What is the normal range of lateral tibial rotation measured during the Tibial Torsion Test in adults?

The normal range of lateral tibial rotation measured during the Tibial Torsion Test in adults is indeed between 12 and 18 degrees. This measurement is important in assessing the alignment of the tibia in relation to the distal femur and understanding the biomechanical function of the lower limb.

During the test, excessive lateral rotation or insufficient lateral rotation can indicate variations in tibial torsion, which may have implications for movement patterns, gait, and potential injury risk. A range of 12 to 18 degrees is considered reflective of typical adult anatomical variability without compromising functional movements. This standard serves as a baseline for identifying abnormal torsion, which can influence interventions or therapeutic approaches in physical therapy.
