Significance of Medial rotation
Medial rotation, as described in health sciences, encompasses various movements. It is a critical component of hand function, enabling gripping and manipulation. Clinically, medial rotation is assessed in the humerus, with a normal range of motion of 90 degrees. This movement also applies to the knee joint and is vital in clinical examinations. Furthermore, medial rotation is a type of exercise used to strengthen hip muscles. It is also associated with the humerus and is produced by specific muscles, including the popliteus, semitendinosus, and others.

The concept of Medial rotation in scientific sources
Medial rotation involves movements in the humerus, knee, and hip. It is facilitated by muscles like popliteus and semitendinosus, and is essential for shoulder and hand function. This movement is used in clinical examinations and is incorporated in exercise programs.

(1) Medial rotation is a type of movement that occurs around the long axis of the humerus, as described in the context of shoulder movements.[1] (2) Medial rotation is produced by popliteus, semitendinosus and possibly semimembranosus, gracilis and sartorius, according to the provided text.[2] (3) The examiner rotates the humerus and notes how far behind the patient's back the forearm can be rotated, and the normal range of motion is 90 degrees, as stated in the text.[3] (4) A movement where the thumb swings across the palm, which, when combined with flexion, causes opposition, crucial for the hand's gripping and manipulation capabilities.[4] (5) This is a type of exercise that is assisted and practiced to help strengthen the hip muscles, and it is included in both the post-operative and home exercise programs for the patient.[5]
