Many falls in older adults occur during walking following trips. Following a trip, older adults take longer than younger adults to recover steady-state walking. Although faster gait speed may improve interlimb coordination, it may also increase fall risk in older adults. We hypothesized that older adults would take longer than younger adults to recover from an unexpected perturbation during gai...

This study compared the kinematic and electromyographic (EMG) gait patterns of able-bodied adults at natural speed in contrast to extremely slow overground and treadmill walking speeds. Kinematic and EMG data were collected at three speeds (self-selected, 0.30 m/s, and 0.20 m/s). Eighteen subjects were evaluated for trunk and lower-limb motion and EMG of five lower-limb muscles. Significant red...

OBJECTIVE To investigate the predictive value of gait speed for community walking in Parkinson's disease and to develop a multivariate prediction model for community walking. DESIGN Data from baseline assessments in a randomized clinical trial were used. SUBJECTS A total of 153 patients with Parkinson's disease were included. METHODS Community walking was evaluated using the mobility doma...

Gait and Balance Scale (GABS) consists of historical information and examination of 14 different gait and balance parameters designed to assess the severity of these functional domains. Thirty-five patients with Parkinson's disease (PD), Hoehn and Yahr stages 1-3, were tested during their "off" period. GABS items were compared to quantitative data from two computerized gait analysis instruments...

To test for an association between the LRRK2-G2019S mutation and gait, we studied 52 first-degree relatives of patients with Parkinson’s disease (PD) who carry this mutation. An accelerometer quantified gait during usualwalking, fast-walking, and dual-tasking. Noncarriers (n 1⁄4 27) and carriers (n1⁄4 25) were similar with respect to age, gender, height, and gait speed during all conditions. Du...

IMPORTANCE Cerebral white matter hyperintensities (WMHs) are involved in the evolution of impaired mobility and executive functions. Executive functions and mobility are also associated. Thus, WMHs may impair mobility directly, by disrupting mobility-related circuits, or indirectly, by disrupting circuits responsible for executive functions. Understanding the mechanisms underlying impaired mobi...

Objectives: Fear of falling (FOF) is a common complication after stroke affecting gait and balance performance in individuals with a history of stroke. The current study aimed at determining the influence of the level of FOF on gait and balance performance after chronic stroke. Methods: A total of 76 persons with chronic stroke (including 41 women), who had no cognitive impairment and could wa...
