If an inflamed appendix is in contact with the obturator internus, spasm of the muscle can be demonstrated by flexing and internally rotating the hip.

Additionally, with the hip flexed the gluteus medius and minimus internally rotate the thigh.

Lateral cricoarytenoid muscles adduct and internally rotate the arytenoid cartilages, which can result in adducted vocal folds.

The hips are adducted, rotated internally, and exhibit neutral extension.

With the hip extended, the gluteus medius and gluteus minimus internally rotate the thigh.

They are not utilized significantly during strict transverse extension (shoulder internally rotated) such as in rowing movements, which use the posterior fibers.

Likewise the medial knee can be stabilized in a fully flexed position and the leg internally rotated as the leg is extended.

This is also the name of a manoeuvre used to reduce anterior shoulder dislocations by externally rotating the shoulder, before adducting and internally rotating it.

These devices internally rotate the femoral head and abduct the leg(s) at 45 degrees.

In this movement, the glenohumeral joint atypically and concurrently abducts and the scapula internally rotates.
