Disease and physical disability may serve as strong incentives for the attainment of motor performances, some of them of a high order of complexity, and of athletic excellence. In one case motivation, possibly from conflict, produced achievements revealing a new insight into the scope of compensatory adjustment of the nervous system. The second case indicates the extent to which an established neuromotor pattern can be projected into previously untrained skeletomuscular regions. Both cases illustrate the possibility of complete functional rehabilitation after major disablement.
