Influence of number of strides analysed on mean kinematic symmetry indices

Asymmetry indices provide insights into walking mechanics in populations with unilateral deficiencies. The number of strides used in specific studies varies, and often there are equivocal outcomes for symmetry reported in the literature. Thus, it is worth understanding the influence of the number of strides that should be used to characterize symmetry. Eight strides were required to achieve a stable mean symmetry index; however, no significant differences were noted between three, five, and eight strides of walking.
