Lower Limb Prosthetics - Functional Foot Components

Abstract: The presentation will focus on mechanical testing of prosthetic feet and how testing can be related to clinical practice. Mechanical testing methods, correlations to clinical and biomechanical properties and methodologies for prosthetic foot selection based on verifiable properties will be discussed

Abstract: The effects of a new adaptive prosthetic ankle were investigated in transtibial amputees (TTA) during ambulation on stairs and ramps using instrumented 3D-gait analysis. Significant improvements in kinematics and kinetics were found when walking with the adapted compared to the non-adapted ankle.

Abstract: Quantitative analyses were conducted on 4 male subjects with bilateral transfemoral amputations that walked with and without prosthetic ankle units. Increased ankle motion in the sagittal plane may improve the gait of persons with lower limb amputations while providing a more versatile prosthesis.

Abstract: This study aimed to evaluate various prosthetic feet in ROM & centre of rotation in the sagittal plane. The results suggest that not only are prosthetic foot kinematics different from intact feet, the marker setup has an effect & results may not be generalizable between different prosthetic feet.

Abstract: Persons with transfemoral amputation increased energy consumption while standing on non-level surfaces with current prosthetic foot/ankle devices using a single stiffness value and alignment. Adapting foot/ankle alignment to sagittal plane surface slope significantly reduced oxygen consumption.

Abstract: Thousands of prosthetic feet are used each year in many low-income countries. Following 2006*ISPO recommendations, manufacturing process improve over the years and continued monitoring on foot life span remains crucial. A part of laboratory test,field test play an important role in that prospect.

Abstract: The purpose of this investigation was to determine if increased prosthetic ankle motion improves walking performance of persons with bilateral transtibial amputations. Results indicate that prosthetic ankle components that permit greater motion provide substantial benefit during walking.
