Exercise for sciatica from a herniated disc

Leg pain or sciatica from a herniated disc is commonly caused by disc material protruding backwards and irritating or compressing a nerve root, which in turn causes pain to radiate along the sciatic nerve. For more information on herniated discs, please see Overview of lumbar disc herniation.

Exercises to treat sciatica from a herniated disc
Specific exercises for sciatic pain from a herniated disc are prescribed according to which positions will cause the patient’s symptoms to move up the lower extremity and into the low back.

For many patients, getting the pain to move up from the leg to the low back is accomplished by getting into a backwards bending position, called extension exercises or press-ups.

The low back is gently placed into extension by lying on the stomach (prone position) and propping the upper body up on the elbows, keeping hips on the floor (Figure 1). This should be started slowly, since some patients cannot tolerate this position at first.
This position is typically held from five to 30 seconds per repetition, for 10 repetitions.

After practicing this exercise, the spine specialist may recommend a more advanced form of the extension:

From the prone position (lying flat on the stomach), press up on the hands while the pelvis remains in contact with the floor (Figure 2). Keep the lower back and buttocks relaxed for a gentle stretch.
This position is typically held for 1 second, repeated 10 times.

If the patient is unable to lie flat, a similar exercise can be done standing by arching backward slowly with hands on hips (Figure 3). However, the prone position described above is usually preferred.

These extension exercises are done regularly, about every two hours. More importantly, the spine specialist may recommend that the patient with this condition should avoid getting into a forward flexed (bent over) position. This tends to counteract the effects of the extension exercises. The specialist may ask the patient to correct any forward flexed positions immediately by doing an extension exercise.

Advanced sciatica exercises for abdominal muscles and back muscles
As the patient’s pain works out of the lower extremity (leg) and centralizes in the low back, the exercises typically are advanced to strengthen the low back and abdominal muscles to prevent recurrences of sciatic pain caused by a herniated disc.

Low back muscle strengthening exercises:

Upper back extension. In the prone position with hands clasped behind the lower back, raise the head and chest slightly against gravity (Figure 4) while looking at the floor (stay low).
In the prone position with the head and chest lowered to the floor, lightly raise an arm and opposite leg slowly, with the knee locked, 2-3 inches from the floor (Figure 5).

Abdominal muscle strengthening exercises:

Curl-ups. For the upper abdominals, the patient should lie on the back with knees bent, fold arms across the chest, tilt the pelvis to flatten the back, and curl-up lifting the head and shoulders from the floor (Figure 6). Do not attempt to lift too high, and bring the head and chest towards the ceiling. For patients with neck pain, place the hands behind the head.
For the lower abdominals, tighten the lower stomach muscles and slowly raise the straight leg 8 to 12 inches from the floor (Figure 7), keeping the low back held flat against the floor. Water exercises are also excellent to strengthen the lower abdominal muscles, and even just walking in waist-deep water can be helpful.

Other forms of sciatica exercise
Aerobic conditioning may also be encouraged for general body fitness. In general, walking is an excellent form of exercise for the low back because it is relatively low impact but can provide all the benefits of an aerobic workout. If possible, it is best to gradually progress to doing up to three miles of exercise walking at a brisk pace each day.
