Effect of game speed and surface perturbations on postural control in a virtual environment.

The aim of this study was to describe the relationship between performance and difficulty set by altering game velocity and surface perturbations in a virtual game environment. Performance deteriorates as game difficulty increases when changing game velocity and surface perturbations. Adjustment of both game velocity and the introduction of surface perturbations independently appear to be simple and effective methods of customising task difficulty as a function of patients’ motor ability during rehabilitation
