BACKGROUND Walking dysfunctions persist following poststroke rehabilitation. A major limitation of current rehabilitation efforts is the inability to identify modifiable deficits that, when improved, will result in the recovery of walking function. Previous studies have relied on cross-sectional analyses to identify deficits to target during walking rehabilitation; however, these studies did no...

People are relatively insensitive to the curvature of their walking trajectory [Kallie et al., 2007, JEP:HPP, 33(1), 183-200]. This is exploited in the 'Redirected Walking' technique which is used in Virtual Reality to extend the borders of Virtual Environments (VE) beyond the size of the physical walking area [Steinicke et al., 2009, Journal of Virtual Reality and Broadcasting, 6(2009)]. One m...

BACKGROUND Walking speed is central to emerging consensus definitions of sarcopenia and frailty as well as being a major predictor of future health outcomes in its own right. However, measurement is not always feasible in clinical settings. We hypothesized that self-reported walking speed might be a good marker of objectively measured walking speed for use in this context. METHODS We investig...

Purpose: Considering the influence of horizontal velocity on many biomechanical characteristics of walking, the purpose of this study was to investigate how inter-lower-limbs local and global asymmetry is influenced by changes in walking speed from slow to fast. Methods: Ground reaction force data and trajectory of attached markers of bilateral lower limbs of 15 right leg-dominant able-bodied ...

Postprandial hypotension (PPH), a fall in systolic blood pressure (SBP) within 2 h of a meal, may detrimentally affect gait parameters and increase the falls risk in older people. We aimed to determine the effects of postprandial SBP on heart rate (HR), gait speed, and stride length, double-support time and swing time variability in older subjects with and without PPH. Twenty-nine subjects were...

The impact of electronic dipole tags on the walking activity of three insects was determined using video tracking software. Results varied within and between the three species studied. The heaviest tag mounted on the pronotum of the Colorado potato beetle, Leptinotarsa decemlineata (Say), reduced its mean horizontal speed slightly but significantly. The mean horizontal speed of plum curculio, C...

To understand the physical and other factors related to walking among the elderly residents of a Care House for the aged, the total number of steps walked were measured over a period of 1 week (Nov. 6-12. 1994) for 67 female residents (mean age 79 ± 1 years). In addition, walking speed, stride length, and the time to climb 15 steps (stair-climbing time) were measured. To understand the indirect...

QUESTION Which measures of activity limitation on admission to rehabilitation after stroke best predict walking speed at discharge? DESIGN Prospective observational study. PARTICIPANTS 120 people with stroke undergoing inpatient rehabilitation. OUTCOME MEASURES Predictors were admission walking speed, Timed Up and Go, Motor Assessment Scale, Modified Elderly Mobility Scale, and Functional...

This study investigated some aspects of the validity of walking speed recording in 15 normal subjects, 16 trans-femoral amputees and 8 knee disarticulation amputees . The variability and test-retest reliability of walking speed and the influence of simultaneous recording of E M G and goniometry on comfortable and fast walking speeds were studied. The variability between sessions was mainly dete...
