Pilot Study of Robot-Based Dyadic Training for Chronic Stroke Motor Learning
Overview
This pilot study examines whether robot-based haptic dyads improve motor learning in individuals with chronic stroke. Participants performed a complex tracking task in solo and dyad conditions, with assessments of cognitive, motor, and sensory metrics before training. Results showed that baseline tracking error correlated with cognitive and motor scores; only the solo group demonstrated lower tracking error at assessment after removing an outlier, though neither group showed clear retention. The dyad group exhibited significantly elevated performance, effort, and movement complexity during training. Limitations included task difficulty due to high cognitive demand, small sample size, and stroke heterogeneity.
