Abstract
The purpose of this study was to establish validity for both musuloskeletal testing and motion analysis compared to ultrasound measures of tibial torsion. Twelve subjects between 18-30 years of age participated in the study. Each subject underwent 3 measures of tibial torsion: ultrasound, a musculoskeletal measure and motion analysis. There were no significant differences in the measure of tibial torsion generated by the ultrasound compared to musculoskeletal test (p values, right = 0.593, left = 0.388) neither were there difference between ultrasound and the motion analysis measures (p values, right = 0.541, left = 0.583). All three methods of tibial torsion measurement demonstrated good to excellent reliability across trials. These results indicate musculoskeletal testing and motion analysis provide a valid measure of tibial torsion in an adult population and should be considered when providing surgical recommendations.
