Abstract

The use of low-power “soft” lasers for the relief of pain has become popular among physiotherapists and acupuncturists, mainly on the strength of uncontrolled anecdotal reports of their efficacy. This review of the available controlled clinical trials suggests that, except in certain specific areas, the role of lasers in the relief of pain is merely that of a powerful placebo.
