Internal hip rotators

To test the group of muscles responsible for an internal hip rotation we must do a passive external hip rotation.

Test: The subject is lying on his back. The tested leg is flexed 90 degrees at the hip and at the knee. The coach stands on the side of the tested leg and brings the foot of the tested leg inwards (doing a passive external hip rotation) while keeping the upper leg perpendicular to the ground at all times.

Results: Normal extensibility of the internal hip rotators is 45 degrees of movement. Less than 45 degrees is hypo-extensibility and more than 50-60 degrees in hyper-extensibility.
