Nonlinear dynamics quantifies gait variability patterns, which can be useful in evaluating functional ability. A commonly used nonlinear technique is detrended fluctuation analysis (DFA). Safety support structures have previously been shown to alter DFA during gait. However, the effect of a nonweight-supporting treadmill harness on DFA during gait has yet to be determined. The purpose of this s...

Purpose. To test the effects of a physical-cognitive exercise intervention on gait parameters under dualtask conditions in community-dwelling older adults. Design. A repeated-measures quasi-experimental design, with control and exercise groups, was used. Setting. Study participants consist of a convenience sample recruited from senior citizens’ centers in Monterrey, Mexico. Subjects. A total of...

The relationships between litter moisture, footpad dermatitis (FPD) and pain in medium-heavy turkey strains was studied by gait analysis in two medium-heavy with and without analgesia (betamethasone or bupivacaine). The relationship between FPD and litter moisture was linear above a breakpoint of 49% litter moisture, and there were no differences between the two breeds in susceptibility to FPD....

This study tested whether the lower economy of walking in healthy elderly subjects is due to greater gait instability. We compared the energy cost of walking and gait instability (assessed by stride to stride changes in the stride time) in octogenarians (G80, n = 10), 65-yr-olds (G65, n = 10), and young controls (G25, n = 10) walking on a treadmill at six different speeds. The energy cost of wa...

Despite a large number of studies that have considered footstrike pattern, relatively little is known about how runners alter their footstrike pattern with running velocity. The purpose of this study was to determine how footstrike pattern, defined by footstrike angle (FSA), is affected by running velocity in recreational athletes. One hundred and two recreational athletes ran on a treadmill at...

Motivated by the training of Generative Adversarial Networks (GANs), we study methods for solving minimax problems with additional nonsmooth regularizers. We do so employing \emph{monotone operator} theory, in particular \emph{Forward-Backward-Forward (FBF)} method, which avoids known issue limit cycling correcting each update a second gradient evaluation. Furthermore, propose seemingly new sch...

BACKGROUND fear of falling (FoF) has great impact on functioning and quality of life of older people, but its effects on gait and balance are largely unknown. METHODS we examined FoF in 100 participants aged >or=75 years, using the Activities-specific Balance Confidence scale. Participants with a mean score <67% were assigned to the FoF group. We quantified gait and balance during walking at ...
