Insufficient evidence for laser therapy in low back pain

A systematic literature review found insufficient evidence to support the use of laser therapy for reducing pain and disability in people with nonspecific low back pain. Despite the recommendation by the American College of Physicians, the review concluded that laser therapy did not provide significant benefits based on three randomized controlled trials. Several previous systematic reviews were excluded from this review, as they included different types of laser therapy not considered as photobiomodulation therapy. The review's conclusion was based on the exclusion of class IV lasers and the limited evidence supporting the use of laser therapy for low back pain.
