Abstract

Vector coding (VC) is a nonlinear data analysis technique that provides a quantitative measure of coordination and coordination variability. The outcome measure derived from the VC technique is referred to as the coupling angle. Chang, Emmerik, and Hamill (Citation2008) whilst reporting these coupling angles introduced the terms ‘in-phase’, ‘anti-phase’, ‘proximal phase’ and ‘distal phase’. Although this approach provided a fresh outlook to the coordination pattern between rearfoot and forefoot, a later study (Needham, Naemi, & Chockalingam, Citation2015a) built on this approach to provide a novel technique that incorporated information on segment and phase dominance. This approach enabled us to offer further understanding of the coupling angle to contain in-phase or anti-phase coordination along with segmental dominancy within 45° coordination pattern bins.

Whilst Needham, Naemi, and Chockalingam (Citation2015b) looked at inter-segmental foot movement during level walking, one needs to understand how this movement and the coordination pattern changes whilst walking on an incline. We negotiate surfaces of varying incline during activities of daily living. An understanding of the inter-segmental movement and the coordination patterns will influence the way we design our functional footwear and foot orthotics.
