Lower Limb Prostheses

The paper investigates the feasibility of externally powered lower-limb prostheses, in particular those in which walking motions would be automatically controlled. The lack of a suitable power supply is a major obstacle to the rapid development of a practical prosthesis, but a theoretical and practical study is being made of a ‘prototype walking device’, out of which, if successful, a prosthesis might evolve. The configuration of this device is outlined, with reasons for the choice, and possible actuators and sensors are discussed. A mathematical model is formulated and a control scheme is outlined which should enable the device to walk stably on small feet over uneven terrain. Results of analogue simulation of the device are summarized.

Lower Limb Prostheses

The human foot consists of complex sets of joints. The adaptive nature of the human foot enables it to be stable on any uneven surface. It is important to have such adaptive capabilities in the artificial prosthesis to achieve most of the essential movements for lower-limb amputees. However, many existing lower-limb prostheses lack the adaptive nature. This paper reviews lower-limb adaptive foot prostheses. In order to understand the design concepts of adaptive foot prostheses, the biomechanics of human foot have been explained. Additionally, the requirements and design challenges are investigated and presented. In this review, adaptive foot prostheses are classified according to actuation method. Furthermore, merits and demerits of present-day adaptive foot prostheses are presented based on the hardware construction. The hardware configurations of recent adaptive foot prostheses are analyzed and compared. At the end, potential future developments are highlighted.
