Bionic ankle-foot prosthesis normalizes walking gait for persons with leg amputation.
Over time, leg prostheses have improved in design, but have been incapable of actively adapting to different walking velocities in a manner comparable to a biological limb. People with a leg amputation using such commercially available passive-elastic prostheses require significantly more metabolic energy to walk at the same velocities, prefer to walk slower and have abnormal biomechanics compa...
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 کاملToe clearance when walking in people with unilateral transtibial amputation: effects of passive hydraulic ankle.
Most clinically available prosthetic feet have a rigid attachment or incorporate an "ankle" device allowing elastic articulation during stance, with the foot returning to a "neutral" position at toe-off. We investigated whether using a foot with a hydraulically controlled articulating ankle that allows the foot to be relatively dorsiflexed at toe-off and throughout swing would increase minimum ...
متن کاملA preliminary investigation of pelvic obliquity patterns during gait in persons with transtibial and transfemoral amputation.
Differences in pelvic obliquity between small groups of persons with unilateral lower limb amputation and subjects without amputation were analyzed. Kinematic walking data were collected as six males with transtibial amputation and three males with transfemoral amputation walked over a range of speeds. The pelvic obliquity patterns and amplitudes from the groups with amputation were compared to...
متن کاملLocomotor adaptability in persons with unilateral transtibial amputation
BACKGROUND Locomotor adaptation enables walkers to modify strategies when faced with challenging walking conditions. While a variety of neurological injuries can impair locomotor adaptability, the effect of a lower extremity amputation on adaptability is poorly understood. OBJECTIVE Determine if locomotor adaptability is impaired in persons with unilateral transtibial amputation (TTA). METH...
