In chronic low back pain, low level laser therapy combined with exercise is more beneficial than exercise alone in the long term: a randomized trial

The authors of this study set out to determine if Low-Level Laser Therapy (LLLT) could be an effective adjuvant intervention for chronic low back pain. The researchers had three test groups with chronic low back pain. Group one received only LLLT, group two received LLLT and an exercise program, and group three received only exercise and a placebo (fake) laser. The scientists concluded: “In chronic low back pain, LLLT combined with exercise is more beneficial than exercise alone in the long term.”
