Ultrasonography Comparison of Peroneus Muscle Cross-sectional Area in Subjects With or Without Lateral Ankle Sprains

Abstract

The peroneus longus CSA is reduced in participants with LAS compared with that in participants without LAS. The intraexaminer reliability of the ultrasonography protocol was excellent when quantifying the peroneus brevis and the peroneus longus muscle tissues and acceptable when quantifying connective tissue.
