The proposed study aims to characterize the proportion of people with stroke that have non-OSA sleep disorders and their impact on recovery of activities of daily living, functional mobility, and participation along the continuum of recovery in people with stroke.', 'detailedDescription': 'The overall goal in this project is to develop an in-depth understanding of the complex interplay between non-obstructive sleep apnea (non OSA) sleep disorders and recovery after stroke. Sleep is vital to overall health and quality of life. Abnormal or insufficient sleep is both a risk factor and consequence of stroke. Sleep also plays a critical role in motor learning, which is the foundation of rehabilitation strategies after stroke. Although there is a growing understanding of the interplay between sleep, stroke, and recovery in people with OSA these complex relationships in individuals post stroke with non OSA sleep disorders are not well understood. In order to develop targeted sleep interventions to support rehabilitation after stroke and promote optimal recovery, it is critical to gain a fuller understanding of the prevalence and impact of non OSA sleep disorders in people with stroke across the continuum of recovery. The specific objectives of this proposal will lay the necessary groundwork for this as investigators will characterize the proportion of people with stroke that have insomnia disorders, restless legs syndrome, and insufficient sleep; and evaluate the impact of these non OSA sleep disorders on recovery of activities of daily living, mobility/activity, and participation across the continuum of recovery after stroke. The study will take an innovative approach to measuring sleep, mobility/activity, and participation using a combination of techniques across the measurement spectrum that will include self-report questionnaires, clinic-based measures of capacity, and body worn sensors. The body worn sensors will include actigraphy to measure sleep parameters, activity monitors to measure mobility/activity levels, and Global Positioning System (GPS) units to measure participation. Additionally, investigators will apply innovative, big data tools from topological data analysis for a data driven approach to discover complex, structural, non-linear interdependent relationships among stroke, sleep, and recovery of mobility/activity, and participation. Upon completion of this study there will be an understanding of the prevalence and impact of non-OSA sleep disorders on recovery of function, mobility/activity, and participation across the continuum of recovery post stroke. This is an important, necessary step to develop appropriate sleep-based interventions to complement targeted rehabilitation strategies to enhance the health and quality of life in people with stroke.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Adults recovering from stroke within the first 90 days following stroke who did not have a diagnosis of obstructive sleep apnea (OSA) prior to stroke or who do not have oxygen desaturation index (ODI) of 15 or higher during inpatient rehabilitation (\\~15 days post-stroke).', 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Diagnosis of stroke as defined by the WHO: "a rapid onset event of vascular origin reflecting a focal disturbance of cerebral function, excluding isolated impairments of higher function and persisting longer than 24 hours."
