A Review Study on Measurement and Evaluation of Prosthesis Testing Platform during Gait Cycle within Sagittal Plane

The main problem with designing prostheses is the ability to assess newly manufactured devices on patients under unsafe conditions. Some of the issues that obstruct the testing process of the prosthetic limbs on amputees are informed consent, safety straps, and inadequate repetitiveness. This paper introduced a literature study regarding prosthesis testing platforms in which the sagittal plane is considered in all motions and forces. The article focused on the mechanical design, the actuator system, and the control strategies of test platforms to assess the functional characteristics of a prosthetic lower limb, such as the types of movements and loads, the technologies adopted, and the types of control techniques that have been used to design closed-loop motion. Furthermore, this study illustrated the performance test of a prosthetic limb through kinematic and kinetic measurement. In conclusion, these problems can be solved by utilizing robotic testing, which provides extra benefits that can be activated for a long time and working in environments that are dangerous for patients.
