Efficacy of behavioral treatment for oropharyngeal dysphagia

In this critique of research in behavioral treatment of dysphagia, three types of investigations are briefly reviewed: general management guides, specific behavioral treatments applied to single patients or a few patients, and dysphagia programs applied to large numbers of patients. Efficacy of treatment has been demonstrated in some of the single-case or small-group studies where specific techniques have been utilized. Unfortunately, efficacy has not been demonstrated in any of the studies where large groups of patients have been enrolled in dysphagia programs. Some of the critical factors that have been lacking in many of these studies are discussed and the need to include functional outcome measures in efficacy studies is emphasized.
