Trial Outcomes & Findings for Predicting Ankle Injury Through Clinical Functional Measures in Adolescent Athletes (NCT NCT01658709)

NCT ID: NCT01658709

Last Updated: 2025-07-23

Results Overview

The clinical measure of dynamic postural control is represented as a reaching distance normalized to leg length. This is calculated by taking the average liner reaching distance (cm) of the test trials and dividing by the participant's leg length (anterior superior iliac spine to the inferior pole of the medial malleolus of the tibia), also in cm. The resulting ratio is multiplied by 100 and the measure reported as "% of leg length". This value was established in the literature as the standard outcome for reporting Star Excursion Balance Test data.
