Abstract: Stroke is a brain disease, which it causes spasticity and may occurs muscle weakness and also joint stiffness. Besides that, joint stiffness also will occur after joint trauma and with the Continuous passive motion (CPM) exercise, the joint stiffness can be reduces and also maintain the range of motion (ROM) of the joint. Elbow Joint Rehabilitation Device provides Continuous passive motion (CPM) exercises to the patients who have elbow injury or elbow that has undergone surgical procedure and Neurological problems such as stroke and traumatic brain injuries which effected on the elbow. The purpose of this project is to upgrade the existing Elbow Joint Rehabilitation Device to more comfortable to use, more lightly in weight to be handle and carry, and also can operate in DC rechargeable batteries. To develop this project, brushed DC motor is use to move the arm/elbow joint with controllable speed and the degree of movement by using PIC microcontroller (Programmable Interface Controllers). Furthermore, a rechargeable battery is added on the device which to able the device operates in DC power supply. To conduct this project, data collection, testing and data analysis for the stroke and elbow joint injury patients. As a result, we’ll find out the effectiveness of the device to the stroke and elbow injury patient.Abstract: Stroke is a brain disease, which it causes spasticity and may occurs muscle weakness and also joint stiffness.
