<>Transcutaneous electric nerve stimulation (TENS): TENS provides pulses of electrical stimulation through surface electrodes. For acute back pain, there is no proven benefit. Two small studies produced inconclusive results, with a trend toward improvement with TENS. In chronic back pain, there is conflicting evidence regarding its ability to help relieve pain. One study showed a slight advantage at one week for TENS but no difference at three months and beyond. Other studies showed no benefit for TENS at any time. There is no known benefit for sciatica. >
<>Limited bed rest. Once the mainstay of treatment for back pain, bed rest has fallen out of favor. Doctors now know it's better to keep moving, so that your muscles don't become stiff. Bed rest can still be useful relief from low back pain, particularly if your pain is so severe that it hurts to sit or stand. But try to limit it to a few hours at a time and for no more than one or two days. >
<>The prevention of back pain is, itself, somewhat controversial. It has long been thought that exercise and an all-around healthy lifestyle would prevent back pain. This is not necessarily true. In fact, several studies have found that the wrong type of exercise such as high-impact activities may increase the chance of suffering back pain. Nonetheless, exercise is important for overall health and should not be avoided. Low-impact activities such as swimming, walking, and bicycling can increase overall fitness without straining the low back. >
<>“For most people, it means their back hurts,” says Richard A. Deyo, MD, MPH,the Kaiser-Permanente Endowed Professor of Evidence-Based Medicine in the department of family medicine at Oregon Health & Science University in Portland. “But it’s often impossible to know the precise anatomical cause of back pain because the back has so many sources of pain.” >
<>Sports that have higher rates of back pain include gymnastics, diving, weight lifting, golf, American football, and rowing.61 In gymnastics, the incidence of back injuries is 11%. In football linemen, it may be as high as 50%.18 Ninety percent of all injuries of professional golfers involve the neck or back.19 Injury rates for 15- and 16-year-old girls in gymnastics, dance, or gym training are higher than the general population, while cross-country skiing and aerobics are associated with a lower prevalence of low back pain.4 For boys, volleyball, gymnastics, weight lifting, downhill skiing, and snowboarding are associated with higher prevalence of low back pain, while cross-country skiing and aerobics show a lower prevalence. >
<>To understand various causes of low back pain, it is important to appreciate the normal design (anatomy) of the tissues of this area of the body. Important structures of the low back that can be related to symptoms in this region include the bony lumbar spine (vertebrae, singular = vertebra), discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of the low back, internal organs of the pelvis and abdomen, and the skin covering the lumbar area. >
<>Physical Therapy. Physical therapists often recommend the McKenzie method or spine stabilization exercises for the treatment of low back pain. The McKenzie method is described at http://www.mckenziemdt.org/approach.cfm, and a video demonstration is available at http://www.youtube.com/watch?v=wBOp-ugJbTQ. The McKenzie method has been shown to be slightly more effective than other common low back pain treatments; however, the difference is not clinically significant,26,27 and evidence on its effect on disability is conflicting.26,27 There also do not appear to be good long-term benefits with the McKenzie method, other than decreased need for health care services.27 Spine stabilization exercises have been shown to decrease pain, disability, and risk of recurrence after a first episode of back pain.28 >
<>Pregnancy commonly leads to low back pain by mechanically stressing the lumbar spine (changing the normal lumbar curvature) and by the positioning of the baby inside of the abdomen. Additionally, the effects of the female hormone estrogen and the ligament-loosening hormone relaxin may contribute to loosening of the ligaments and structures of the back. Pelvic-tilt exercises and stretches are often recommended for relieving this pain. Women are also recommended to maintain physical conditioning during pregnancy according to their doctors' advice. Natural labor can also cause low back pain. >
<>Nerve root syndromes are those that produce symptoms of nerve impingement (a nerve is directly irritated), often due to a herniation (or bulging) of the disc between the lower back bones. Sciatica is an example of nerve root impingement. Impingement pain tends to be sharp, affecting a specific area, and associated with numbness in the area of the leg that the affected nerve supplies. >
<>Some people may need prescription-strength NSAIDs or opioid medications to help with pain. It is important to talk to your doctor or pharmacist if you are taking any other medications -- including over-the-counter medicines -- to avoid overdosing on certain active ingredients. Your doctor may also prescribe muscle relaxants to help ease painful muscle spasms. >
