  1. X: dorsiflexion-plantarflexion/medio-lateral; Y: pronation-supination/anterior-posterior; Z: abduction-adduction/cranio-caudal; Scenario 1: Intact; Scenario 2: section of ATFL; Scenario 3: section of ATFL and CFL; Scenario 4: section of ATFL, CFL and PTFL; %: indicates the percentage increase/decrease of motion relative to Scenario 1 for the first 3 comparisons, relative to Scenario 2 in the 4th and 5th and relative to Scenario 3 in the last comparison.
