Popis:	OBJECTIVE Post-stroke insomnia is common and negatively impacts stroke recovery. The objective of this study was to determine the effectiveness of bright light therapy as a treatment for early, patients with mild-to-moderate stroke who had post-stroke insomnia. METHODS This study was randomized, double-blind, and placebo-controlled (clinicaltrials.gov ID: NCT04721574). A 2-week trial was conducted in patients with mild-to-moderate stroke who had post-stroke insomnia. Only patients who had experienced a first episode of stroke were enrolled in this study. Sleep parameters were measured using the Actiwatch Spectrum Pro for 7 days before and after light therapy. The instrument specifically collected data concerning sleep, mood state, fatigue and subjective quality of life. Participants with post-stroke insomnia received bright light therapy (10,000-lux) or placebo therapy for 30 minutes in the early morning. A total of 112 eligible participants entered the study, but only 56 patients were randomized to treatment (27 to bright light therapy and 29 to placebo therapy). RESULTS Results from analysis of variance showed that the mean change of sleep latency (F(1, 55) =4.793, P = 0.033) and sleep efficiency (F(1, 55) = 5.625, p = 0.022) were significantly superior in bright light therapy over placebo. Bright light therapy resulted in significant improvements in daytime sleepiness, fatigue, mood, and quality of life in study participants (p < 0.05). CONCLUSION Bright light therapy is a non-pharmacological treatment for early post-stroke insomnia in patients who suffered a mild to moderate stroke. Additionally, bright light therapy is effective to treat daytime sleepiness, fatigue, poor mood, and quality of life in patients with post-stroke insomnia.
