Full or partial loss of function in the lower limb is an increasingly common ailment associated with a wide range of injuries, disease processes, and other conditions including sports, occupational, spinal cord injuries, and strokes. Some people are even born with disabilities. To treat such abnormalities, large number of physiotherapy exercises is used which are labour intensive requiring high levels of one to one attention from highly skilled medical personnel. Prior to the introduc-tion of machine assistance, physical therapists have had to manually move the patient’s limbs. This leads to two problems, repetition and strain. The physical therapist is not able to precisely duplicate the movements each time. The machines are capable of doing so, leading to a superior rehabilitation for the patient. The therapists experience strain from having to move the patient’s limbs. To solve the above problems, a device has been developed that helps the disabled ones to perform flexion and extension of lower limbs. It is a framework made up of aluminum, with knee joints and an actuator attached to it, which has to be worn. The complete setup weighs not more than 2 kg. The aim of the project is to generate walking mechanism using PSOC microcontroller.
