A systematic review of center of pressure measures to quantify gait changes in older adults

Measures of gait center of pressure (COP) can be recorded using simple available technologies in clinical settings and thus can be used to characterize gait quality in older adults and its relationship to falls. The aim of this systematic review was …

Assessment of Parkinsonian gait in older adults with dementia via human pose tracking in video data

Background: Parkinsonism is common in people with dementia, and is associated with neurodegenerative and vascular changes in the brain, or with exposure to antipsychotic or other dopamine antagonist medications. The detection of parkinsonian changes …

Measuring Gait Variables Using Computer Vision to Assess Mobility and Fall Risk in Older Adults with Dementia

Fall risk is high for older adults with dementia. Gait impairment contributes to increased fall risk, and gait changes are common in people with dementia, although the reliable assessment of gait is challenging in this population. This study aimed to …

Predicting Short-Term Risk of Falls in a High-Risk Group With Dementia

Objectives: To develop a prognostic model to predict the probability of a short-term fall (within the next 7 to 30 days) in older adults with dementia. Design: Prospective observational study. Setting and Participants: Fifty-one individuals with …

Vision-Based Assessment of Gait Features Associated With Falls in People With Dementia

BACKGROUND: Gait impairments contribute to falls in people with dementia. In this study, we used a vision-based system to record episodes of walking over a 2-week period as participants moved naturally around their environment, and from these …

A robust method to estimate the largest Lyapunov exponent of noisy signals: A revision to the Rosenstein's algorithm

This study proposed a revision to the Rosenstein's method of numerical calculation of the largest Lyapunov exponent (LyE) to make it more robust to noise. To this aim, the effect of increasing number of initial neighboring points on the LyE value was …

Challenging Conventional Paradigms in Applied Sports Biomechanics Research

This paper evaluates the effectiveness of, and highlights issues with, conventional paradigms in applied sports biomechanics research and comments on their capacity to optimise techniques of individual athletes. In empirical studies, group-based …

Gait stability of diabetic patients is altered with the rigid rocker shoes

Background: Rigid-rocker shoes may induce gait instability in diabetics, however, is not clearly investigated. The present study investigates if rigid-rocker shoes influence diabetic gait stability. Methods: Fourteen non-neuropathic and nine …

Lower extremity kinematic analysis in male athletes with unilateral anterior cruciate reconstruction in a jump-landing task and its association with return to sport criteria

Background: Return to sport (RTS) criteria are widely being used to identify anterior cruciate ligament reconstructed (ACLR) athletes ready to return to sportive activity and reduce risk of ACL re-injury. However, studies show a high rate of ACL …

Order error in the calculation of continuous relative phase

© 2018 Elsevier Ltd The aims of this study were to demonstrate “order error” in the calculation of continuous relative phase (CRP) and to suggest two alternative methods—(i) constructing phase-plane portraits by plotting position over velocity; and …
