The effect of sex on measures of foot mobility and stiffness in children and adolescents

Foot mobility has been suggested to be an important consideration in the selection of footwear (Farndon, Robinson, Nicholls, & Vernon, 2016). In contrast to measures of static measures of foot structure, quasi-static measuresof foot mobility and stiffness have also been reported tobe useful predictors of injury and dynamic foot posture inadults (McPoil, Vicenzino, Cornwall, Collins, & Warren,2009; Zifchock, Davis, Hillstrom, & Song, 2006). However, relatively little is known about foot mobility and stiffness in children and whether the moderating effect of sex reported in adults (Zifchock et al., 2006) is also evident in children.
