BFeedback distortion to increase strength and mobility

Abstract Amethod,for using visual distortion to overcome Learned Nonuse in stroke victims is described, and results from a preliminary ,experiment ,on unimpaired ,subjects are presented. A visual display was used to present increasingly distorted feedback ,about the force exerted by a ,subject. Visual distortion encouraged ,unimpaired ,subjects ,to increase their force production ,by more ,than 30%. In addition, the effects of different amounts of distortion on force production were analyzed; visual feedback distortions ofup,to 28.8% linearly increased the force exerted by subjects.
