A comparison of the Euclidean distances of postural and focal muscle vectors from their mean. The Euclidean distances for the postural muscles were found to be significantly higher than that of the focal muscles in every condition (p<0.01, ANOVA, Tukey HSD posthoc). The higher Euclidean distance of the postural muscles demonstrates that their intra class variability was higher than that of the focal muscles.
