Although empirical evidence shows that dyad learning leads to superior outcomes compared to physical practice alone when learning complex motor tasks, it has not been established as a rehabilitation tool. This study aims to determine the effects of dyad learning on motor performance in a wrist-robotic environment to evaluate its potential use in rehabilitation. Methods: Forty-two participants were randomized into three groups (N=14): Dyad learning, physical practice and control. Participants practiced a 2 degree-of-freedom gamified motor task for 20 trials using a custom made wrist-robotic device. Motor performance was measured at baseline, the end of training, and 24 hour retention. Results: Motor performance did not differ between groups at baseline and all groups improved their performance compared to baseline (p<0.05). However, the dyad group outperformed the other groups at the end of training (p=0.001; Cohen’s d=0.954) and at retention (p=0.012; d=0.617). Conclusion: Compared to physical practice alone, practicing collaboratively by alternating between physical and observational practice leads to superior motor outcomes after practicing a robot-aided gamified motor task. Dyad learning may be a valuable tool in rehabilitation settings that leads to improved patient motor outcomes.enPresentation
