Construction of Tele-Rehabilitation Platform Using Distributed Common Object Models

Rehabilitation plays an important role in the future aging society. However, due to increasing aging population, the large amount of therapy efforts and spaces for rehabilitation may be not sufficient. Therefore, the tele-rehabilitation approach is proposed to resolve the shortages of physical therapists and rehabilitation spaces. The tele-rehabilitation is a technology that monitors and controls the rehabilitation equipments in efficient and convenient manners through the network to achieve remote rehabilitations. To achieve efficient and safe tele-rehabilitations, a real-time rehabilitation platform for database accessing, message exchange, signal and status monitoring, and remote manipulations of rehabilitation equipments are desired in this paper based on distributed object-oriented techniques. The proposed distributed object-oriented tele-rehabilitation platform also achieves the purposes of robustness and loading balance issues. In addition, a service allocation algorithm is proposed to dynamically balance the overall loading of each host server so that the service quality of the platform can be improved. The performance of the CPU and utilization of the dynamic memory of the host servers are all measured and recorded periodically as the bases of allocating new services and re justifying executing services in real-time. Finally, the fault detection and recovery algorithm is proposed to construct robust tele-rehabilitation platform. Therefore, the proposed tele-rehabilitation platform achieves time-efficient and cost-effective purposes.
