Introduction Lower-extremity amputees, the group with which this paper is concerned, include persons who have been subjected to gross anatomic loss of the lower limbs at widely varying levels, such as partial foot amputation, below-knee and above-knee amputations, knee or hip disarticulation, and hemipelvectomy. Amputation at each level is attended by distinctive problems of functional loss, fi...

Abstract—The upper limb amputation exerts a significant burden on the amputee, limiting their ability to perform everyday activities, and degrading quality of life. Amputee patients’ life can be improved if they have natural control over prosthetic hands. Among biological signals, most commonly used predict motor intentions, surface electromyography (sEMG), axial acceleration sensor signals are...

Postural stability of five unilateral above-knee amputee children was measured when wearing the SACH and the experimental Child Amputee Prosthetic Project (CAPP) prosthetic foot. Excursions of the centre of pressure of the supportive forces were recorded via force platform during sustained weight-shifting forward, backward, left, right, and during normal standing. Visual proprioception effects ...

The remarkable performances of amputee athletes in sprint competitions aroused media and scientific interest and led to the question whether running-specific prostheses can be an advantage with respect to able-bodied running. The aim of this study was to bring together motion capture data and Scientific Computing methods to analyze the running motions of an able-bodied and a unilateral transtib...

BACKGROUND Assessment of quality of life can promote health services. The purpose of this study was evaluation of health related quality of life in lower limbs amputee veterans of Iran. METHODS In the present cross sectional study, we compared 38 lower limbs amputee veterans with 50 normal healthy subjects with SF36 questioner in face-to-face interview. RESULTS Amputees had significantly lo...

A software scheme is presented to extract the shapes of tibiae and fibulae from amputee computer tomography (CT) data for use in prosthetic finite element modeling. A snake algorithm is implemented to overcome challenges of bone-soft tissue edge detection common in this application. Means to enhance initial guess contours, ensure contour continuity, overcome point-clustering problems, and handl...

1 Assistant Director, Prosthetics Research Center, Northwestern University, 401 E. Ohio St., Chicago; formerly Research Engineer, Prosthetic Services Centre, Canadian Department of Veterans Affairs, Sunnybrook Hospital, Toronto. Not many people are amputees. Still fewer people are prosthetists. Not many amputees are hip-disarticulation cases. Hence, not many prosthetists are interested in hip-d...

The purpose of this study was to explore the relationship between the forces applied to the starting blocks and the start performances (SPs) of amputee sprinters (ASs) and non-amputee sprinters (NASs). SPs of 154 male and female NASs (100-m personal records [PRs], 9.58-14.00 s) and 7 male ASs (3 unilateral above knee, 3 unilateral below knee, 1 bilateral below knee; 100 m PRs, 11.70-12.70 s) wi...
