Dysphagia, or difficulty in swallowing, can cause food to enter the airway, resulting in coughing, choking, pulmonary problems, aspiration or inadequate nutrition and hydration with resultant weight loss, failure to thrive, pneumonia and death. It is most often due to complex neurological and/or structural impairments including head and neck trauma, cerebrovascular accident, neuromuscular degenerative diseases, head and neck cancer, dementias, and encephalopathies. For these reasons, it is important that only qualified professionals with specific training and experience in this disorder provide evaluation and treatment.

The speech-language pathologist performs clinical and instrumental assessments and analyzes and integrates the diagnostic information to determine candidacy for intervention as well as appropriate compensations and rehabilitative therapy techniques. The equipment that is used in the examination may be fixed, mobile or portable. Professional guidelines recommend that the service be provided in a team setting with a physician/NPP who provides supervision of the radiological examination and interpretation of medical conditions revealed in it.

Swallowing assessment and rehabilitation are highly specialized services. The professional rendering care must have education, experience and demonstrated competencies. Competencies include but are not limited to: identifying abnormal upper aerodigestive tract structure and function; conducting an oral, pharyngeal, laryngeal and respiratory function examination as it relates to the functional assessment of swallowing; recommending methods of oral intake and risk precautions; and developing a treatment plan employing appropriate compensations and therapy techniques.
