P102 Sleep Quality, Depression, and Anxiety in People with Spinal Cord Injury and Traumatic Brain Injury Undergoing Inpatient Rehabilitation.

INTRODUCTION: Poor sleep, depression, and anxiety are prevalent secondary complications of spinal cord injury (SCI) and traumatic brain injury (TBI), and may interfere with recovery. This observational, exploratory study aimed to describe subjective and objective sleep quality, and levels of depression and anxiety in people with SCI and TBI undergoing inpatient rehabilitation; and to explore associations between sleep quality, depression, and anxiety. METHODS: Twenty-four patients admitted to two neurorehabilitation facilities following SCI (n =18) or TBI (n = 6) completed the Pittsburgh Sleep Quality Index, the Depression, Anxiety, and Stress Scale-21, and one week of actigraphy monitoring. RESULTS: Most participants reported poor subjective sleep quality (83%). Average depression and anxiety scores were within normal levels. Higher anxiety scores correlated with lower subjective sleep quality, longer sleep onset latency, and lower subjective total sleep time. DISCUSSION: The findings suggest that targeting anxiety may improve sleep quality in inpatients with SCI or TBI, and vice-versa. Longitudinal and interventional studies are required to understand whether these relationships are reciprocal, and whether therapies targeting both sleep and mental health during inpatient rehabilitation can improve patient outcomes.
