We suggest that it may be of clinical interest to evaluate to which extent this kind of motor learning capability is impaired in children affected by cerebal palsy. Methods We adapted the protocol already used with adults which employs a velocity dependant viscous field and compared the performance of a group of subjects affected by Cerebral Palsy CP group 7 subjects with a Control group of unimpaired age-matched children. The protocol included a familiarization phase FA during which no force was applied a force field adaptation phase CF and a wash-out phase WO in which the field was removed. During the CF phase the field was shut down in a number of randomly selected catch trials which were used in order to evaluate the learning index for each single subject and the two groups. Lateral deviation speed and acceleration peaks and average speed were evaluated for each trajectory a directional analysis was performed in order to inspect the role of the limb s inertial anisotropy in the different experimental phases.
