This paper presents the results of a project to evaluate different methods of gait cycle selection on the analysis of electromyography recorded during gait. Electromyography (EMG) describes the electrical activity associated with the muscle and is often interpreted in gait analysis using a simultaneously obtained signal to identify phases of the gait cycle. Phase transitions are often selected ...

INTRODUCTION People have been interested in movement analysis in general, and gait analysis in particular, since ancient times. Aristotle, Hippocrates, Galen, Leonardo da Vinci and Honoré de Balzac all used observation to analyse the gait of human beings. The purpose of this study is to compare Honoré de Balzac's writings with a scientific analysis of human gait. SOURCES Honoré de Balzac's Th...

BACKGROUND AND PURPOSE Functional electrical stimulation (FES) is a popular poststroke gait rehabilitation intervention. Although stroke causes multijoint gait deficits, FES is commonly used only for the correction of swing-phase foot drop. Ankle plantarflexor muscles play an important role during gait. The aim of the current study was to test the immediate effects of delivering FES to both ank...

The purpose of this investigation was to determine if stereotypical patterns of gait initiation are altered in those with posttraumatic ankle osteoarthritis. Ten subjects, five with unilateral ankle osteoarthritis and five uninjured controls, participated. Subjects completed the SF-36 and Ankle Osteoarthritis Scale to quantify self-reported disability as well as 10 dual-limb static stance trial...

Introduction Cerebral palsy patients exhibit several variations from the normal gait pattern, when the kinematic and kinetic information is analyzed [1]. Electromyography (EMG) is frequently applied in such patients during gait, in order to supply information about the activation patterns of the involved muscles. In normal gait, the co-contraction of the knee extensor and flexor muscles is incr...

Capturing gait is useful for many applications, including video-surveillance and medical purposes. The most common sensors used to capture gait suffer from significant drawbacks. We have therefore designed a new low-cost and nonintrusive system to capture gait. Our system is able to track the feet on the horizontal plane in both the stance and the swing phases by combining measures of several r...

Introduction: Knowledge of accurate in-vivo kinematics of total hip arthroplasty (THA) during daily activities is critical for gaining insights into complications such as hip impingement, edge loading, wear and implant loosening. Previous studies have reported hip separations up to 3 mm in patients with metal-on-polyethylene (MoP) THA during the swing phase of gait. However, no studies evaluate...

Van Wezel, B.M.H., B.G.M. Van Engelen, F.J.M. Gabreëls, A.A.W.M. Gabreëls-Festen, and J. Duysens. Ab fibers mediate cutaneous reflexes during human walking. J. Neurophysiol. 83: 2980–2986, 2000. During human gait, transmission of cutaneous reflexes from the foot is controlled specifically according to the phase of the step cycle. These reflex responses can be evoked by nonnociceptive stimuli, a...
