The most outstanding feature of 'Biomechanics of Lower Limb Prosthetics' is the demonstration of the practicality of biomechanics, when applied to lower limb prosthetics. Several original concepts are described, one of which, 'rolling technology,' has been implemented in prosthetic devices, while the principle of 'reciprocal anti-resonance in locomotion' addresses future studies. A concept of anthropomorphicity presented by the author is a key tool in planning the design of an artificial limb or its components.Measurement procedures and equipment used in biomechanical laboratories are presented. The book demonstrates how the analysis of biomechanical data is a tool in the decision-making process of a prosthetic designer and clinician. The author shares his experience in the development of a protocol for biomechanics subject trials used in NIH-supported studies.
