Hybrid CPM/CAM Physiotherapy by Use of the Slide-Mode Fuzzy Neural Network Control

Continuous passive motion (CPM) and controllable active motion (CAM) physiotherapy devices are commonly used to promote rehabilitation of damaged joints. A device involving the use of a CPM and CAM combination but without the CAM-type resistance components is presented. While in the CPM mode, the electric motor functions traditionally, but in the CAM mode, the motor exerts an opposing force against the patient´s activity, creating the effect of a spring performance. Such motor force is stimulated by the slidingmode adaptive fuzzy neural network controller. For convenient use, the system connects to the Internet or the training data can be accessed by automatic monitoring of research stations, home patients or telemedicine applications.
