DESIGN & MANUFACTURING OF ORTHOPEDIC ANKLE RECOVERY SYSTEM

Abstract

Ankle is one of the most important joints in a human body, which helps balancing the human body during ambulation. Also ankles are the most common site of sprain injuries. There are two methods to rehabilitate patient with such injuries. One is active assisted and the other is passive assisted. This project is concerned with orthopaedic rehabilitation of a patient with ankle injury using active assisted range of motion. In active assisted range of motion, the doctor or therapist manually helps the patient in moving a particular body part along a joint. The patient exerts a small amount of effort during this movement. The project discusses design of an active assisted ankle recovery system. This system will be able to perform dorsal and plantar inflexion, inversion, and eversion. Our design is based on a rotating platform having one end fixed to another stationary platform with two actuators. The other end of this top platform is connected to car window power motors via two strings attached to its lower part. The motors are welded to the lower platform. With the use of electronic components like Arduino, relay module and power supply, the motors can be rotated and this enables the platform to rotate.
