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...

OBJECTIVE Simple measures of gait for routine clinical use could be useful when the complex gait analysis systems are not available. The aim of this study was to quantify asymmetry in children with spastic hemiplegia using a two-dimensional gait analysis by videography and to relate the asymmetry to motor function. METHODS Twenty-four children with spastic hemiplegia (19 males, 5 females; mea...

BACKGROUND The Gillette Gait Index (GGI) is a summary measure incorporating 16 clinically important kinematic and temporal parameters. The purpose of this study was to compare GGI scores from computerized gait analysis versus qualitative visual assessments of overall gait to assess the validity of the GGI as a summary score for gait analysis. METHODS The GGI was calculated for 25 children wit...

BACKGROUND This study aimed to measure the gait abnormalities in GRMD (Golden retriever muscular dystrophy) dogs during growth and disease progression using an ambulatory gait analyzer (3D-accelerometers) as a possible tool to assess the effects of a therapeutic intervention. METHODS Six healthy and twelve GRMD dogs were evaluated twice monthly, from the age of two to nine months. The evoluti...

Purpose: It is essential to maintain dynamic stability during walking to perform daily tasks independently. The present study aimed at comparing the spatiotemporal parameters and the values of the vertical ground reaction force (vGRF) as well as determining the time to reach them in ankle-sprain coper and healthy athletes during the stance phase of gait. Methods: A total of 28 female universit...

PURPOSE Hemiplegia is a paralysis on one side of the body resulting from disease or injury to the motor centers of the brain that may lead to difficulty in walking and problems in balance. A new methodology for hemiplegia gait patterns classification based on bicluster analysis, which aims to identify a group of patients with similar gait patterns, and verify if spatial-temporal gait parameters...

The quantitative assessment of the change of gait symmetry has played a very important role in the clinical diagnostics. This paper investigated the application of an advanced hybrid machine learning approach such as the combining kernel-based principal component analysis (KPCA) with support vector machine (SVM) to evaluate the change of gait symmetry quantitatively based on the basic idea that...

INTRODUCTION Accelerometers are becoming an increasingly important tool in the study of human movement. Their ease and affordability, combined with the potential to collect large amounts of continuous data outside the laboratory setting makes them excellent tools for gait analysis. Research has demonstrated the effectiveness of a single tri-axial accelerometer in measuring mean spatiotemporal p...

Psychological studies indicate that people have a small but statistically significant ability to recognize the gaits of individuals that they know. Recently, there has been much interest in machine vision systems that can duplicate and improve upon this human ability for application to biometric identification. While gait has several attractive properties as a biometric (it is unobtrusive and c...
