Influencia de la asimetría de la marcha en el comportamiento biomecánico de las articulaciones de cadera en pacientes con prótesis transfemorales Influence of gait asymmetry on hip joints biomechanical behavior in patients with transfemoral prostheses

This study establishes the existing relation between gait asymmetry of an amputee that wears passive transfemoral prosthesis and the appearance of the hip pathologies in healthy and amputated limbs. This purpose is achieved through an integrated assessment of the results obtained out of kinematic and dynamic analysis of the amputee gait throughout the videographic techniques and the use of clinical trials such as radiography and densitometry, as the most important aspect related to design assessment and functionality of the transfemoral prosthesis. The result of the spatiotemporal variables measurement performed on healthy and amputee patients established a significant difference between gait patterns of healthy and amputee patients, and between healthy and amputated limbs of the amputee. Dynamic inverse analysis (DIA) and implementation of finite element method demonstrated that patients with such gait asymmetry have dynamic imbalance related to the degenerative hip diseases. Performed clinical trials showed the prevalence of osteoporosis
