From: A protocol for classifying normal- and flat-arched foot posture for research studies using clinical and radiographic measurements

  Radiographic measures Clinical measurements

  1. AI – arch index, NNHt – normalised navicular height truncated, CIA – calcaneal inclination angle, C1MA – calcaneal first metatarsal angle, TNCA – talo-navicular coverage angle, T2MA – talus-second metatarsal angle.
  2. *Significant at p < 0.05, **Significant at p < 0.01
