Patients who experience paralysis in their extremity such as post-stroke patients and post-joint surgery require regular rehabilitation to restore their mobility. Rehabilitation is usually done in a hospital or a rehabilitation center with the help of a doctor or therapist. However, this is a problem for patients who have limited resources. In one of the researches of the Biomechanics Laboratory of Bandung Institute of Technology, a prototype of a home-based lower extremity rehabilitation device with muscle recovery feature was developed. In this study, improvements were made to the mechanism to overcome the problems contained in the previous prototype. The research begins by evaluating the previous prototype design and determining the design requirements & objectives. Based on the evaluation, product development focused on conciseness, lightness, and the accuracy of the angle of motion of the linkages and legs. The product in this study was then compared with the previous prototype to see an increase in performance and dimensions. The mechanism used is six rods, different from the previous four rods. Based on the results of the prototype, the prototype is lighter than the previous prototype, from 22.3 kg to 13.5 kg. The length dimension of the prototype is 1058 mm, which is more compact than the previous prototype, which is 1346 mm. The resulting angle of motion on the legs is more in line with the angle of motion of the trunk than in the previous prototype.
