Patients after joint surgery require passive movements that are carried out continuously. The movement is given to the patient to reduce the stiffness that occurs in the joints after joint surgery. Joint stiffness is characterized by pain and limited motion of the joint, which is caused due to reduced synovial fluid. Synovial fluid in the joints can be reduced if the joint is not moved in a long time. This research will design a wrist joint therapy machine that can be moved flexion, extension, ulnar and radial. Besides that, the device to be designed can be adjusted the angle of movement of the tool and the speed of movement of the tool. The angles of movement that can be reached are: (1) flexion movement: 80 ° movement angle, (2) extension movement: 75 ° movement angle, (3) radial movement: 25 ° movement angle, and (4) ulnar movement: movement angle 39 °. Adjustable speeds include: 1 RPM, 2 RPM and 3 RPM. In the result of testing device, we find the maximum difference of movement in 2° and the speed of rotation we have the difference in 0.5 second. Based on experiments that have been done, the tool can be controlled in accordance with the desired movement settings.

Abstract:A controller design for mechatronic system which capable of doing passive therapeutic exercises of patients who have upper extremity limitation is presented in this paper. Expectation from controller is it should produce torque values can exactly repeat degree values depended on time which were taken from first therapy exercises of patients. The designed controller tested with real angle values which was taken from during elbow therapy. Simulation results showed that the proposed control system has good performance at tracking the therapy trajectory. Also that control system may be used for mechatronic upper limb therapy system which can be produced.

PID controller design and comparison between two different gain parameter adjustment method for autonomous physical rehabilitation device is presented in this paper. This device will be capable of doing repeated therapeutic exercises of shoulder joint. That devices main objective is reducing physiotherapist work load. The controllers tested with real angel values. Comparison of simulation results showed Ziegler_Nichols adjustment method has better performance than Matlab's auto-tune method.
