An externally actuated glove, controlled by a microprocessor, is being developed to assist finger extension in stroke survivors. The goal of this device is to allow repeated practice of specific tasks for hand therapy in a home environment. The user can control the device by three different means: voice recognition, electromyography, or manual control. These inputs can be used either independently...
The hand motion function of Cerebral Palsy (CP) and stroke patients could be improved by task-oriented rehabilitation. Nowadays, there is a move in the development of the rehabilitation environment from the real world to virtual worlds. Patients could benefit from virtual reality (VR) based rehabilitation by multimodal and multiform feedback. However, it is recognised that such feedback might cause...
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...
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...
In this study, a myoelectrically controlled robotic system with one degree of freedom was developed to assist elbow training in the horizontal plane for patients after stroke. The system could provide assistive extension torque which was proportional to the amplitude of the subject's processed and normalized electromyograhpic (EMG) signal from triceps. The system also provided different resistive...

Spasticity in stroke patients interferes with coordinated muscle firing patterns of the lower extremity leading to gait abnormalities. The goal of this study was to improve ankle function during walking by augmenting treadmill gait retraining with a visual EMG biofeedback technique. Eight stroke patients who could ambulate between 0.5 and 0.9 m/s participated in the study. The training consisted of...
