In an initial single-arm study, participants with stroke will be tested for OSA and treated with auto-titrating CPAP during inpatient stroke rehabilitation and continued for a 3-month treatment period. Multiple behavioral interventions will be used to improve CPAP use, including intensive CPAP technical support, motivational enhancement therapy, and phone and mobile health automated support. The multicomponent behavioral intervention will be optimized to improve CPAP adherence with the engagement and input of stroke survivors.
