Integration of virtual reality based task into controlled dynamometry to enhance motor rehabilitation

The paper presents the development of the virtual reality environment for the joint goniogram controlled dynamometer. The gait goniogram was provided to the dynamometer which performed the requested movement. During the procedure the subject was asked to generate adequate joint torque to control the object in the virtual reality environment. The virtual reality task was prepared in the way that the generated joint torque was comparable with the selected normative and thus prepared for the feasible motor control rehabilitation. The virtual environment was tested in 10 neurologically intact volunteers. The outcomes indicate that the day-to-day increasing speed of task execution had minor impact on the task performance and that the relative rms error of joint torque was considered within the standard deviation of the normative.
