Augmented feedback plays an essential role in stroke rehabilitation therapy. When a force is applied to the arm, an augmented sensory (proprioceptive) cue is provided. The question was to find out if stroke patients can learn reach-and retrieval movements with error-enhanced augmented sensory feedback. The movements were performed over a predefined path, and when deviating of the path a force is provided,...
Patients with moderate to severe hemiparesis following stroke often show abnormal muscle coactivation and a loss of interjoint coordination in the hemiparetic limb. These abnormal stereotypic movement patterns are known in clinical rehabilitation as abnormal secondary torques or synergies. In the beginning of a rehabilitation process the patients often train inside those synergistic patterns, what...
Rehabilitation robotics is a young discipline that will become an imperative when the age of the population rises. The orthopaedic rehabilitation of the elbow joint poses some interesting challenges, discussed in this paper. There is a major difference between neuro-rehabilitation and orthopaedic rehabilitation and thus in the approaches necessary to tackle its challenges. Moreover, the elbow joint...
The design of a wearable upper extremity therapy robot RUPERT IVtrade (Robotic Upper Extremity Repetitive Trainer) device is presented. It is designed to assist in repetitive therapy tasks related to activities of daily living which has been advocated for being more effective for functional recovery. RUPERTtrade has five actuated degrees of freedom driven by compliant and safe pneumatic muscle actuators...
