Insufficient evidence for laser therapy in treating low back pain

A high-profile study on laser therapy and lower back pain concluded that there is insufficient evidence to support the use of light therapy for decreasing pain intensity and disability in people with acute, subacute, and chronic non-specific low back pain. The study utilized a triple-blinding technique and followed up with patients for up to a year. However, the researchers used a laser device that did not deliver enough power and utilized the wrong color of light, contradicting the recommended guidelines for laser therapy dosages. Therefore, the conclusion that laser therapy does not work for low back pain can be attributed to the specific device used, rather than the therapy as a whole.
