Randomized Controlled Trial Multicenter Study
Short-term effects of bright light therapy in adults with chronic nonspecific back pain: a randomized controlled trial.
The present trial evaluated incorporation of bright light therapy in the treatment of chronic nonspecific back pain (CNBP). ⋯ The present randomized controlled trial shows that light therapy even in low dose could improve depressive symptoms and reduce pain intensity in CNBP patients. Further research is needed for optimizing parameters of frequency, dose, and duration of therapeutic light exposure.
