Development and evaluation of a functional rehabilitation system for upper extremity function in stroke patients.

The Participants of the training groups participated in individual 3 times per week, for 50 minutes sessions of EMG feedback upper muscle training and others participants participated of EMG-controlled exoskeletal upper limb powered orthosis for exercise training supervise by one physiotherapist with the same background during 2 months. EMG Feedback: The participants realized series of flexion/ extension movements of the elbow, wrist and fingers joints. During the accomplishment of these exercises, the participants seated in front of the computer and will have visual aid of one feedback indicating how much of muscular contraction it must be produced for the accomplishment of each movement. EMG-Controlled Exoskeletal training: During the sessions the particpants realized series of functional upper limbs tasks , such as, to move blocks, boxes and other utensils etc. There is a active-assisted therapy. During active-assisted training, the Exoskeletal provided assistance (by EMG activity trigger) in functional task if the subject was unable to reach it independently.
