We study the problem of analyzing and classifying frontal view gait video data. In this study, we suppose that frontal view gait data as a mixing of scale changing, human movements and speed changing parameters. We estimate these parameters using the statistical registration and modeling on a video data. Our gait model is based on human gait structure and temporal-spatial relations between came...

Objectives: This paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. The objective was to control the ankle hysteresis at slow and normal walking speeds. Methods: Inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for...

BACKGROUND Osteoarthritis of the knee is related to many correlated mechanical factors that can be measured with gait analysis. Gait analysis results in large data sets. The analysis of these data is difficult due to the correlated, multidimensional nature of the measures. METHODS A multidimensional model that uses two multivariate statistical techniques, principal component analysis and disc...

Gait analysis has a long history and tradition, from the pioneering work of Muybridge and Inman continuing through contemporary times with the development of modern computer-based analysis systems capable of describing the kinematic, kinetic, and muscle activation patterns of gait in unusually rich detail . Over the past several decades, instrumented gait analysis has emerged as a powerful tool...

Medical scholarship about gait disorders blossomed in the nineteenth century: locomotor ataxia in tabetic neurosyphilis (Romberg, Gowers, and Charcot); the festinating gait of Parkinson’s disease, and so many others. In the same time appeared the measurement of locomotion in the modern sense: firstly by applying photography (Muybridge), and secondly by combining kinematic and kinetic locomotor ...

The objective of this study was to measure gait abnormalities in elderly fallers with the LocometrixTM gait-analysis system. This accelerometric device provided the following gait variables: walking speed and stride frequency, length, symmetry, and regularity. The variables were analyzed over a 20-s period of stable walking on a flat track of 40 m. Participants were 20 elderly patients hospital...

Mobility has been measured in the form of gait analysis – a method used to assess the physical functioning of a human. Many health-related clinical and pathological gait analysis applications have been proposed in the last decades. Gait analysis research has been predominantly conducted in laboratories in a discipline-specific manner. The main measurement approach is to monitor intrinsic gait p...

Complex gait analysis systems are not generally available worldwide, and no simple system of assessing gait by observation has been validated specifically for use in patients with cerebral palsy. The authors have developed a visual gait analysis score for use in cerebral palsy. Videotaped sequences of patients were recorded before and after surgery as part of a three-dimensional gait study usin...

A conventional feedback-linearization-based controller, when applied to a tiltrotor (eight inputs), results in extensive changes tilting angles, which are not expected practice. To solve this problem, we introduce the novel concept of “UAV gait” restrict angles. The gait plan was initially used control problems quadruped (four-legged) robots. Applying approach, accompanied by feedback lineariza...

STUDY DESIGN Gait analysis of patients with cervical spondylotic myelopathy (CSM) by using a sheet-type gait analysis system. PURPOSE The aim of this study was to compare the gait patterns of patients with CSM, evaluated by the Nurick grades, and to determine the threshold values of gait parameters predicting the occurrence of a fall by using a gait recorder. OVERVIEW OF LITERATURE Gait dis...
