Evidence from the small number of placebo-controlled trials does not support the use of transcutaneous electrical nerve stimulation in the routine management of chronic low back pain.36 Evidence from single lower quality trials is insufficient to accurately judge efficacy of transcutaneous electrical nerve stimulation versus other interventions for chronic low back pain or acute low back pain.10
Lumbar radiculopathy: Lumbar radiculopathy is nerve irritation that is caused by damage to the discs between the vertebrae. Damage to the disc occurs because of degeneration ("wear and tear") of the outer ring of the disc, traumatic injury, or both. As a result, the central softer portion of the disc can rupture (herniate) through the outer ring of the disc and abut the spinal cord or its nerves as they exit the bony spinal column. This rupture is what causes the commonly recognized "sciatica" pain of a herniated disc that shoots from the low back and buttock down the leg. Sciatica can be preceded by a history of localized low-back aching or it can follow a "popping" sensation and be accompanied by numbness and tingling. The pain commonly increases with movements at the waist and can increase with coughing or sneezing. In more severe instances, sciatica can be accompanied by incontinence of the bladder and/or bowels. The sciatica of lumbar radiculopathy typically affects only one side of the body, such as the left side or right side, and not both. Lumbar radiculopathy is suspected based on the above symptoms. Increased radiating pain when the lower extremity is lifted supports the diagnosis. Nerve testing (EMG/electromyogramspina bifida
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.
Radicular pain. This type of pain can occur if a spinal nerve root becomes impinged or inflamed. Radicular pain may follow a nerve root pattern or dermatome down into the buttock and/or leg. Its specific sensation is sharp, electric, burning-type pain and can be associated with numbness or weakness (sciatica). It is typically felt on only one side of the body.
If you have an attack of lower-back pain that is severe, continuous and not improving, assessment and treatment by a health care professional who focuses on the back or other musculoskeletal problems may help. These practitioners may use both active and passive techniques to help you feel better. Examples of passive techniques that may be used to get you moving include:
An ancient mind-body practice, meditation has been found to increase pain tolerance and promote management of chronic pain in a number of small studies. In addition, a number of preliminary studies have focused specifically on the use of meditation in the management of low back pain. A 2008 study published in Pain, for example, found that an eight-week meditation program led to an improvement of pain acceptance and physical function in patients with chronic low back pain. The study included 37 older adults, with members meditating an average of 4.3 days a week for an average of 31.6 minutes a day.
Narcotic pain medications. Narcotic medications, also called opioids or painkillers, alter one’s perception of pain by weakening signals sent to the brain. Narcotic medications are most often used for treating intense, short-term pain, such as acute pain after an operation. Narcotics are rarely used to treat long-term pain, as they have many side effects and can easily become addictive.
The mission of the National Institute of Arthritis and Musculoskeletal and Skin Diseases is to support research into the causes, treatment, and prevention of arthritis and musculoskeletal and skin diseases; the training of basic and clinical scientists to carry out this research; and the dissemination of information on research progress in these diseases.
The seated position anatomically means that we don’t engage our abs and glutes, which can result in them switching off and falling asleep. The fall out of this is that other muscles have to work harder to compensate and support the body. The muscles in our lower backs become overworked while our hip flexor muscles mainly the psoas — that attaches to the femur and lumbar spine — become tight and tense. It’s this imbalance that triggers the pain, especially in our lower back.
Acute low back pain is one of the most common reasons for adults to see a family physician. Although most patients recover quickly with minimal treatment, proper evaluation is imperative to identify rare cases of serious underlying pathology. Certain red flags should prompt aggressive treatment or referral to a spine specialist, whereas others are less concerning. Serious red flags include significant trauma related to age (i.e., injury related to a fall from a height or motor vehicle crash in a young patient, or from a minor fall or heavy lifting in a patient with osteoporosis or possible osteoporosis), major or progressive motor or sensory deficit, new-onset bowel or bladder incontinence or urinary retention, loss of anal sphincter tone, saddle anesthesia, history of cancer metastatic to bone, and suspected spinal infection. Without clinical signs of serious pathology, diagnostic imaging and laboratory testing often are not required. Although there are numerous treatments for nonspecific acute low back pain, most have little evidence of benefit. Patient education and medications such as nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants are beneficial. Bed rest should be avoided if possible. Exercises directed by a physical therapist, such as the McKenzie method and spine stabilization exercises, may decrease recurrent pain and need for health care services. Spinal manipulation and chiropractic techniques are no more effective than established medical treatments, and adding them to established treatments does not improve outcomes. No substantial benefit has been shown with oral steroids, acupuncture, massage, traction, lumbar supports, or regular exercise programs.
Research shows that certain forms of magnesium can be effective for pain relief and muscle relaxation, as well as nerve pain. Many people in our society are magnesium deficient, so it may be a good idea to supplement. Magnesium glycinate is known to be a highly bioavailable form. Magnesium citrate can be used by those who tend toward constipation, as it has an additional effect of loosening the bowels.
The presence of any acute nerve dysfunction should also prompt an immediate visit. These would include the inability to walk or inability to raise or lower your foot at the ankle. Also included would be the inability to raise the big toe upward or walk on your heels or stand on your toes. These might indicate an acute nerve injury or compression. Under certain circumstances, this may be an acute neurosurgical emergency.
An accurate history and physical examination are essential for evaluating acute low back pain. Often, patients awaken with morning pain or develop pain after minor forward bending, twisting, or lifting. It is also important to note whether it is a first episode or a recurrent episode. Recurrent episodes usually are more painful with increased symptoms. Red flags are often used to distinguish a common, benign episode from a more significant problem that requires urgent workup and treatment (Table 2).5,6,8 A recent study shows that some red flags are more important than others, and that red flags overall are poor at ruling in more serious causes of low back pain.8 Patients with back pain in the primary care setting (80 percent) tend to have one or more red flags, but rarely have a serious condition.8 However, physicians should be aware of the signs and symptoms of cauda equina syndrome, major intra-abdominal pathology, infections, malignancy, and fractures (Tables 15,6 and 25,6,8). Cauda equina syndrome and infections require immediate referral. Family physicians should rely on a comprehensive clinical approach rather than solely on a checklist of red flags.
Does massage really ease back pain once you leave the table? A recent study found that one weekly massage over a 10 week period improved pain and functioning for people with chronic back pain. Benefits lasted about six months but dwindled after a year. Another hands-on approach is spinal manipulation. Performed by a licensed specialist, this treatment can help relieve structural problems of the spine and restore lost mobility.
