeat ten times on each side. The slump position adds cervical and thoracic neural tension to the sciatic mobilisation, producing a more comprehensive neural stretch.
What to Avoid: Exercises That Can Worsen Sciatica
Straight leg raises
Straight leg raises in the acute phase place the sciatic nerve under significant tension — the movement stretches the nerve along its full length when it is already highly sensitised.
Sit-ups and crunches
Sit-ups and crunches increase intradiscal pressure considerably and can worsen disc-related sciatica significantly. The lumbar flexion combined with loading that these exercises produce is one of the least appropriate movement patterns for an irritated disc.
Heavy deadlifts and squats
Heavy deadlifts and squats are inappropriate until core stability gets stronger, nerve sensitivity is reduced, and the movements can be performed correctly. In the acute and early sub-acute phase, these exercises load the lumbar spine under conditions it cannot currently handle safely.
Hamstring stretching
The sciatic nerve runs in close proximity to the hamstring muscles, and aggressive hamstring stretching places the nerve under tension that provokes rather than relieves symptoms.
How Physiotherapy Treats Sciatica Beyond Exercise
Exercise is the most important component of sciatica rehabilitation, but physiotherapy provides additional tools that significantly accelerate recovery and that cannot be replicated at home.
Accurate assessment identifies the specific cause of the sciatica, the nerve root level involved, the direction of preference that determines which exercises are appropriate, and the contributing factors that need to be addressed alongside symptom management.
Manual Therapy
Manual therapy through joint mobilisation of the lumbar and thoracic spine restores movement that pain and guarding have restricted, reduces the muscle spasm that compounds nerve root irritation, and improves the mechanics of the lumbar spine in ways that exercise alone cannot achieve in the early stages.
Neural Mobilisation
Neural mobilisation performed by a physiotherapist is more specific and more targeted. These techniques can be adjusted to the level of nerve sensitivity, make progress as that sensitivity reduces, and combined with manual therapy in ways that produce faster nerve recovery than exercise alone.
How Long Does Sciatica Take to Resolve With Exercise?
Senaman-senaman berikut disusun mengikut punca kebas tangan yang paling biasa berlaku. Setiap senaman sepatutnya hanya menimbulkan sensasi tarikan atau regangan yang ringan. Sebarang senaman yang meningkatkan rasa kebas, dicucuk-cucuk, atau kesakitan semasa atau selepasnya perlu dihentikan dan tekniknya hendaklah dinilai semula.
Bagi Sindrom Terowong Karpal
Most acute sciatica episodes improve significantly within six to twelve weeks of appropriate management.
Nerve symptoms like numbness and tingling typically persist longer than pain, often remaining for several weeks after pain has settled. This is normal and reflects the slower rate of nerve recovery compared to muscle or joint tissue. Weakness, when present, is the slowest symptom to resolve and in significant cases may take months to fully recover.
Chronic sciatica that has been present for months or years takes longer to resolve than acute presentations but still responds well to the right approach.
