Gait Speed and Survival in Older Adults [PDF]

JAMA, 2011
Survival estimates help individualize goals of care for geriatric patients, but life tables fail to account for the great variability in survival. Physical performance measures, such as gait speed, might help account for variability, allowing clinicians to make more individualized estimates.To evaluate the relationship between gait speed and survival ...

Gait Variability at Different Walking Speeds

Journal of Functional Morphology and Kinesiology, 2023
Gait variability (GV) is a crucial measure of inconsistency of muscular activities or body seg-mental movements during repeated tasks. Hence, GV might serve as a relevant and sensitive measure to quantify adjustments of walking control. However, has not been clarified whether GV is associated with walking speed to exploit effective better coordination ...

Association between daily gait speed patterns and cognitive impairment in community-dwelling older adults

Scientific Reports, 2023
Gait speed over a short distance is associated with cognitive impairment in older adults. Recently, daily gait speed has been assessed using accelerometers.

Optimal Cut-Off Points of 4-meter Gait Speed to Discriminate Functional Exercise Capacity and Health Status in Older patients with Chronic Obstructive Pulmonary Disease [PDF]

Annals of Geriatric Medicine and Research, 2022
Background Gait speed, a vital sign of health and functional capacity, is commonly used to measure mobility. Although studies have assessed gait speed in older adults and individuals with chronic obstructive pulmonary disease (COPD) separately, few have ...

A Behavioral Mechanism of How Increases in Leg Strength Improve Old Adults’ Gait Speed [PDF]

, 2014
We examined a behavioral mechanism of how increases in leg strength improve healthy old adults’ gait speed. Leg press strength training improved maximal leg press load 40% (p = 0.001) and isometric strength in 5 group of leg muscles 32% (p = 0.001) in a ...

Does Gait Speed Replace Comprehensive Geriatric Assessment in the Elderly?

International Journal of Gerontology, 2016
Background: Ageing is associated with generalized slowing of movement. Gait speed is an indicator of physical performance. The present study aimed to determine whether the gait speed could replace the comprehensive geriatric assessment (CGA) to assess ...

Effects of three types of exercise interventions on healthy old adults’ gait speed: A systematic review and meta-analysis [PDF]

, 2015
Background Habitual walking speed predicts many clinical conditions later in life, but it declines with age. However, which particular exercise intervention can minimize the age-related gait speed loss is unclear.

Principal Motion Ellipsoid: Gait variability index invariant with gait speed [PDF]

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2020
The walking motion of an individual involves considerable variability. We develop a gait variability index that determines how and to what degree repeated human gait motions vary, based on generalized principal motion analysis (GPMA). Principal motion analysis (PMA) is an extension of principal component analysis and decomposes multivariate time-series

Gait Recognition under Speed Transition [PDF]

2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
This paper describes a method of gait recognition from image sequences wherein a subject is accelerating or decelerating. As a speed change occurs due to a change of pitch (the first-order derivative of a phase, namely, a gait stance) and/or stride, we model this speed change using a cylindrical manifold whose azimuth and height corresponds to the ...
