Brief Summary

The aim of this study is to determine the normative values of navicular height and navicular drop in individuals over 65 years of age. The secondary aim is to investigate the effects of age, gender, and body mass index on these normative values.

Outcome Measures

Primary Outcomes (1)

  • Navicular Drop Test

    The navicular height and the amount of navicular drop will be made separately for each foot. The navicular prominence is found by palpation and marked with a marker pen when the individual is in a sitting position with the hips and knees flexed to 90 degrees and the subtalar joint in neutral position (the subtalar joint is palpated and the talus is in a neutral position). The height of the navicular protrusion from the ground is measured with a rigid ruler. Then, while the person stands on both feet equally, the height of the navicular protrusion from the ground is also measured with a ruler. The difference between the two measurements is noted as the amount of "navicular drop" (NDT).
