winging of the right<unk>  Winging of the left<unk>  The severity and appearance of the<unk>  varies by individuals as well as the muscles and/or nerves that were affected. Pain is not seen in every case. In a study of 13 individuals with facioscapulohumeral muscular dystrophy (FSHD), none of the individuals complained of pain. Fatigue, however, was a common characteristic and all had noted that there were limitations in their activities of daily life. In most cases of<unk> , damage to the serratus anterior muscle causes the deformation of the back. The serratus anterior muscle attaches to the medial anterior aspect of the<unk>  (i.e. it attaches on the side closest to the spine and runs along the side of the<unk>  that faces the ribcage) and normally anchors the<unk>  against the rib cage. When the serratus anterior contracts, upward rotation, abduction, and weak elevation of the<unk>  occurs, allowing the arm to be raised above the head. The long thoracic nerve innervates the serratus anterior; therefore, damage to or impingement of this nerve can result in weakening or paralysis of the muscle. If this occurs, the<unk>  may slip away from the rib cage, giving it the wing-like appearance on the upper back. This characteristic may particularly be seen when the affected person pushes against resistance. The person may also have limited ability to lift their arm above their head. In FSHD, the<unk>  is detected during contraction of the glenohumeral joint. In this movement, the glenohumeral joint atypically and concurrently abducts and the<unk>  internally rotates.
