Acute Effect of Active Tibial Rotation Exercise on Tibial Torsion Angle, Ankle Range of Motion, and Neuromuscular Control

PURPOSE: This study aimed to analyze the acute effect of active tibial rotation exercise on tibial torsion angle, ankle range of motion, and neuromuscular control.METHODS: This study was based on AB/BA Cross-over design, and participants were divided into two conditions (core-tex tibial and manual tibial rotation exercises). Before and after the exercise intervention, tibial torsion angle, non-weight bearing ankle range of motion, weight-bearing ankle range of motion and dynamic balance test, and Shark skill test were conducted.RESULTS: An interaction effect was found in the left non-weight-bearing ankle range of motion and the right posterolateral (PL) of theY Balance Test. In addition, there were significant differences between periods in left tibial torsion angle, non-weight-bearing anklerange of motion, bilateral weight-bearing ankle range of motion, bilateral AN, bilateral posteromedial, right PL, bilateral compositescore, and bilateral Shark skill test.CONCLUSIONS: Tibial rotation exercise is considered valuable as sports injury prevention training due to its effectiveness for lowerextremities functionally and structurally regardless of tibial rotation exercise type.
