Figure 8From: A protocol for classifying normal- and flat-arched foot posture for research studies using clinical and radiographic measurements Screening protocol for normal- and flat-arched foot posture. Flow chart shows how the foot posture screening protocol can be applied to future studies recruiting participants with normal- and flat-arched foot posture. CIA – calcaneal inclination angle, C1MA – calcaneal-first metatarsal angle, TNCA – talo-navicular coverage angle, T2MA – talus-second metatarsal angle.Back to article page
