What You Can Expect
On your first visit to an acupuncturist, the practitioner will take a thorough medical history, then may assess three pulses on each wrist, examine your tongue, take note of how your breath and body smell, and "palpate" (or feel) certain areas of your body. Depending on your ailment, you may also have your first acupuncture treatment at this time. In general, visits occur once or twice a week over several months until therapeutic results are achieved.
While the needles can feel uncomfortable at times, they rarely hurt. They are very thin (only about three times the thickness of a human hair and much finer than the hypodermic needles used to give injections) and are designed to enter the skin with little resistance. Once the needles are inserted (generally from one to 15 are used), the acupuncturist may twist them manually or send a weak electrical current through them to increase the energy flow. The needles may be left in for 15 to 40 minutes, depending on the ailment. Some practitioners also use moxibustion, which involves heating the needles or acupoint with a slowly burning herbal agent (primarily the dried Herb mugwort) to hasten healing.
Different people experience different sensations from acupuncture. Some describe a tingling pins-and-needles feeling, others may feel numbness or nothing at all. Most find the sessions relaxing, and many fall asleep during or immediately after treatment.
Some patients notice rapid improvement after just a few sessions. In those whose conditions have taken years to develop, treatment may take longer.
Health Benefits
While scores of illnesses have traditionally been treated by acupuncture in Asia, its primary use in the United States has been to relieve chronic pain--caused by such ailments as arthritis, headache, PMS, and back pain--and to assist withdrawal from addictions such as drug and alcohol dependency. Today more innovative applications for acupuncture are being explored by both conventional and alternative practitioners, including its use as an analgesic to reduce pain during surgery.
In 1997, an advisory panel for the National Institutes of Health (NIH) evaluated hundreds of acupuncture studies and concluded that the therapy is an effective treatment for postoperative pain after dental surgery and for nausea induced by chemotherapy, pregnancy ("morning sickness"), and anesthesia. Today scientists are studying acupuncture’s effects on everything from back pain, to breech birth, to irritable bowel syndrome. It seems that the practical applications of this therapy are expanding everyday.
Doctors are often have very little to offer patients undergoing stroke rehabilitation therapy. Research is now beginning to examine how acupuncture may be able to benefit these difficult cases. Preliminary data shows that acupuncture may be more beneficial than control interventions, and may also useful as an adjunct to conventional stroke rehabilitation treatment (1, 2). However, this research still has a long way to go to be able to garner reliable results. More studies with higher quality research design are needed to fully validate these effects.
There exists a mounting body of evidence for the use of acupuncture in the treatment of chronic pain. A criterion-based review of 51 controlled trials of acupuncture for the treatment of chronic pain found 24 trials reporting results favoring acupuncture (3). However, most of these studies showed conflicting results or were of small size or low quality. More research is necessary to distinguish the possible benefits of acupuncture for chronic pain conditions. Other studies of auricular acupuncture for cancer pain, for chronic epicondylitis, for chronic neck pain, and for back pain show that acupuncture may be of benefit (4-8).
A small trial conducted by researchers in Norway found that acupuncture treatment reduced chronic neck and shoulder pain up to three years after the last treatment was administered (9). Further research is needed to validate these findings and assess the number of treatments needed to instill long term benefits.
Acupuncture is also being investigated as a useful therapy for the treatment of osteoarthritis. Nearly 21 million people in the U.S. alone are plagued by this debilitating condition. Currently many studies are seeking to determine if acupuncture is beneficial in relieving the pain and disability caused by this degenerative condition. As with other conditions, study results on the effectiveness of acupuncture for osteoarthritis are not consistent. A systematic review including seven trials of acupuncture for knee osteoarthritis failed to show a beneficial effect greater than Placebo (10). However, these studies were of varying quality, duration, and size. Other studies show acupuncture to be a useful adjunct to drug therapy (11). Recent smaller trials suggest that acupuncture for osteoarthritis of the knee can bring significant pain and symptom relief either alone or as an adjunctive therapy (12).
In the largest scale trial of acupuncture for osteoarthritis to date, researchers at the University of Maryland Baltimore recently demonstrated that acupuncture for osteoarthritis of the knee is both safe and effective (13). In their study published in the Annals of Internal Medicine, the research team compared the efficacy of true acupuncture, to sham acupuncture, and patient education. At twenty-six weeks the true acupuncture group showed significant improvements over the other conditions on measures of pain, function, and global improvement.
A quickly expanding body of evidence also supports the use of acupuncture in the treatment of chronic headaches. A study conducted on 401 patients being treated by their family doctor for migraine, or tension type headaches found that the patients who received acupuncture showed persistent clinical benefits that lead to a better quality of life, when compared to the non-acupuncture group (14).
