“…Therefore, it can be stated that increasing uninterrupted gait through a longer walking length and/or a reduced requirement to turn, results in reduced spatial gait variability, confirming the second hypothesis. This implies future investigations aiming to assess gait variability should employ continuous walking path configurations, such as those stated in literature and employed in the current study (15M and FIG8), in order to obtain more reliable and valid estimates of gait variability [14].…”

“…No agreement exists on the recommendation for the minimum number of gait cycles required for reliable gait variability assessment, suggesting that gait variability is influenced by the duration of a walking trial and/or number of strides recorded [13][14][15]. Although spatial measures of gait variability seemed to be consistent across the 6MWT duration, temporal measures were clearly influenced in the early stages of the 6MWT.…”

“…Adaptation to walking path configuration has also been shown to influence gait variability, with repeated single walking path trials displaying increased variability vs. continuous walking trials [12], perhaps due to the variability in the acceleration vs. steady-state phase of walking gait [13]. In order to ameliorate these issues, continuous overground walking path protocols, such as the 'figure of eight', have been proposed [14]. Currently, there is no agreement on the minimum number of gait cycles to recommend for reliable gait variability assessment, indicating that gait variability is also affected by the stride count and/or duration of a walking trial [13][14][15].…”

The current study determined whether manipulations to walking path configuration influenced six-minute walk test (6MWT) outcomes and assessed how gait variability changes over the duration of the 6MWT in different walking path configurations. Healthy older (ODR) and younger (YNG) (n=24) adults completed familiarisation trials and five randomly ordered experimental trials of the 6MWT with walking configurations of; 5M, 10M and 15M straight lines, a 6m by 3m rectangle (RECT), and a figure of eight (FIG8). Six-minute walk distance (6MWD) and walking speed (m.s -1 ) were recorded for all trials and the stride count recorded for experimental trials. Reflective markers were attached to the sacrum and feet with kinematic data recorded at 100Hz by a nine-camera motion capture system for 5M, 15M and FIG8 trials, in order to calculate variability in stride and step length, stride width, stride and step time and double limb support time. Walking speeds and 6MWD were greatest in the 15M and FIG8 experimental trials in both groups (p<0.01).Step length and stride width variability were consistent over the 6MWT duration but greater in the 5M trial vs. the 15M and FIG8 trials (p<0.05). Stride and step time and double limb support time variability all reduced between 10 and 30 strides (p<0.01). Stride and step time variability were greater in the 5M vs. 15M and FIG8 trials (p<0.01). Increasing uninterrupted gait and walking path length results in improved 6MWT outcomes and decreased gait variability in older and younger adults.

“…The decrease of the stride length is associated with falls in men aged above 74 years, but not in women in that same age range, nor in men and women aged between 65-74 years 4 . In the present study, the functional measures of step length, stride length and velocity decreased with age, while the measures of stability (stance, double support and pre-swing time) increased with age, aiming at stability to reduce falls risk 34,35 . The double support measure was directly related to age after 50 years (R = 0.48 and p = 0/010 to the right and R = 0.60 and p<0.001 to the left), which is compatible with LaRoche et al 36 .…”

ObjectiveGait impairment is common in patients with cerebral small vessel disease (SVD). However, gait studies in elderly SVD patients might be confounded by age‐related comorbidities, such as polyneuropathy or sarcopenia. We therefore studied young patients with the genetically defined SVD CADASIL. Our aim was to examine the effects of pure SVD on single and dual task gait, and to investigate associations of gait performance with cognitive deficits and white matter alterations.MethodsWe investigated single task walking and calculatory, semantic, or motoric dual task costs in 39 CADASIL patients (mean age 50 ± 8) using a computerized walkway. We obtained 3.0T MRI and neuropsychological data on processing speed, the main cognitive deficit in CADASIL. Spatiotemporal gait parameters were standardized based on data from 192 healthy controls. Associations between white matter integrity, assessed by diffusion tensor imaging, and gait were analyzed using both a global marker and voxel‐wise analysis.ResultsCompared to controls, CADASIL patients showed only mild single task gait impairment, and only in the rhythm domain. The semantic dual task additionally uncovered mild deficits in the pace domain. Processing speed was not associated with gait. White matter alterations were related to single task stride length but not to dual task performance.InterpretationDespite severe disease burden, gait performance in patients with pure small vessel disease was relatively preserved in single and dual tasks. Results suggest that age‐related pathologies other than small vessel disease might play a role for gait impairment in elderly SVD patients.
