internal rotation

Medial rotation The act of turning about an axis passing through the center of the leg, which occurs with closed chain pronation; the talus acts as an extension of the leg in the frontal and transverse planes. Cf External rotation.

in·ter·nal ro·ta·tion

(in-tĕr'năl rō-tā'shŭn)
Movement of a joint, around its long axis, toward the midline of the body.
Synonym(s): medial rotation.

internal rotation

movement at a joint which rotates the limb, or a part of a limb, inwards, e.g. rotation of the whole arm inwards at the shoulder or rotation of the forearm at the elbow, to bring the palm facing backwards; equivalent movement possible to some extent at the hip but not at the knee. Opposite of external rotation. See Figure 1.
