BACKGROUND Assessment of children treated nonoperatively for idiopathic clubfoot, has primarily focused on the kinematic and kinetic results measured with gait analysis (GA). Excellent results in ankle motion and push-off power during gait have been reported at age 5; however, the assessment of gross motor function, has not been evaluated. The purpose of this study was to look at the relationsh...

PURPOSE This study introduces a novel way to accurately assess gait quality. This new method called Multifeature Gait Score (MGS) is based on the computation of multiple parameters characterizing six aspects of gait (temporal, amplitude, variability, regularity, symmetry and complexity) quantified with one inertial sensor. According to the aspects described, parameters were aggregated into part...

Gait measures are used to evaluate change in patients with knee osteoarthritis (OA), but reliability has not been fully established in this population. This study examined test-retest reliability of knee angle and moment gait waveform characteristics captured using discrete parameters and principal component analysis (PCA) in individuals with moderate knee OA. Participants (n=20) underwent thre...

The clinical impact of Alzheimer's disease pathology at biopsy was investigated in 56 cognitively impaired patients undergoing shunt surgery for idiopathic normal pressure hydrocephalus (NPH). Cognition was measured by means of the global deterioration scale (GDS), the mini mental status examination (MMSE) and a battery of six psychometric tests. Gait was assessed using objective measurements o...

introduction: the most common manifestation of disturbed neurological function following stroke is motor weakness. muscle weakness has been implicated as a factor underlying deficits in gait performance in subjects who have suffered strokes . the purpose of this study was to investigate the relationship between involved lower extremity isometric muscle strength and two functional tasks: gait ab...

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...

The clinical impact of Alzheimer’s disease pathology at biopsy was investigated in 56 cognitively impaired patients undergoing shunt surgery for idiopathic normal pressure hydrocephalus (NPH). Cognition was measured by means of the global deterioration scale (GDS), the mini mental status examination (MMSE) and a battery of six psychometric tests.

OBJECTIVE To investigate the association between knee pain during gait and 4 clinical phenotypes based on static varus alignment and varus thrust in patients with medial knee osteoarthritis (OA). METHODS Patients in an orthopedic clinic (n = 266) diagnosed as having knee OA (Kellgren/Lawrence [K/L] grade ≥1) were divided into 4 phenotype groups according to the presence or absence of static v...

This paper reviews recent research on lameness in dairy cows, with special focus on our work at the University of British Columbia addressing the scientific assessment of impaired gait, and how such impairments can be prevented through improvements in housing. Subjective gait scores can vary considerably between observers, but the reliability of these scores can be much improved with training a...

The reduction and analysis of gait waveform data is a signi®cant barrier to the clinical application of gait analysis. Principal component modelling of gait waveform data reduced the waveform data to measures of distance from normal and these distance measures were shown to be sensitive to changes in gait pattern associated with knee osteoarthritis and its treatment by unicompartmental arthropl...
