Short-term effects of bright light therapy in adults with chronic nonspecific back pain: a randomized controlled trial.

Objective: The present trial evaluated incorporation of bright light therapy in the treatment of chronic nonspecific back pain (CNBP).

Design: A prospective, randomized, controlled, multicenter, open design with three parallel trial arms was used.

Setting: Subjects received a novel therapeutic, an expected therapeutic ineffective low dose, or no light exposure at three different medical centers.

Bright light therapy: Minimizing light induced side effects with an innovative light setup.

Abstract Objective. Bright light therapy (BLT) is regarded to be an effective treatment against seasonal depression (SAD). Conventional BLT devices are reported to evoke few, but inconvenient symptoms.
