There is an urgent need in the rehabilitation of above knee amputees (AKA) for inexpensive systems able to provide, in real-time, quantitative information about gait symmetry. Traditional optoelectronic systems fail in this task being restricted to the laboratory workspace, expensive and time consuming. As a solution, we developed a protocol based on wearable mono-axial gyroscopes named Symmetry Evaluation of Amputee Gait (SEAG). SEAG requires the acquisition of the medio-lateral angular velocity of both shanks (ωML) with gyroscopes, and identifies specific features of these signals related to heel-strike (HS) and toe-off (TO) of both sides. Aim of this study is to validate the reliability of SEAG in steps detection, when applied to AKA with different ages and training.

Abstract
There is an urgent need in the rehabilitation of above knee amputees (AKA) for inexpensive systems able to provide, in real-time, quantitative information about gait symmetry. Traditional optoelectronic systems fail in this task being restricted to the laboratory workspace, expensive and time consuming. As a solution, we developed a protocol based on wearable mono-axial gyroscopes named Symmetry Evaluation of Amputee Gait (SEAG). SEAG requires the acquisition of the medio-lateral angular velocity of both shanks (ωML) with gyroscopes, and identifies specific features of these signals related to heel-strike (HS) and toe-off (TO) of both sides. Aim of this study is to validate the reliability of SEAG in steps detection, when applied to AKA with different ages and training.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
