Speech Therapy as Treatment for Supragastric Belching.

The purpose of this study was to describe a newly developed speech therapy program as an innovating therapeutic approach and to assess the results of this intervention in patients with supragastric belching. This is a retrospective analysis of prospectively gathered data from 73 patients with supragastric belching who were treated with speech therapy between 2007 and 2017. Of these, 48 were included for evaluation of therapy. Thirty patients had supragastric belching proven by 24-h impedance measurements. Eighteen patients were diagnosed by an experienced speech language pathologist as having supragastric belching according to precise criteria. Speech therapy consists of explanation, creating awareness of esophageal air influx and exercises to discontinue the supragastric belching mechanism. Therapy effect was measured by comparing visual analogue scale (VAS) scores on belching and related symptoms. The median symptom duration at the start of therapy was 2 years. Supragastric belching symptoms decreased significantly with a total median VAS score of 406 (291-463) prior to treatment and a median VAS score of 125 (17-197) following treatment. Forty patients (83%) had a sufficient to major result with a median therapy duration of 3 months and ten sessions. Speech therapy was an effective treatment in the majority of patients with supragastric belching.

The inability to belch syndrome: A study using concurrent high-resolution manometry and impedance monitoring.

INTRODUCTION: Although inability to belch has previously been linked to dysfunction of the upper esophageal sphincter (UES), its underlying pathogenesis remains unclear. Our aim was to study mechanisms underlying inability to belch and the effect of UES botulinum toxin (botox) injections in these patients. METHODS: We prospectively enrolled consecutive patients with symptoms of inability to belch. Patients underwent stationary high-resolution impedance manometry (HRIM) with belch provocation and ambulatory 24-h pH-impedance monitoring before and 3 months after UES botox injection. RESULTS: Eight patients (four males, age 18-37 years) were included. Complete and normal UES relaxation occurred in response to deglutition in all patients. A median number of 33(15-64) gastroesophageal gas reflux episodes were observed. Despite the subsequent increase in esophageal pressure (from -4.0 [-7.7-4.2] to 8 [3.3-16.1] mmHg; p < 0.012), none of the gastroesophageal gas reflux events resulted in UES relaxation. Periods of continuous high impedance levels, indicating air entrapment (median air presence time 10.5% [0-43]), were observed during 24-h impedance monitoring. UES botox reduced UES basal pressure (from 95.7[41.2-154.0] to 29.2 [16.7-45.6] mmHg; p < 0.02) and restored belching capacity in all patients. As a result, esophageal air presence time decreased from 10.5% (0-43.4) to 0.7% (0.1-18.6; p < 0.02) and esophageal symptoms improved in all patients (VAS 6.0 [1.0-7.9] to 1.0 [0.0-2.5]; p < 0.012). CONCLUSION: The results of this study underpin the existence of a syndrome characterized by an inability to belch and support the hypothesis that ineffective UES relaxation, with subsequent esophageal air entrapment, may lead to esophageal symptoms.

The effect of visual feedback and training in auditory-perceptual judgment of voice quality.

The aim of the present investigation was to evaluate the effect of visual feedback on rating voice quality severity level and the reliability of voice quality judgment by inexperienced listeners. For this purpose two training programs were created, each lasting 2 hours. In total 37 undergraduate speech-language therapy students participated in the study and were divided into a visual plus auditory-perceptual feedback group (V + AF), an auditory-perceptual feedback group (AF), and a control group with no feedback (NF). All listeners completed two rating sessions judging overall severity labeled as grade (G), roughness (R), and breathiness (B). The judged voice samples contained the concatenation of continuous speech and sustained phonation. No significant rater reliability changes were found in the pre- and posttest between the three groups in every GRB-parameter (all p > 0.05). There was a training effect seen in the significant improvement of rater reliability for roughness within the NF and AF groups (all p < 0.05), and for breathiness within the V + AF group (p < 0.01). The rating of the severity level of roughness changed significantly after the training in the AF and V + AF groups (p < 0.01), and the breathiness severity level changed significantly after the training in the V + AF group (p < 0.01). The training of V + AF and AF may only minimally influence the reliability in the judgment of voice quality but showed significant influence on rating the severity level of GRB parameters. Therefore, the use of both visual and auditory anchors while rating as well as longer training sessions may be required to draw a firm conclusion.
