Definition
Medial rotation is defined as the internal rotation of the limb towards the midline. For instance, the medial rotation at the hip joint can be brought about by internally rotating a fully extended lower limb, such that the big toe points inwards. The rotational movement occurs along the long axis of the lower limb. Similarly, when the arms are placed on the side of the chest and elbows flexed (as if holding a tray), then medial rotation at the shoulder joint can be brought about by bringing the forearm and hand inwards. The rotation movement occurs along the long axis of the humerus.
