“…3) has been found to be beneficial for monitoring rehabilitation training effectiveness in muscles. (15)(16)(17)(18) A major feature of this mechanism is the ability to mirror movement for training from the nonparetic hand, as expressed through interaction with the grip, to the paretic hand; this is referred to as mirror effect training. (19) This mirror effect has been found to be particularly effective for patients with advanced paralysis.…”

The authors have developed a practical wrist rehabilitation robot for hemiplegic patients. It consists of a desk equipped with mechanical rotating handle grips, sensors, a computer, and a display. Myoelectric sensors, which are bioelectric signal detectors, are used to monitor the extensor carpi radialis longus/brevis muscle and flexor carpi radialis muscle activity during training. Training effectiveness is ensured by monitoring the extension and flexion of the appropriate muscles. A feature of the system is that it operates as a dual-wrist system, developed to mirror the training between wrists, making autonomous training of either wrist possible. A user-friendly touch screen interface is provided; the screen displays progress data and images to encourage the patients towards completion of the necessary rehabilitation tasks critical to facilitate recovery. The developed robotic system is relatively compact and portable. The effectiveness of this system has been confirmed through clinical trials, and motivational effectiveness has been confirmed through electroencephalography (EEG)-based evaluation and direct survey.

Wrist rehabilitation is needed to help post-stroke and post-surgery patients recover from wrist fracture or injury. Traditional rehabilitation training is conducted by a therapist in a hospital, which hinders timely treatment due to the corresponding time and space constraints. This paper presents the design and implementation of a soft parallel robot for automated wrist rehabilitation. The presented wrist rehabilitation robot integrates the advantages of both soft robot and parallel robot structures. Unlike traditional rigid-body based rehabilitation robots, this soft parallel robot exhibits a compact structure, which is highly secure, adaptable, and flexible and thus a low-cost solution for personalized treatment. The proposed soft wrist-rehabilitation robot is driven by six evenly distributed linear actuators using pneumatic artificial muscles and one central linear electric motor. The introduced parallel-kinematic mechanism design enables the enhancement of the output stiffness of the soft robot for practical use. An electromyography sensor is adopted to provide feedback signals for evaluating the rehabilitation training process. A kinematic model of the designed robot is derived, and a prototype is fabricated for experimental testing. The results demonstrate that the developed soft rehabilitation robot can assist the wrist to realize all the required training motions, including abduction-adduction, flexion-extension, and supination-pronation. The compact and lightweight structure of this novel robot makes it convenient to use, and suitable rehabilitation training modes can be chosen for tailored rehabilitation at home or in a hospital.
