Determining asymmetry of roll-over shapes in prosthetic walking.
How does the inherent asymmetry of the locomotor system in people with lower-limb amputation affect the ankle-foot roll-over shape of prosthetic walking? In a single-case design, we evaluated the walking patterns of six people with lower-limb amputation (3 transtibial and 3 transfemoral) and three matched nondisabled controls. We analyzed the walking patterns in terms of roll-over characteristi...
متن کاملComparative roll-over analysis of prosthetic feet.
A prosthetic foot is a key element of a prosthetic leg, literally forming the basis for a stable and efficient amputee gait. We determined the roll-over characteristics of a broad range of prosthetic feet and examined the effect of a variety of shoes on these characteristics. The body weight of a person acting on a prosthetic foot during roll-over was emulated by means of an inverted pendulum-l...
متن کاملEffect of prosthetic ankle units on roll-over shape characteristics during walking in persons with bilateral transtibial amputations.
Some important walking functions are adversely affected or eliminated in prosthesis users because of reduced or absent ankle motion. This retrospective data analysis determined the effect of prosthetic ankle units on the characteristics of the ankle-foot roll-over shape in persons with bilateral transtibial amputations. Seventeen subjects were fitted with Endolite Multiflex Ankles to provide an...
متن کاملJRRD at a Glance Effect of prosthetic ankle units on roll-over shape characteristics during walking in persons with bilateral transtibial amputations
Some functions of walking are adversely affected in prosthesis users because of reduced or absent ankle motion. However, combining a prosthetic ankle unit with a particular prosthetic foot could have unanticipated consequences. This study investigated the effect of prosthetic ankle units on the gait of persons with bilateral transtibial amputations. Subjects were tested while walking with and w...
متن کاملEffects of adding weight to the torso on roll-over characteristics of walking.
Ten participants without physical impairment walked with 0 kg, 11.5 kg, and 23.0 kg of added weight equally distributed about the torso in a harness. At each weight level, the participants walked at slow, normal, and fast self-selected walking speeds. We examined the roll-over characteristics by determining the ankle-foot and knee-ankle-foot roll-over shapes. These shapes, which are the effecti...
