Abstract Background Mechanical guidance with a robotic device is a candidate technique for teaching people desired movement patterns during motor rehabilitation surgery and sports training but it is unclear how effective this approach is as compared to visual demonstration alone. Further little is known about motor learning and retention involved with either robot-mediated mechanical guidance or visual demonstration alone. Methods Healthy subjects n 20 attempted to reproduce a novel three-dimensional path after practicing it with mechanical guidance from a robot. Subjects viewed their arm as the robot guided it so this haptic guidance training condition provided both somatosensory and visual input. Learning was compared to reproducing the movement following only visual observation of the robot moving along
