Extensor indicis proprius (EIP) is examined and tested with extensor digitorum communis (EDC) and extensor digiti minimi. EIP runs parallel with the tendon of the EDC to the index finger on the ulnar/lateral side and inserts into the extensor expansion of the index finger with EDC. Refer to extensor digitorum communis for examination This muscle also may be called the extensor indicis. Guide the patient to pronate. Guide the patient to extend and flex the index finger while keeping the other 3 fingers and thumb flexed. Observe that as the first finger extends, the tendon of the extensor digitorum. G.
