Abstract: The authors have developed a practical wrist
rehabilitation robot for hemiplegic patients. It consists of a mechanical
rotation unit, sensor, grip, and computer system. A myoelectric sensor is
used to monitor the extensor carpi radialis longus/brevis muscle and flexor
carpi radialis muscle activity during training. The training robot can
provoke training through myoelectric sensors, a biological signal detector
and processor in advance, so that patients can undergo effective training
of extention and flexion in an excited condition. In addition, both-wrist
system has been developed for mirror effect training, which is the most
effective function of the system, so that autonomous training using both
wrists is possible. Furthermore, a user-friendly screen interface with
easily recognizable touch panels has been developed to give effective
training for patients. The developed robot is small size and easy to carry.
The developed aspiring interface system is effective to motivate the
training of patients. The effectiveness of the robot system has been
verified in hospital trails.
Keywords: Wrist rehabilitation robot, myoelectric sensor, mirror effect, interface system
