Discrimination of stance and swing phases of the gait is required for control of functional e!ectrical stimulation (FES) used to assist with ankle dorsiflexion in foot-drop problem. Simple thresholds applied to a human, whole nerve signal processed using a sophisticated digital signal processing technique did not result in a safe and reliable control method. In this preliminary study, we use th...

OBJECTIVE To investigate the relationship between white matter abnormalities and impairment of gait and balance in older persons. METHODS Quantitative MRI was used to evaluate the brain tissue compartments of 28 older individuals separated into normal and impaired groups on the basis of mobility performance testing using the Short Physical Performance Battery. In addition, individuals were te...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

Ataxic gait monitoring and assessment of neurological disorders belong to important multidisciplinary areas that are supported by digital signal processing methods machine learning tools. This paper presents the possibility using accelerometric data optimise deep convolutional neural network systems distinguish between ataxic normal gait. The experimental dataset includes 860 segments 16 patien...

A 35-year-old, previously healthy man presented psychiatric symptoms lasting four years, receiving treatment with neuroleptics. One year later he evolved with gait disequilibrium. After a further six months, cognitive symptoms were characterized with rapid evolution to a profound demented state. MRI showed signal changes in cerebral white matter and very long-chain fatty acids were detected in ...

Disabilities affecting mobility, in particular, often lead to exacerbated isolation and thus fewer communication opportunities, resulting in a limited participation in social life. Additionally, as costs for the health-care system can be huge, rehabilitation-related devices and lower-limb prostheses (or orthoses) have been intensively studied so far. However, although many devices are now avail...

background: in this study we investigated the differences of functional gait and balance measures between patients with chronic stroke with different level of concern about falling. methods: fifty-four patients with chronic stroke participated in this observational, cross-sectional study. the level of concern relating to falls was assessed by using the falls efficacy scale-international. thirty...

Wavelets-Based Fractals in Gait Metin Akay School of Engineering Dartmouth College In this study, we attempt to classify the acceleration signals for walking along a corridor and on stairs by using the wavelet-based fractal analysis method. In addition, the wavelet-based fractal analysis method was used to evaluate the gait of elderly subjects and patients with Parkinson’s disease. The triaxial...
