- Abstract
Patients with multiple sclerosis (MS) present with varying symptoms that can differ between and within individuals. As new interventions and drug treatments become available to MS patients, it is essential to understand the relationship between fatigue and the variability of functional mobility measures in order to define a meaningful change due to treatment within the MS population. The purpose of this study was to examine the within-day and between-day changes in gait variability for subjects with MS in fresh and fatigued conditions. Walking gait parameters were measured from 20 subjects diagnosed with MS and eight healthy control subjects. Standard deviations of hip, knee and ankle kinematic and kinetic variables were quantified as the measure of variability and analysed with a two-way (group by condition) ANOVA. Results indicated MS subjects had significantly greater hip (P<0.020), knee (P<0.011) and ankle (P<0.034) joint angle variability than control subjects, but variability was not different between conditions. Kinetic variability was not different between groups or conditions. MS subjects in this study walked more slowly than the healthy controls and they also reported more fatigue. Research examining treatment effects within the MS population should account for increased levels of kinematic gait variability.
