AIM Gait rehabilitation programs often require either partial weight-bearing (PWB) or encourage full weight-bearing (FWB) on the affected limb. Until recently, there was no objective and practical way to measure correct weight-bearing during ambulation. The present study evaluates a new in-shoe device (SmartStep, Andante Medical Devices Ltd.) for measuring the amount of weight on the affected l...

Gait recognition is an important biometric technique for video surveillance tasks, due to the advantage of using it at distance. In this paper, we present a persistent homology-based method to extract topological features (the so-called topological gait signature) from the the body silhouettes of a gait sequence. It has been used before in several conference papers of the same authors for human...

introduction: in this study, arrangement of a low-cost optical tomography device compared to other methods such as frequency domain diffuse tomography or time domain diffuse tomography is reported. this low-cost diffuse optical imaging technique is based on the detection of light after propagation in tissue. these detected signals are applied to predict the location of in-homogeneities inside p...

With ever-rising population comes a corresponding rise in people with mobility issues who have difficulty handling tasks their daily lives. Such persons could benefit significantly from an active movement assistance device. This paper presents the design of lower-limb exosuit designed to provide wearer useful gait assistance. While exoskeletons existed for while, soft or exosuits are relatively...

Gait patterns of humans and humanoid robots are often described by analysing changes in angular rotation of hip, knee and ankle joints during one gait cycle. Each joint displays specific behaviour and irregularities of the gait pattern could be detected by measuring displacements from the normal rotation curve, while small deviations of individual gait chara...

Background: The gait pattern after stroke can be disturbed by foot drop. The conventional approach to the treatment of drop foot gait is a splint, the ankle-foot orthosis (AFO). An active approach is functional electrical stimulation (FES). Functional electrical stimulation (FES) refers to electrical stimulation of muscles in order to improve the impaired motor function. This is achieved by act...

BACKGROUND Parkinson's disease is a progressive neurological disorder resulting from a degeneration of dopamine producing cells in the substantia nigra. Clinical symptoms typically affect gait pattern and motor performance. Evidence suggests that the use of individual auditory cueing devices may be used effectively for the management of gait and freezing in people with Parkinson's disease. The ...

BACKGROUND Alcohol ingestion influences sensory-motor function and the overall well-being of individuals. Detecting alcohol-induced impairments in gait in daily life necessitates a continuous and unobtrusive gait monitoring system. OBJECTIVES This paper introduces the development and use of a non-intrusive monitoring system to detect changes in gait induced by alcohol intoxication. METHODS ...

With the advent of the functional electrical stimulation (FES) technology and its application as a walking aid, the need emerged to detect accurately specific phases (events) in the human gait cycle in order to time the stimulation sequences applied to the muscles [1]. In the recent literature, several sensor combinations (foot switches [2,3,4], goniometers [3,4], tilt sensors [5], acceleromete...

BACKGROUND A well-established connection exists between increased gait variability and greater fall likelihood in Parkinson's disease (PD); however, a portable, validated means of quantifying gait variability (and testing the efficacy of any intervention) remains lacking. Furthermore, although rhythmic auditory cueing continues to receive attention as a promising gait therapy for PD, its widesp...
