Which statement is true regarding the navicular drop test interpretation?

• A. Small navicular drop indicates increased pronation
• B. Large navicular drop indicates decreased pronation
• C. Large navicular drop indicates increased pronation
• D. Navicular drop is not related to pronation

Answer: (C)

The navicular drop test is measuring how much the navicular bone lowers when the foot bears weight, which reflects how much the arch collaps during pronation. When the arch collapses more, the navicular moves downward by a larger amount. That greater drop corresponds to increased pronation. So, a large navicular drop indicates increased pronation. Conversely, a small drop suggests less pronation, and saying there's no relation to pronation isn’t accurate because the test is specifically about how much the arch collapses with weight bearing. Keep in mind this is one factor in a broader assessment of foot mechanics and function.
