Effects of photobiomodulation therapy associated with motor control exercise for chronic non-specific low back pain: protocol for a randomised placebo-controlled trial.

Photobiomodulation therapy (PBMT), as an adjunct therapy to exercise, can reduce pain in musculoskeletal disorders. In addition, PBMT associated with exercise decreases fatigue, accelerates muscle recovery and enhances performance and gain through different training protocols. Although it has not been investigated, the association of PBMT and exercise therapy could be an alternative to improve the positive effects of exercise in patients with non-specific low back pain (LBP).

Photobiomodulation therapy combined with static magnetic field is better than placebo in patients with fibromyalgia: a randomized placebo-controlled trial.

Background: Fibromyalgia is a syndrome characterized by generalized chronic pain and tenderness in specific areas. Photobiomodulation therapy (PBMT) using low-level laser therapy and/or light emitting diode therapy is an electrophysical agent that can be used alone or together with a static magnetic field (PBMT-sMF) to promote analgesia in several health conditions. Little evidence exists regarding the effects of using PBMT and PBMT-sMF in patients with fibromyalgia; this evidence is conflicting.
