Figure 2

Screening protocol for flat-arched foot posture. Flow chart shows how the foot posture screening protocol was derived from normative data. * Values derived from Scott and colleagues [7]. The rationale for using 2 SD standard deviations was to increase the likelihood of participants with flat-arched feet qualifying for inclusion via radiographic appraisal. CIA – calcaneal inclination angle, C1MA – calcaneal-first metatarsal angle, TNCA – talo-navicular coverage angle, T2MA – talus-second metatarsal angle.
