Comparison of gait patterns in elderly fallers and non-fallers.
TLDR
Results suggest that spatio-temporal variables and GRF variables would be useful for distinguishing prospective fallers from non-fallers among the elderly.Abstract:
Gait is associated with an important risk factor of falls in the elderly. It is important to find differences of quantitative gait variables between fallers and non-fallers. The aim of this study was to investigate gait patterns in elderly fallers and non-fallers. Thirty-eight fallers and 38 non-fallers of similar age and height participated in this study. Subjects walked across the GaitRite walkway at self-selected comfortable speeds. Spatio-temporal gait variables were measured to characterize gait patterns. Kinetic variables were derived from normalized vertical ground reaction force (GRF). Independent t-tests were performed to compare the fallers with the non-fallers. The fallers walked more slowly with shorter steps and more variable step times than the non-fallers (p< 0.05). The fallers showed a longer stance phase with increased double-limb support than the non-fallers (p< 0.05). The times to reach maximal weight acceptance and mid-stance of the fallers were significantly longer than those of the non-fallers (p< 0.05). These results suggest that spatio-temporal variables and GRF variables would be useful for distinguishing prospective fallers from non-fallers among the elderly.read more

TL;DR: Results suggest that the CSFTT for InPH patients might improve the so-called balance-related gait parameter (ie, step width) as well, and association between FAB scores and both stride time and stride length variability suggests involvement of similar circuits producing gait variability and frontal lobe functions in INPH patients.

A comparison of turn and straight walking phases as predictors of incident falls.
TL;DR: Gait variables collected during turning and walking straight were similar in their predictions of future falls, and clinical research that builds on these findings could improve identification and prevention of falls.

TL;DR: This study investigated whether fast-paced and dual-task walking uncover deficits in gait and turning not seen under single-task, whether cognitive and gait outcomes relate to fall incidence, and whether gait deficits measured with wearable inertial sensors correlate with motor symptom severity in HD as measured by the Unified Huntington’s disease Rating Scale-total motor score (UHDRS-TMS.

TL;DR: It is demonstrated that strike-interval fluctuations are more random (i.e., less correlated) in elderly subjects and in subjects with Huntington's disease, which are apparently associated with changes in central nervous system control.

TL;DR: Quantitative gait markers are independent predictors of falls in older adults and should be further studied to improve current fall risk assessments and to develop new interventions.
