OBJECTIVE To determine if compensatory actions take place at the pelvis and other joints of the affected lower limb in subjects who were in an early stage of hip osteoarthritis (OA). DESIGN Nonrandomized, case-control study. SETTING A gait laboratory. PARTICIPANTS Seventeen patients with OA of the hip (clinical group) matched with 17 healthy elderly subjects (nonclinical group). INTERVE...

It could be hypothesized that when walking in a linear direction, the most efficient strategy would be to focus the force created by the push-off in the absolute opposite direction to the direction of propulsion. Forces in a medial or lateral direction could then be considered as loss of efficiency since these forces do not create movement in the intended direction. The aim of this study was to...

It has been hypothesised that the stiffness of the plantar aponeurosis after clubfoot surgery affects push-off. Because the first metatarsophalangeal (MTP) joint motion relies on the plantar aponeurosis, it was important to determine whether there was a lack of first MTP joint motion in children with clubfoot that also affected push-off. By examining the motion of the first MTP joint using a mo...

Current commercially available prosthetic feet have succeeded in decreasing the metabolic cost and increasing the speed of walking compared to walking with conventional, mostly solid prosthetic feet. However, there is still a large discrepancy when compared with a non‐disabled gait, and the walking pattern remains strongly disturbed. During the stance phase of the leg, t...

Interactive push VOD system is a new kind of system that incorporates push technology and interactive technique. It can push movies to users at high speeds at off-peak hours for optimal network usage so as to save bandwidth. This paper presents effective software-based solution for processing mass downstream data at terminals of interactive push VOD system, where the service can download movie ...

The slide-board training is a feasible technology to exercise skating during the off-season. While slide-board is much different from ice surface of the actual skating situation, it may distort actual skating posture. The purpose of this study was to analyze the differences in posture during push-off phase between an actual speed skating condition and on slideboard. The result showed that on th...

The rapid growth of web services has already given birth to a set of data dissemination applications. Efficient scheduling techniques are necessary to endow such applications with advanced data processing capability. In this paper we have effectively combined broadcasting of very popular (push) data and dissemination of less popular (pull) data to develop a new hybrid scheduling scheme. The sep...
