摘要: 英文摘要PDF

Virtua l reality (VR) environments present nowadays a powerful tool for visual feedback in assessment and traini ng programs of rehab ilitation . Designing appropriate targe t-oriented tasks may enhance the rehabilitation options available in biomechanical dynamo metry. The subjects are motivated to achieve a goal in the VR environment, and there fore, their perfor mance often increases. This adds a significant value to the evaluation of the subject's capabi lities and design of the appro priate train ing program that may enhance the selective joi nt torque contro l in children with cere bral palsy. In this paper, we suggest a VR environment that offers motivation for maxima l joint torque generation and VE for joint torque control training. A dynamometer with torque sensor and axis motor was used in the process and enab led biomechanical information, i.e. knee joint torque and surface electromyography, assessment during the targe t-oriented VR based task. A 12-year old child with cerebral palsy participated in the case study. The protocol consisted of three consecu tive days of virtual reality-support ed training under various conditions, like task velocity and difficulty level. Our data suggested that there were improvements in the knee joint torque tracking and increased target hit score regardless of the task difficulty level. Besides the improvement of the knee joint torque control, presumably more muscle power cou ld be generated, resulting in more successful performance at targets where high joint torque was required. Apparently high level of motivation has been noticed. The advantages of using VE for rehabilitation services were shown in variability of attractive target oriented tasks, repeatability and highly motivated subjects . Hereby, a VR environment guided dynamometer based assessment and train ing for single joint was demonstrated. The promising outcomes call for longer training period and clinical evaluation of modem therapeutic approach.
