S-adenosylmethionine (SAMe). S-adenosylmethionine (SAMe, pronounced "Sammy") is a synthetic form of a natural byproduct of the amino acid methionine. It has been marketed as a remedy for both depression and arthritis. Some research suggests that it may work as well as NSAIDs for short-term treatment of osteoarthritis. Other studies suggest that it may help rebuild damaged cartilage.
Herbs and SupplementsGenerally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been several reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements. |
Acupuncture
Acupuncture is increasingly being used to reduce osteoarthritis pain. The technique is painless and involves the insertion of small fine needles at select points in the body. Several study reviews have found that acupuncture provides at least short-term pain relief for osteoarthritis of the knee. Other studies have suggested that acupuncture’s benefits are mainly due to a strong placebo effect. In 2004, researchers published results from an important clinical trial that studied the effects of acupuncture on nearly 600 people with osteoarthritis of the knee. The results indicated that acupuncture can relieve pain and improve function. In any case, acupuncture may be a safe and beneficial addition to standard therapy for certain patients, such as pregnant women, who cannot take most pain medications.
Transcutaneous Electric Nerve Stimulation
Transcutaneous electric nerve stimulation (TENS) uses low-level electrical pulses to suppress pain. Patients are barely aware of the sensation. According to one study, the optimal treatment length is 40 minutes. A variant (sometimes called percutaneous electrical nerve stimulation, or PENS) applies these pulses through a small needle to acupuncture points. A review of trials reported that both methods were better than placebo (sham treatments) in treating osteoarthritis of the knee, although additional well-designed studies are needed.
Low-Level Laser Therapy
Low-level laser therapy (LLLT) generates extremely pure light in a single wavelength. It does not produce heat and is painless. Some researchers are combining LLLT with transcutaneous electric nerve stimulation (TENS). Studies report widely varying results, with some showing significant reductions in pain and others reporting no effect. The differences may be due to different approaches, and standardized methods are needed to determine any benefits.
Hydrotherapy
Hydrotherapy, also called spa therapy or balneotherapy, is an ancient therapy that uses bathing in mineral baths for soothing pain. Although many studies report positive results, including improved quality of life, very few have been rigorously conducted. A major analysis reported weak evidence on any real effect on pain or quality of life, but some patients may find comfort from this pleasant therapy.
