Abstract

One most common treatment for muscular diseases is the physical therapy. To prevent muscle atrophy and paralysis an injured person must continue to exercise the body even if lacks muscle force and conditions. When dealing with these cases, the trained professional must move the patients through a series of motion exercises to spur the regeneration. This, however can exhaust the clinician impairing the exercise. A solution around this problem is the use of intelligent orthosis that, with the help of mechanical actuators will move the selected body limbs through a series of motions, and with the use of sensors will achieve repeatability and precision. This study presents a mechanical and electronic design for the construction an intelligent orthosis for the upper limbs. The project aimed in designing an orthotic device with light weight, in which the motion of the limbs is triggered by Bowden cables connected in one end to the limbs and the other to a stepper motor located at a backpack carried by the patient. This design also comprises a selection of sensors that will provide the necessary information to move the body with a precision of path, and also to quantify the muscle forces facilitating the physical condition evaluation through time. The necessary simulations we made to certify the design mechanical strength and kinematic functionality.
