Table 1 Details the static variables used to define the rearfoot, ankle, first ray, forefoot and hallux deformities investigated, the foot kinematic variables used to compare feet with and without the deformities, and the foot kinematic variables used in the assessment of any correlation between the degree of deformity and degree of compensatory foot motion
