The goal of this project is to build a virtual reality therapy system for patients recovering motor function after stroke. Stroke is one of the most common conditions requiring rehabilitation, and it is a major source of disability with a large personal and societal burden. Conventional physical therapies are resource-intensive, involve intensive, repetitive training and are limited to addressing nervous system recovery via manipulation of the periphery. Computer-based rehabilitation approaches can mobilize additional cognitive and motivational systems that may speed up recovery by delivering intensive, concentrated therapy in a personalized exercise environment where the intensity of practice and positive feedback can be consistently and systematically manipulated and enhanced to create the most appropriate learning approach. Furthermore, computer-based rehabilitation can reduce therapy costs, improve patient/staff motivation, allow objective evaluation of patient status and offer the possibility for home-based rehabilitation and monitoring.
Quelles sont les particularités de ce projet?
Gebert Rüf Stiftung supports this innovative project which has clear potential for more effective stroke rehabilitation with large social and economic benefits.
Several prototypes of the system have been constructed, focusing on rehabilitation of upper arm movements. Novel patient-optimized data gloves and entertaining gaming scenarios have been developed. Five systems are now in active use in several rehabilitation clinics with acute stroke patients, chronic stroke patients and paediatric patients with various neurological disorders. Preliminary user acceptance testing shows high user motivation to use the system, high acceptance of the therapy protocol and indications of beneficial effects for arm and hand function. More extensive patient testing is in progress. The technologies behind the system are now being commercialized.
