OBJECTIVE: To validate a novel device termed the equinometer, which is designed to accurately measure ankle dorsiflexion. DESIGN: Test retest reliability analysis using serial measurements of dorsiflexion endpoint in a group of normal individuals. SETTING: Motion analysis laboratory. PARTICIPANTS: Ten healthy individuals. PRIMARY OUTCOME MEASURE: The mean and standard deviation of the absolute difference in dorsiflexion endpoint for the group. RESULTS: The mean absolute change in dorsiflexion endpoint for the group was 0.45 degrees with a standard deviation of 0.43 degrees. CONCLUSIONS: With the use of the device described, the mean change in dorsiflexion endpoint was well within acceptable clinical limits. The reliability of measurements obtained with the equinometer exceeds that which has been published with other techniques and devices.
