Elizabeth Russell Esposito, Christopher A Rábago, Jason Wilken
BACKGROUND: Recent literature indicates equivalent costs of walking can be achieved after a transtibial amputation when the individual is young, active, and/or has extensive access to rehabilitative care. It is unknown if a similar cohort with transfemoral amputation can also achieve lower metabolic costs of walking than previously reported. OBJECTIVE: Compare metabolic cost in individuals with a transfemoral amputation to controls and to the literature across a range of walking speeds...

Helen Lindner, Ayako Hiyoshi, Liselotte Hermansson
BACKGROUND: The International Classification of functioning, disability and health refers capacity to what an individual can do in a standardised environment and describes performance as what an individual really does and whether the individual encounters any difficulty in the real-life environment. Measures of capacity and performance can help to determine if there is any gap between them that may restrict participation. The aim of this study was to explore the relationship between capacity scores obtained in a standardised clinical setting and proportional ease of performance obtained from a real-life environment...

BACKGROUND: To improve gait function in children with cerebral palsy, ankle-foot orthoses are often prescribed. However, until now, little attention has been devoted to the effect of ankle-foot orthoses on the postural control during walking in children with cerebral palsy. OBJECTIVES: The aim was to compare the differences in thorax, spine, and pelvis movements in children with cerebral palsy during walking barefoot and walking with ankle-foot orthoses. STUDY DESIGN: Clinical study with an intra subject design...

BACKGROUND: Prosthetic feet are prescribed based on their mechanical function and user functional level. Subtle changes to the stiffness and hysteresis of heel, midfoot, and forefoot regions can influence the dynamics and economy of gait in prosthesis users. However, the user's choice of shoes may alter the prosthetic foot-shoe system mechanical characteristics, compromising carefully prescribed and rigorously engineered performance of feet. OBJECTIVES: Observe the effects of footwear on the mechanical properties of the prosthetic foot-shoe system including commonly prescribed prosthetic feet...

Riemke Ga de Boer, Marieke A Paping, Bert Kap, Jan Hb Geertzen
BACKGROUND: In all, 68% of all lower limb amputees experience residual limb pain. More than 95% of all lower limb amputations in developed countries are due to peripheral artery occlusive disease in combination with diabetes mellitus. Therefore, claudication, which is one of the most common manifestations of peripheral artery occlusive disease, should be taken into consideration in making a differential diagnosis of residual limb pain. Case description and methods: We present a case study of a 60-year-old diabetic patient who underwent a transfemoral amputation due to peripheral artery occlusive disease and who experiences residual limb pain...
