Treatment efficacy for adults with oropharyngeal dysphagia.

Over the last 10 years, the literature in the area of oropharyngeal dysphagia has focused on treatment techniques for specific medical conditions and the documentation of treatment efficacy. Increasingly, there has been multidisciplinary involvement in the study of swallowing physiology and dysphagia. Investigators have used a wide range of technologies in quantifying changes in swallowing physiology as a result of imposed therapeutic adjustments and maneuvers. Group studies and single case design investigations have attempted to address the question of treatment efficacy. This article addresses the status of clinical treatment and the future needs for research.
