BackgroundConstraint-induced movement therapy (CI therapy) is one of few treatments for upper extremity (UE) hemiparesis that has been shown to result in motor recovery and improved quality of life in chronic stroke. However, the extent to which treatment-induced improvements in motor function versus daily use of the more affected arm independently contribute to improved quality of life remains largely unexplored.ObjectiveThe objective of this study is to identify whether motor function or daily use of a hemiparetic arm has a greater influence on quality of life after CI therapy.MethodsTwo cohorts of participants with chronic stroke received either in-person CI therapy (n = 29) or video-game home-based CI therapy (n = 16). The two cohorts were combined and the motor-related outcomes (Wolf Motor Function Test, Action Research Arm Test, Motor Activity Log [MAL]) and quality of life (Stroke-Specific Quality of Life) were jointly modeled to assess the associations between outcomes.ResultsThe only outcome associated with improved quality of life was the MAL. Improvements in quality of life were not restricted to motor domains, but generalized to psychosocial domains as well.ConclusionsResults suggest that improved arm use during everyday activities is integral to maximizing quality of life gains during motor rehabilitation for chronic post-stroke UE hemiparesis. In contrast, gains in motor function were not associated with increases in quality of life. These findings further support the need to implement techniques into clinical practice that promote arm use during daily life if improving quality of life is a main goal of treatment.
