Rehabilitation processes for those who are suffering from low motor skills performance, especially stroke patients is becoming more and more advanced and innovative. Exoskeletons considered one of the best tools used during the stages of rehabilitation process, essentially few weeks after the injury. This research presents a primitive model of a medical exosuit to aid those patients recovering their upper extremities motor skills. Also, it is considered as training tool for their muscles activity. The model is only one degree of freedom. Using a reliable technique, the electromyography (EMG), surface muscle electrodes are being placed on the human upper extremity’s muscles to sense and measure any action in the muscles and record it as electrical signals. After some processing stages for these signals, they command the exosuit’s motors to operate accordingly. Experimental results show that the model is responding smoothly by moving the human forearm at the elbow joint in both directions; flexion and extension. Future investigations will evaluate the model while working in synergy to support the low motor skills performance and stroke patients.
