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/OBJECTIVE We present a 3-dimensional biomechanical model of the upper extremities to characterize joint dynamics during 2 patterns of Lofstrand crutch-assisted gait in children with myelomeningocele. The upper extremity model incorporates recommendations by the International Society of Biomechanics. METHODS A Vicon motion analysis system (14 cameras) captured the marker patterns. I...

BACKGROUND Gait speed is a quick, inexpensive, reliable measure of functional capacity with well-documented predictive value for major health-related outcomes. Numerous epidemiological studies have documented gait speed in healthy, community-dwelling older people. The purpose of this study is to undertake a systematic review and meta-analysis of gait speed in a specific group with mobility limi...

This article describes a new multivariate measure of overall gait pathology called the Gait Deviation Index (GDI). The first step in developing the GDI was to use kinematic data from a large number of walking strides to derive a set of mutually independent joint rotation patterns that efficiently describe gait. These patterns are called gait features. Linear combinations of the first 15 gait fe...

A relationship between decline in mobility and walking performance and cognitive impairment exists in the elderly. Therefore, clinical assessment of gait and mobility may be relevant for diagnostic and therapeutic purposes. However, the rating scales used for evaluation of gait disorder in the context of cognitive deterioration were not designed or validated for that setting. The present study ...

The objective of this study was to compare the effects of conventional over-ground gait training with treadmill training on the restoration of gait in people with hemiparesis following a stroke. Twenty-five individuals in the early stages of rehabilitation were alternately assigned to one of two treatment groups. In addition to conventional physical therapy, the experimental group participated ...

We introduce the Movement Deviation Profile (MDP), which is a single curve showing the deviation of an individual's movement from normality. Joint angles, recorded from typically developing children over one gait cycle, were used to train a self-organizing map (SOM) which then generated MDP curves for patients with gait problems. The mean MDP over the gait cycle showed a high correlation (r(2) ...

Multiple sclerosis (MS) has a multifactorial etiology located at the interaction point of environmental factors--nutritional, geographic, infectious, etc.--with genetic factors, which confers susceptibility to disease or alters its development. This research presents a case study focused on complex assessment of a patient using clinical and functional assessment, biomechanical gait evaluation u...

BACKGROUND Aortic stenosis (AS) is a structural heart disease primarily associated with ageing. For people with multiple co-morbidities, surgical treatment may not be a safe or feasible option. Transcatheter aortic valve implantation (TAVI) is indicated for patients with symptomatic AS who are at excessive risk for surgical valve replacement and are likely to derive significant benefit. Functio...

A functional assessment of hand flapping exhibited by a 5-year-old boy was conducted in a general education classroom. After a descriptive analysis ruled out several potential variables maintaining hand flapping, an experimental analysis was used to test the hypothesis that teacher-delivered task demands were functionally related to hand flapping. Results of the experimental analysis were used ...
