Dosage Matters.

ABSTRACT: Background and Purpose- For stroke rehabilitation, task-specific training in animal models and human rehabilitation trials is considered important to modulate neuroplasticity, promote motor learning, and functional recovery. Little is known about what constitutes an effective dosage of therapy. Methods- This is a parallel group, 4 arms, single-blind, phase IIb, randomized controlled trial of 4 dosages of arm therapy delivered in an outpatient setting chronically after stroke. Participants were randomized into groups that varied in duration of scheduled therapy (ie, 0, 15, 30, or 60 hours). Forty-one participants completed the study. Planned primary analyses used linear mixed effects regression to model changes from baseline to postintervention in the Motor Activity Log-Quality of Movement
