| ABSTRACT |
he potentiometer electrogoniometer has been developed to investigate the elbow joint motion. The device will detect the flexion and extension movement of the arm which more specifically the angles of movement occur at the elbow.the device work as a hinge joint that is similar to the join of an elbow. the data from the rotary motion are been calclated through a microcontroller and finally shown in real time using a liquid crystal display (LCD) on degree (0). the prototype of the device is developed with range of motion from 0o until 230o.
