What muscles cause pronation?

The main muscles that enable the pronation of the upper body are Pronator teres, pronator anterior, and brachioradialis. Supination is mainly facilitated by the supinator and biceps muscles. An upper extremity injury can damage any nerve or muscle involved in pronation and supination.
