navicular drop test

navicular drop test

A clinical instrument used to evaluate the function of the medial longitudinal arch of the foot, which is of interest in patients with overuse injuries. The dynamic navicular drop is influenced by foot length and gender, resulting in conflicting results regarding differences in navicular drop between healthy and injured participants.

navicular drop test

A test used to quantify pronation of the foot. While the patient's foot is in a non–weight-bearing position, the examiner places a mark over the navicular tuberosity. Next, the foot is placed on the floor, again in a non–weight-bearing position, and a mark is made on a 3 × 5 index card to measure the distance between the floor and the navicular tubercle. The measure is repeated when the patient bears weight on the foot and the distance between the two marks is recorded. Inferior displacement of greater than 10 mm while bearing weight is considered hyperpronation of the foot.
