TWILIGHT: Effect of Light Exposure During Acute Rehabilitation on Sleep After Traumatic Brain Injury

This study, led by the University of Washington TBI Model System, aims to improve our understanding how well Brite White Light (BWL) therapy works for treating sleep disruption in people who have experienced a traumatic brain injury and are on an acute inpatient rehabilitation unit setting. Participants are assessed based on sleep efficiency, thinking abilities, therapy participation, and perception of fatigue/sleepiness. In previous studies, dim red light has not had the same effects on function as BWL and is used as the placebo treatment in this study. Each participant is randomized to receive 30 minutes of either BWL therapy or Red Light treatment each morning for 10 days.
