This paper describes a method of gait recognition by suppressing and using gait fluctuations. Inconsistent phasing between a matching pair of gait image sequences because of temporal fluctuations degrades the performance of gait recognition. We remove the temporal fluctuations by generating a phase-normalized gait image sequence with equal phase intervals. If inter-period gait fluctuations with...

This paper describes the application of Particle Swarm Optimization (PSO) for gait optimization on a humanoid robot. The biped gait is modeled by a number of parameterizable trajectories. To achieve omni-directional walking, different sets of gait parameters are optimized for specific walk directions and interpolated later. By using a fitness test based on an acceleration walk, the optimized se...

For physical therapists observational gait assessment is preferable to instrumented gait assessment in the clinical setting. Existing observational gait assessment tools used in clinical practice were reviewed in terms of their validity, repeatability, sensitivity, and specificity. Most gait assessment tools lacked information concerning their validity or repeatability. In addition, most gait a...

Aims: Amputation makes a person susceptible to postural deviation and compensatory movements and causes reduced performance, biocompatibility, pain, and dissatisfaction. The purpose of this study was to investigate the effect of eight weeks of a comprehensive rehabilitation protocol on indicators of postural control, back pain, quality of life, and gait speed in adults with unilateral lower lim...

objectives: stroke is one of the most common neurological disease and it is the main cause of physical and mental disability and staying in house. gait difficulties have high incidence in patients with stroke. so the aim of this study was to investigate the effect of gait retraining on balance, activities of daily living, quality of life and depressionin stroke patients. methods: this study was...

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...

The analysis of gait initiation (the transient state between standing and walking) is an important diagnostic tool to study pathologic gait and to evaluate prosthetic devices. While past studies have quantified mechanical energy of the body during steady-state gait, to date no one has computed the mechanical energy of the body during gait initiation. In this study, gait initiation in seven norm...

This paper presents work on the gait and gait transition analysis for a novel mobile robot that uses two actuated spoke wheels. Gait transitions, known as acyclic feed forward patterns, allow the robot to switch from one type of gait to another during walking and turning. The mobile robot IMPASS (Intelligent Mobility Platform with Active Spoke System) uses a unique mobility concept for locomoti...

Gait is an important health indicator and poor gait is strongly associated with disability and risk of falls. Thyroid dysfunction is suggested as a potential determinant of gait deterioration, but this has not been explored in a population-based study. We therefore investigated the association of thyroid function with gait patterns in 2645 participants from the Rotterdam Study with data availab...
