TLDR
The ability to control dynamic stability during perturbed walking by enlarging the base of support has already begun to deteriorate by middle age, and the valid agreement between kinematic models shows that such differences can be assessed by using just four body markers.About:

Steps to Take to Enhance Gait Stability: The Effect of Stride Frequency, Stride Length, and Walking Speed on Local Dynamic Stability and Margins of Stability
TL;DR: It is concluded that adaptations in stride frequency, stride length and/or walking speed can result in an increase of the medio-lateral and backward margins of stability, while these adaptations do not seem to affect local dynamic stability.
Journal ArticleDOI
Perturbation-based balance training for falls reduction among older adults: Current evidence and implications for clinical practice
TL;DR: A systematic search of recent PBT studies showed a significant reduction of falls incidence among healthy older adults and certain patient groups (e.g. people with Parkinson's disease and stroke), with clinically relevant reductions in frail older adults.

A systematic review of gait perturbation paradigms for improving reactive stepping responses and falls risk among healthy older adults
Christopher McCrum,Christopher McCrum,Marissa H G Gerards,Kiros Karamanidis,Kiros Karamanidis,Wiebren Zijlstra,Kenneth Meijer +6 more
TL;DR: A range of perturbation paradigms have been used successfully to perturb older adults’ gait and stimulate reactive response adaptations, andVariation also exists in the number and magnitudes of applied perturbations.

The effects of unexpected mechanical perturbations during treadmill walking on spatiotemporal gait parameters, and the dynamic stability measures by which to quantify postural response.
Forough Madehkhaksar,Jochen Klenk,Kim Sczuka,Katharina Gordt,Katharina Gordt,Itshak Melzer,Michael Schwenk,Michael Schwenk +7 more
TL;DR: Overall, participants walked with a shorter stride length, a wider step width, and a higher cadence during perturbed walking, but despite this, the effect of perturbations on means of SW and MoS-ML was not statistically significant.
Journal ArticleDOI
Analysis of biases in dynamic margins of stability introduced by the use of simplified center of mass estimates during walking and turning
TL;DR: The findings suggest that the lower extremity and trunk model and the pelvis average model should be considered in future studies to minimize bias when simplified models of CoM dynamics are desired.

Measuring agreement in method comparison studies
J M Bland,Douglas G. Altman +1 more
TL;DR: The 95% limits of agreement, estimated by mean difference 1.96 standard deviation of the differences, provide an interval within which 95% of differences between measurements by the two methods are expected to lie.
Journal ArticleDOI
The condition for dynamic stability
TL;DR: The well-known condition for standing stability in static situations is that the vertical projection of the centre of mass should be within the base of support (BoS), and an extension of this rule is proposed for dynamical situations.

Falls by elderly people at home: prevalence and associated factors.
A. J. Blake,Kevin Morgan,M. J. Bendall,H. Dallosso,Shah Ebrahim,T. H. D. Arie,P. H. Fentem,E. J. Bassey +7 more
TL;DR: Discriminant analysis of selected medical and anthropometric variables indicated that handgrip strength in the dominant hand and reported symptoms of arthritis, giddiness and foot difficulties were most influential in predicting reports of recent falls.

A fortran package for generalized, cross-validatory spline smoothing and differentiation
TL;DR: A subroutine package is presented in which the amount of smoothing on a set of n noisy datapoints is determined from the data by means of the Generalized Cross-Validation or predicted Mean-Squared Error criteria of Wahba and her collaborators.

Center of mass velocity-position predictions for balance control
Yi-Chung Pai,James L. Patton +1 more
TL;DR: These findings expand the long-held concept that balance is based on CM position limits (i.e. the horizontal CM position has to be confined within the BOS to guarantee stable standing) to a concept based onCM velocity-position limits.
