Motor learning and compensatory movement are important aspects of prosthesis training yet relatively little quantitative evidence supports our current understanding how motor control compensation develop in the novel body-powered user. The goal this study is to assess these through functional, kinematic, kinetic analyses using a within-subject paradigm compared across two time points. joints evaluated include left right shoulders, torso, elbow. Six abled-bodied subjects (age 27 ± 3) bypass completed Jebsen-Taylor Hand Function Test targeted Box Blocks after five sessions again ten sessions. Significant differences parameters included reduced times complete tasks, normalized jerk for most more variable changes efficiency individual tasks measured as range motion, maximum angle, average moment. Normalized jerk, joint specific path length, moment presented first unique context device type. These findings quantitatively describe numerous able-bodied that may be useful guiding future rehabilitation users.
