Brief Summary

There is a lack of effective rehabilitation methods for visio-spatial neglect (VSN). By using virtual technology, a new method (virtual reality, VR method) has been created which focuses on stimulating attention networks: top down scanning training in a 3D game, combined with intense visual, audio and tactile bottom-up stimulation, also including visuo-motor training. Objective. To evaluate clinical and functional improvement in stroke patients with VSN, as well as before and after training with the new VR method Method:- An intense visio spatial scanning training, enhanced by directed visual, audio and tactile stimulation cues and feedback, also including visio-motor activation was designed in a VR game. The in-house developed software was based on the Tetris game. The VR method consists of an interactive 3D environment: a desktop computer, a monitor, 3D glasses and a force feedback interface. 15 patients with chronic (\>6 months) visio spatial neglect was included due to right-sided ischemia. A VR neglect test battery including a Posner task were repeated three times during a 5 weeks baseline before the training started (to establish the chronic state) and again after 15 hours training (3x1 h for 5 weeks). Evaluation of a new method for training attention after stroke causing visio spatial neglect. The method has been designed for home rehabilitation and is well suited for a tele-medicine approach. It was built with standard components and is easy to manufacture at a low cost. The idea is to give access to effective training, to make it available at the stroke unit with the possibility for the patient to loan it it at discharge for home rehabilitation. The concept of an all in one, easy-to-use device for testing, training and outcome evaluation should be beneficial These preliminare results has been promising and indicates that the RehAtt™ method could become an further developed into an effective and stimulating intervention tool that would lower rehabilitation costs and reduce tiresome travelling to hospitals for training.
