Figure 1
A model of gait for people with MS. A principal component analysis of 21 gait parameters with varimax rotation produced 6 orthogonal domains of gait. Factor loadings were considered relevant at > 0.50 and are bolded. Factor loadings are listed in order of importance. The values in the circles represent the proportion of total variance explained by each domain. %h percent of height; % GC percent of the gait cycle; ML mediolateral, AP anterior–posterior; variability was calculated using the coefficient of variation.
