Medications and Alternative Treatments

NO-NSAIDs. NO-NSAIDs are drugs that combine NSAIDs and nitric oxide (NO), a substance that enhances blood flow to the stomach and increases levels of protective mucus and bicarbonate. These agents show particular promise in providing pain relief and reducing the risk for GI problems.

Mind-Body Techniques

According to a 2001 review of studies, only intensive programs that include both psychological and physical rehabilitation therapies were successful in reducing chronic low back pain and improving function. A number of effective approaches to low back pain--called collectively mind-body techniques--employ psychological, behavioral, or physical methods to promote relaxation and reduce stress. Although many may be helpful, evidence is lacking on the specific approaches that would be most successful and which patients would most likely benefit.

Stress Reduction. Stress reducing techniques, including relaxation methods and meditation, may be helpful. One study, for example, reported that meditation was beneficial in reducing pain and improving mood among chronic pain sufferers who had not responded to traditional care. Another found that after three weeks, patients who were in pain after back surgery had less discomfort and slept better after practicing relaxation imagery techniques while listening to music for 25 minutes a day.

Cognitive-Behavioral Therapy. Studies report that a course of cognitive-behavioral therapy helps reduce chronic back pain or at least enhances the patient's ability to deal with it. The primary goal of this form of therapy in such cases is to change the distorted perceptions that patients have of themselves and their approach to pain. Using specific tasks and self-observation, patients gradually shift their fixed ideas that they are helpless against the pain that dominates their lives to the perception that pain is only one negative and, to a degree, a manageable experience among many positive ones. In one study, therapists also taught relaxation techniques and methods to improve posture. The sessions lasted for two and a half hours each week for 12 weeks. More research is needed.

Patient Education and Support Groups. A 2002 study reported that patients with chronic low back pain who participated in an expert-moderated e-mail support and discussion group had less pain and disability after 12 months. An Australian massive public-health campaign that educated patients and doctors about the importance of staying active and dispelled fears about long-term impairment from back pain dramatically reduced disability and worker compensation claims.

Massage Therapy

A number of well-conducted studies have supported the benefits of massage therapy for patients with chronic or acute back pain, especially when it is combined with exercise and patient education. In fact, one analysis in 2003 suggested it may reduce the costs of care. However, it is usually not covered by insurance.

Spinal Manipulation

Spinal Manipulation for Uncomplicated Acute Low Back Pain. Spinal manipulation may be useful for acute back pain that persists beyond 2 to 3 weeks. There are a number of variations, but one example of a spinal manipulation technique is the following:

• The patient first lies on his or her side.
• The practitioner grasps the exposed shoulder and either the hip or knee and then presses the upper and lower portions of the body in opposite directions, so that the torso rotates.
• The shifting vertebrae make a cracking or popping sound, indicating that they have exceeded the normal range of motion.
• Often this results in a greater sense of ease and mobility. (The effect, however, may be temporary.)

Whether on-going manipulations relieve pain better that just one visit is a subject of debate. Some patients consider spinal manipulation to be highly effective for chronic low back pain. A major 2003 analysis, however, reported that current evidence did not support the benefits of spinal manipulation over general medical care or physical therapy for either acute or chronic back pain. (It was better than sham (fake) therapy, however.)

Chiropractic or Osteopathy. Spinal manipulations are typically performed by chiropractors, but osteopathic doctors also perform them.

• One in three people with low back pain seek treatment from a chiropractor. Chiropractic was founded in the U.S. in the late 1800s. The specific goal of chiropractors is to perform spinal manipulations to improve nerve transmission. Many studies have now confirmed that patients feel more satisfied with their chiropractic care than with treatment from general practitioners.
• Osteopathy was also founded in the 1800s. Its core approach to healing also involves physical manipulation. Osteopathy manipulates the bones, muscles, and tendons to optimize blood circulation. The general direction of osteopathy over the years has widened to employ a broader range of treatments that now approach those of standard medicine. One 1999 study reported that osteopathy was as effective as medical treatment in relieving low back pain and patients required far less medication and physical therapy. Osteopathic treatment was also far less expensive than traditional back pain treatments.

Positive Emotional Effects. Both chiropractors and osteopaths offer verbal assurance and a precise treatment regimen. The direct physical connection through spinal manipulation reinforces the patient-practitioner relationship. The emotional effects of such connections may be as important for healing as the treatments themselves.

Side Effects. Mild and temporary side effects from spinal manipulation are common. The potential for serious adverse effects from low back manipulations is low. It should be strongly noted, however, that serious complications (including stroke or spinal cord or neck injury) have been reported with manipulations of the neck. Although little research has been done on such complications, an English survey indicated that they are more frequent than commonly thought.

Some chiropractors may take a lot of x-rays, particularly those of the full spine, which may have long-term harmful consequences. Patients should also be aware that some chiropractors use alternative treatments that have not been proven or rigorously studied. All patients should require objective evidence on the benefits of their treatments.

Other Noninvasive Procedures

Vertebral Axial Decompression. Vertebral axial decompression (VAX-D) may reduce pain and improve function in patients with chronic low back pain, including sciatic pain that radiates down the leg. The patient lies face down on a special table, clutching hand grips and wearing a pelvic harness. The traction-like action alternately decompresses and relaxes the spine over 1-minute intervals. Each session lasts about 30 minutes. Ten to 20 sessions on successive days are often required. The procedure is thought to alleviate pain and enhance healing by relieving pressure within the disks, promoting the in-flow of oxygen, fluids, and nutrients to the spinal column. Some evidence supports its benefits, with reported success rates of around 70%. It is not yet covered by most insurers, however, and more studies are needed to confirm its benefits.

Acupuncture. Acupuncture is now a common alternative treatment for certain kinds of pain. It involves inserting small pins or exerting pressure on certain "energy" points in the body. When the pins have been placed successfully, the patient is supposed to experience a sensation that brings a feeling of fullness, numbness, tingling, and warmth with some soreness around the acupuncture point. Unfortunately, rigorous studies of acupuncture are difficult to perform, and most evidence on its benefits is weak. In any case, it may be specifically helpful for certain patients with back pain, such as pregnant women, who must avoid medications. Anyone who undergoes acupuncture should be sure it is performed in a reputable location by experienced practitioners who use sterilized equipment.

Percutaneous Neuromodulation Therapy. A technique called percutaneous neuromodulation therapy (PNT) uses a small device delivers electrical stimulation to deep tissues and nerve pathways near the spine. It has shown some initial promise for relief of chronic back pain and may also improve mobility and sleep. Treatment sessions are conducted in the doctor's office and last about 30 minutes. A correct pattern of stimulation appears to be important for optimal relief and needs to be determined.

Electric Nerve Stimulation. Transcutaneous electric nerve stimulation (TENS) uses low-level electrical pulses to suppress back pain. A variant, percutaneous electrical nerve stimulation (PENS), applies these pulses through a small needle to acupuncture points. The standard procedure is to give 80 to 100 pulses per second for 45 minutes three times a day. The patients are barely aware of the sensation. Although a 2002 analysis of trials could find no direct evidence of benefit, small studies have reported some relief for chronic low back pain from either TENS or PENS. It is not known if these effects are long lasting. Neither approach is helpful for relief of acute low back pain in most patients.

Muscle Stimulation. Two investigative procedures called automated or electrical twitch obtaining intramuscular stimulation (ATOIMS or ETOIMS) are showing promise. ATOIMS uses an automated mechanical device that vibrates the muscle using a tiny pin. (The sensation is described as similar to a mosquito bite.) ETOIMS uses an extremely mild electrical current. They can also be used together. Both approaches cause the muscles to twitch and then relax then the process is stopped. Discomfort is minimal. Small studies are reporting some help in relieving a number of condition the cause chronic pain, including low back pain.
