Identifying classifier input signals to predict a cross-slope during transtibial amputee walking
Advanced prosthetic foot designs often incorporate mechanisms that adapt to terrain changes in real-time to improve mobility. Early identification of terrain (e.g., cross-slopes) is critical to appropriate adaptation. This study suggests that a simple classifier based on linear discriminant analysis can accurately predict a cross-slope encountered (0°, -15°, 15°) using measurements from the res...
متن کاملKinematics of Hip, Knee and Ankle During Cross- Slope Walking
Purpose: Little information is available on joint kinematic adaptations during walking on cross-slope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking. Methods: This is a quasi-experimental study...
متن کاملThe effects of prosthetic foot stiffness on transtibial amputee walking mechanics and balance control during turning.
BACKGROUND Little evidence exists regarding how prosthesis design characteristics affect performance in tasks that challenge mediolateral balance such as turning. This study assesses the influence of prosthetic foot stiffness on amputee walking mechanics and balance control during a continuous turning task. METHODS Three-dimensional kinematic and kinetic data were collected from eight unilate...
متن کاملTranstibial amputee joint rotation moments during straight-line walking and a common turning task with and without a torsion adapter.
Amputees lack movement and control mechanisms at the foot and ankle that result in different strategies for locomotion than nonamputees. The torsion adapter is a prosthetic device designed to minimize shear stress at the residual limb by facilitating rotation in the transverse plane. This study determined if the addition of a torsion adapter alters lower-limb joint rotation moments of transtibi...
متن کاملMechanical energetic contributions from individual muscles and elastic prosthetic feet during symmetric unilateral transtibial amputee walking: a theoretical study.
Energy storage and return (ESAR) foot-ankle prostheses have been developed in an effort to improve gait performance in lower-limb amputees. However, little is known about their effectiveness in providing the body segment mechanical energetics normally provided by the ankle muscles. The objective of this theoretical study was to use muscle-actuated forward dynamics simulations of unilateral tran...
