BETHESDA-NIH advisers have declared that an ancient Chinese therapy has a point or two.
A 12-member consensus panel agreed that acupuncture can have limited success as an antiemetic, particularly for chemotherapy, surgery, and morning sickness, and as an analgesic after dental surgery. Therapeutic use should complement Western medicine, not replace it, the panel said.
Though the panels report ruled out virtually none of acupunctures other purported powers, it conceded there were little hard data to prove efficacy for anything else. The gathering was initiated primarily by NIHs Office of Alternative Medicine.
Theres reasonable evidence that needles ease pain from menstrual cramps, tennis elbow, and fibromyalgia, said the panel, chaired by Dr. David Ramsay, president of the University of Maryland School of Medicine. It cited exciting potential areas such as treatment for addiction, carpal tunnel syndrome, osteoarthritis, and headache. Post-stroke rehab also made this list. But theres no point in trying to use needles to quit smoking, it said.
There were two acupuncturists on the panel. Rather than try to prejudice their colleagues, said Penns Dr. Marjorie Bowman, they offered a level of understanding that wasnt always easy to obtain. Admittedly, the panel had to struggle with a dearth of randomized clinical trials and a wealth of small observational studies. Most papers were inadequate to assess efficacy.
Establishing controls for acupuncture is difficult. Using sham needling produces physiological effects. Also, there are 2,000 acupuncture points, and practitioners often disagree on which to choose. -Anne S. Harding
