DESIGN AND DEVELOPMENT OF ADJUSTABLE RANGE OF MOTION KNEE AND ELBOW BRACES

Abstract

Our project is focused on the design and development of wearable post-operative Knee and Elbow brace with adjustable range of motion for upper and lower limb rehabilitation. In order to in cooperate adjustable range of motion, a unique design was developed that includes two locking pins which makes sure the motion of the limbs stays in between those pins with the increment of 10°. Since the two joints (knee and elbow) are different from each other, the design was slightly modified accordingly. Stress analysis was carried out on locking pins and central pin for both designs on ANSYS. It also has a slider mechanism which makes sure that it can be worn by people of different heights. It also contains an angle sensor which records motion of the patient over the time which could be used by therapists to see the patient’s progress
