... envi- ronment. Bach-y-Rita et al [31] and Reinkensmeyer [32] used games and simple or commercial hardware to assess and motivate arm use. Our approach also uses commercially available, game- based activities ... only for day 2. Again as in EP1, the EMG and video data are not analyzed here and only rep- resentative tracking data are analyzed in the results sec- tion. Representative tracking ta...

... the dynamics of motor adaptation during rehabilitation must be defined. A key question is whether motor rehabilitation is indeed akin to learning a new sensory motor transformation, as we assumed ... defined a motor learning task that was amenable to computational analysis – unim- paired subjects had to overcome a virtual impairment applied to their leg with a rob...
