A randomized study comparing the Shaker exercise with traditional therapy: a preliminary study.

Seven institutions participated in this small clinical trial that included 19 patients who exhibited oropharyngeal dysphagia on videofluorography (VFG) involving the upper esophageal sphincter (UES) and who had a 3-month history of aspiration. All patients were randomized to either traditional swallowing therapy or the Shaker exercise for 6 weeks. Each patient received a modified barium swallow pre- and post-therapy, including two swallows each of 3 ml and 5 ml liquid barium and 3 ml barium pudding. Each videofluorographic study was sent to a central laboratory and digitized in order to measure hyoid and larynx movement as well as UES opening. Fourteen patients received both pre-and post-therapy VFG studies. There was significantly less aspiration post-therapy in patients in the Shaker group. Residue in the various oral and pharyngeal locations did not differ between the groups. With traditional therapy, there were several significant increases from pre- to post-therapy, including superior laryngeal movement and superior hyoid movement on 3-ml pudding swallows and anterior laryngeal movement on 3-ml liquid boluses, indicating significant improvement in swallowing physiology. After both types of therapy there is a significant increase in UES opening width on 3-ml paste swallows.

What information do clinicians use in recommending oral versus nonoral feeding in oropharyngeal dysphagic patients?

There is little evidence regarding the type(s) of information clinicians use to make the recommendation for oral or nonoral feeding in patients with oropharyngeal dysphagia. This study represents a first step toward identifying data used by clinicians to make this recommendation and how clinical experience may affect the recommendation. Thirteen variables were considered critical in making the oral vs. nonoral decision by the 23 clinicians working in dysphagia. These variables were then used by the clinicians to independently recommend oral vs. nonoral feeding or partial oral with nonoral feeding for the 20 anonymous patients whose modified barium swallows were sent on a videotape to each clinician. Clinicians also received data on the 13 variables for each patient. Results of clinician agreement on the recommendation of full oral and nonoral only were quite high, as measured by Kappa statistics. In an analysis of which of the 13 criteria clinicians used in making their recommendations, amount of aspiration was the criterion with the highest frequency. Recommendations for use of postures and maneuvers and the effect of clinician experience on these choices were also analyzed.
