We developed an interface to the commercial video game Guitar Heroreg III using surface electromyography (EMG) to create a novel training and evaluation device for upperextremity amputees. Rather than pressing the keys with onepsilas fingers as in the normal game, in our modified version a user merely flexes his or her index, middle, or ring finger muscles, and the resulting myoelectric activity is...
Antiphasic electromyographic (EMG) activities between biarticular arm muscles are indispensable for smooth performance. In the case of two-joint arm movement in a planar horizontal plane, elbow and shoulder joint movements were achieved by the biceps brachii (BB) and the triceps brachii muscles (TB). To our knowledge, however, no conclusions have been reached concerning the antiphasic EMG activities...
The motor recovery procedure during robot-assisted wrist rehabilitation for persons after stroke has not been well studied previously. In this work, we carried out a comparative study on the training effects on 10 hemiplegic persons with chronic stroke between a wrist treatment assisted by an electromyography (EMG)-driven robotic system (interactive treatment, n=5, EMG group) and a wrist treatment...
For central nervous system (CNS) impaired patients, e.g. after stroke, the achievement of an independent, stable gait function and endurance in walking is essential for independent mobility in daily life. Modern concepts of rehabilitation favor a task specific repetitive training, that facilitates natural motion and muscle activation patterns, i.e. in addition to commonly practiced floor walking other...
Robot and functional electrical stimulation (FES) techniques have been used for improving motor functions after stroke respectively. In this work, we aimed to examine the combined effects from Robot and FES in post-stroke wrist rehabilitation. We developed a new electromyography (EMG)-driven FES-robot system with a control algorithm, which was interactive to the voluntary motor inputs from persons...
This paper suggest a prototype of a 3 degree of freedom myoelectric hand system for the upper limb amputee. It is consists of the 3 main part, the myoelectric sensor, the myoelectric hand, and training system: the first is a surface electrode myoelectric sensor to extract the raw electromyogram signal from the residual muscle of the upper limb amputee. To implement 6 essential function of the hand,...
The development of a training system in the field of rehabilitation has always been a challenge for scientists. Surface electromyographical signals are widely used as input signals for upper limb prosthetic devices. The great mental effort of patients fitted with myoelectric prostheses during the training stage, can be reduced by using a simulator of such device. This paper presents an architecture...
