In nature, many physical and biological systems have structures showing harmonic properties. Some of them were found related to the irrational number φ known as the golden ratio that has important symmetric and harmonic properties. In this study, the spatiotemporal gait parameters of 25 healthy subjects were analyzed using a stereophotogrammetric system(More)
In a dark environment, when vision is excluded, humans are usually able to walk towards a target the position of which was previously memorized. Changes in spatio-temporal gait parameters, the presence of obstacles on the ground or pathway tilt can affect their performances. The aim of this study was to investigate the influence of the environment on this(More)
BACKGROUND AND PURPOSE The goal of this study was to assess the specific influence of stroke etiology on rehabilitation results. METHODS This was a case-control study of 270 inpatients with sequelae of first stroke who were enrolled in homogeneous subgroups and matched for stroke severity, basal disability, age (within 1 year), sex, and onset admission(More)
OBJECTIVE Motor imagery (MI) is assumed to enhance poststroke motor recovery, yet its benefits are debatable. Brain-computer interfaces (BCIs) can provide instantaneous and quantitative measure of cerebral functions modulated by MI. The efficacy of BCI-monitored MI practice as add-on intervention to usual rehabilitation care was evaluated in a randomized(More)
Vision can improve bipedal upright stability during standing and affect spatiotemporal parameters during walking. However, little is known about the effects of visual deprivation on gait dynamic stability. We have tested 28 subjects during walking under two different visual conditions, full vision (FV) and no vision (NV), measuring their upper body(More)
The aim of this study was to quantitatively assess the stability and harmony of gait in children with cerebral palsy. Seventeen children with spastic hemiplegia due to cerebral palsy (5.0±2.3 years old) who were able to walk autonomously and seventeen age-matched children with typical development (5.7±2.5 years old, p=0.391) performed a 10-m walking test(More)
Control of gait is usually altered following stroke, and it may be further compromised by overexertion and fatigue. This study aims to quantitatively assess patients' gait stability during six-minute walking, measuring upper body accelerations of twenty patients with stroke (64 ± 13 years old) and ten age-matched healthy subjects (63 ± 10 years old).(More)
The effectiveness of neglect rehabilitation training has been studied in two randomly selected groups of right brain-damaged patients. All patients proved heminattentive on a standard battery 2 months or more after the CVA. One group received 2 months of treatment immediately after admission to a clinic, and the other group received only general cognitive(More)
Stroke is the leading cause of long-term disability for adults in industrialized societies. Rehabilitation's efforts are tended to avoid long-term impairments, but, actually, the rehabilitative outcomes are still poor. Novel tools based on new technologies have been developed to improve the motor recovery. In this paper, we have taken into account seven(More)
