A Study of Human Walking Biomechanics for Ankle-Foot Prosthesis Design

There are a large number of young people who have undergone the same surgery due to work and traffic accidents and terrorist incidents, while the number of elderly individuals who have undergone lower extremity amputation surgery due to vascular problems in our country has increased. The vast majority of these individuals are undergoing under knee amputation surgery. The aim of this study is to examine human walking and its biomechanics, which are the first steps in the design of an ankle prosthesis. In this study, using David A. Winter's clinical gait analysis data, kinematic identification of human gait was conducted. To develop an ankle-foot prosthesis that can perform a 2-Degrees Freedom movement such as Dorsiflexion-Plantarflexion and Inversion-Eversion for people amputated under the knee for various reasons, ankle joint kinematic features that represent a healthy ankle biomechanics should be produced.
