The "baseball cap orthosis": a simple solution for dropped head syndrome.

Dropped head syndrome (DHS) is a well-recognized condition characterized by gradual sagging of the head. At the extreme, the condition may lead to a "chin on chest deformity" where the chin rests on the chest wall and the patient is unable to look straight ahead. Dropped head syndrome tends to develop in patients with severe weakness of the neck extensors. Various neuromuscular disorders and surgical procedures may compromise the stability of the cervical spine and lead to this disorder. The condition may severely compromise the patient's quality of life and result in significant disability. A simple device-the "baseball cap orthosis"-was developed to help patients maintain their head in the upright position. Two patients with DHS who were provided with the baseball cap orthosis are presented.
