OBJECTIVE: To examine the association between Multiple Sclerosis Walking Scale-12
(MSWS-12) scores and spatiotemporal parameters of gait as indicators of gait
quality among ambulatory persons with multiple sclerosis (MS). DESIGN:
Cross-sectional study. SETTING: University research laboratory. PARTICIPANTS:
Community-residing persons with MS (N=268). INTERVENTION:
Not applicable.
OUTCOME MEASURES: Main outcome measures included the MSWS-12 and spatial and
temporal gait parameters (walking speed, cadence, step length, step time, base of
support [ie, the distance between 1 footfall and the line of progression of the
opposing foot], and percentage of gait cycle spent in double support). Secondary
outcomes included the timed 25-foot walk (T25FW), 6-minute walk (6MW), and
Patient-Determined Disease Steps scale. RESULTS:
MSWS-12 scores were
significantly correlated with walking speed (r=-.59), cadence (r=-.50), step
length (r=-.53), step time (r=.46), base of support (r=.29), and percentage of
the gait cycle spent in double support (r=.54). MSWS-12 scores further were
significantly correlated with T25FW (r=.57) and 6MW (r=-.75) scores. CONCLUSIONS:
Such findings suggest that the MSWS-12 captures aspects of walking quality,
assessed as spatiotemporal parameters of gait, in addition to walking speed and
endurance in persons with MS.
