To the Editor Dr Hinman and colleagues1 presented a generally well-conducted trial of the effectiveness of acupuncture treatment (stimulation using laser or needles) for pain and function in knee osteoarthritis. However, the authors failed to find any benefit of acupuncture, which is not a surprising outcome—at least for laser acupuncture—given the laser acupuncture treatment parameters used in the trial. These parameters were well below those that are considered necessary to provide a therapeutic benefit, particularly in terms of the dosage and power outputs used.
