Abstract
The navicular drop test was used as an indicator of foot pronation. It is defined as the distance between the original height of the navicular from the floor, with the foot on the floor in sitting in the subtalar neutral position, and the final weight-bearing position of the navicular in relaxed stance. This measurement is thought to represent the sagittal plane displacement of the navicular bone from a neutral position to a relaxed standing position. The purpose of this study was to test intra-rater reliability of a method for measuring the navicular drop. Fourteen healthy subjects, mean age 34.5±5.68 years, participated in the reliability study. Foot pronation was assessed using the navicular drop test. Measurements of the navicular drop were performed three times on each foot, one day apart and were averaged for statistical analysis. Statistical analysis was performed using SPSS (SPSS 10, for Windows). Intraclass correlation coefficients were 0.78 and 0.88 for the dominant and non- dominant leg respectively. The results demonstrated moderate to good intra-rater reliability for use of the navicular drop test for measuring foot pronation in clinical settings.
