Back pain and sciatica

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of back pain, including sciatica.

Alternative Names

Herniated disk; Sciatica

Exercise and Physical Therapy

Incorrect movements or long-term high-impact exercise is often a cause of back pain in the first place. People vulnerable to back pain should avoid activities that put undue stress on the lower back or require sudden twisting movements, such as football, golf, ballet, and weight lifting.

Exercise and Acute Back Pain

Exercise does not help acute back pain. In fact, overexertion may cause further harm.

An incremental aerobic exercise program (such as walking, stationary biking, swimming) may begin within 2 weeks of symptoms. Jogging is usually not recommended, at least not until the pain is gone and muscles are stronger.

Patients should avoid exercises that put the lower back under pressure until the back muscles are well toned. Such exercises include leg lifts done in a facedown position, straight leg sit-ups, and leg curls using exercise equipment.

In all cases, patients should never force themselves to exercise if, by doing so, the pain increases.

Exercise and Chronic Back Pain

Exercise plays a very beneficial role in chronic back pain. Repetition is the key to increasing flexibility, building endurance, and strengthening the specific muscles needed to support and neutralize the spine. Exercise should be considered as part of a broader program to return to normal home, work, and social activities. In this way, the positive benefits of exercise not only affect strength and flexibility but they also alter and improve patients' attitudes toward their disability and pain. Exercise may also be effective when combined with a psychological and motivational program, such as cognitive-behavioral therapy.

There are different types of back pain exercises. A 2005 review in the Annals of Internal Medicine found that stretching exercises worked best for reducing pain, while strengthening exercises were best for improving function.

Back pain exercises include:

• Low Impact Aerobic Exercises. Low-impact aerobic exercises, such as swimming, bicycling, and walking, can strengthen muscles in the abdomen and back without over-straining the back. Programs that use strengthening exercises while swimming may be a particularly beneficial approach for many patients with back pain. Medical research has shown that pregnant women who engaged in a water gymnastics program have less back pain and are able to continue working longer.
• Lumbar Extension Strength Training. Exercises called lumbar extension strength training are proving to be effective. Generally, these exercises attempt to strengthen the abdomen, improve lower back mobility, strength, and endurance, and enhance flexibility in the hip and hamstring muscles and tendons at the back of the thigh.
• Yoga, Tai Chi, Chi Kung. Practices originating in Asia that combine low-impact physical movements and meditation may be very helpful. They are designed to achieve a physical and mental balance and can be very helpful in preventing recurrences of low back pain.
• Pilates, an exercise practice that uses yoga principles, may be specifically helpful.
• Flexibility Exercises. Flexibility exercises may help reduce pain. A stretching program may work best when combined with strengthening exercises.
• Retraining Deep Muscles. Some studies suggest a link between low back pain and impaired motor control of deep muscles of the back and trunk. According to these studies, contraction exercises specifically designed to retrain these muscles may be effective for patients with both acute and chronic pain.

Specific Exercises for Low Back Strength Perform the following exercises at least three times a week: Partial Sit-ups. Partial sit-ups or crunches strengthen the abdominal muscles. Keep the knees bent and the lower back flat on the floor while raising the shoulders up three to six inches. Exhale on the way up and inhale on the way down. Perform this exercise slowly eight to ten times with the arms across the chest. Pelvic Tilt. The pelvic tilt alleviates tight or fatigued lower back muscles. Lie on the back with the knees bent and feet flat on the floor. Tighten the buttocks and abdomen so that they tip up slightly. Press the lower back to the floor, hold for one second, and then relax. Be sure to breathe evenly. Over time increase this exercise until it is held for five seconds. Then, extend the legs a little more so that the feet are further away from the body and try it again. Stretching Lower-Back Muscles. The following are three exercises for stretching the lower back: Lie on the back with knees bent and legs together. Keeping arms at the sides, slowly roll the knees over to one side until totally relaxed. Hold this position for about 20 seconds (while breathing evenly) and then repeat on the other side. Lying on the back, hold one knee and pull it gently toward the chest. Hold for 20 seconds. Repeat with the other knee. While supported on hands and knees, lift and straighten right hand and left leg at the same time. Hold for three seconds while tightening the abdominal muscles. The back should be straight. Alternate with the other arm and leg and repeat on each side 8 to 20 times. Note: No one with low back pain should perform exercises that require bending over right after getting up in the morning. At that time, the disks are more fluid-filled and more vulnerable to pressure from this movement.

The Role of Physical Therapy

Physical therapy with a trained professional may be useful if pain has not improved within the first three weeks. It is, in fact, important for any person who has chronic low back pain to have an exercise program guided by professionals who understand the limitations and special needs of back pain and who can address individual health conditions. One study indicated that patients who planned their own exercise did worse than those in physical therapy or doctor-directed programs.

Physical therapy typically includes the following:

• The first stage involves patient education and training the patient in correct movement. Sometimes heat or electro-therapies (such as therapeutic ultrasound or low-energy lasers) are used, although their benefits are unproven.
• If back pain persists beyond 5 weeks, physical therapy is used for rehabilitation. It uses exercises to help the patient keep the spine in neutral positions during all daily activities.
