Can partial foot prostheses effectively restore foot length?
Our understanding of how partial foot prostheses function stems from static force analyses, where assumptions about the location of the ground reaction force during terminal stance have been made. While such assumptions seemed reasonably based on an understanding of normal gait, they are often illogical based on what is observed clinically. As such, the aim of this work was to evaluate the beli...
متن کاملPartial Foot Prostheses/Orthoses
Prostheses and orthoses prescribed for partial foot amputations vary in design and principle. Authors have described the need or the lack of need of toe lever arms, extensions above or below the ankle, and hard and soft sockets. Al most every design violates a principle thought to be a requirement of the other designers of partial foot prostheses/orthoses. The purpose of this paper is to descr...
متن کاملEquipment and methods for laboratory testing of ankle-foot prostheses as exemplified by the Jaipur foot.
A load deflection and a cyclic loading apparatus capable of measuring dorsiflexion/plantarflexion, pronation/supination, internal/external rotation, and cyclic dorsiflexion (60 cycles per minute) of ankle-foot prostheses are described. A test protocol was developed to assess the functional parameters of the Jaipur ankle-foot prosthesis before and after prolonged cyclic loading, with the simulta...
متن کاملEffect of prosthetic design on center of pressure excursion in partial foot prostheses.
Investigations into the gait of persons with partial foot amputation (PFA) suggest that the effective foot length can be restored when the prosthesis incorporates a relatively stiff forefoot, restricts dorsiflexion, and includes a mechanism whereby forces caused by loading the toe lever can be comfortably distributed to the leg (e.g., an anterior tibial shell). The purpose of this investigation...
متن کاملHeight estimation from foot and shoeprint length.
Foot length displays a biological correlation with height that suggests the latter might be estimated from foot- or shoeprints when such evidence provides an investigator the best or only opportunity to gauge that aspect of a suspect's physical description. Previous utilization of percentages and linear regressions of foot length to make height estimates is reviewed and appraised, as is such us...
