Research review (peer-reviewed)abstract
- Conclusion: Misdirected swallowing can be triggered by esophageal retention and hiatal incompetence. The results show that oral IQoro(R) screen (IQS) training improves misdirected swallowing, hoarseness, cough, esophageal retention, and globus symptoms in patients with hiatal hernia. Objectives: The present study investigated whether muscle training with an IQS influences symptoms of misdirected swallowing and esophageal retention in patients with hiatal hernia. Methods: A total of 28 adult patients with hiatal hernia suffering from misdirected swallowing and esophageal retention symptoms for more than 1 year before entry to the study were evaluated before and after training with an IQS. The patients had to fill out a questionnaire regarding symptoms of misdirected swallowing, hoarseness, cough, esophageal retention, and suprasternal globus, which were scored from 0-3, and a VAS on the ability to swallow food. The effect of IQS traction on diaphragmatic hiatus (DH) pressure was recorded in 12 patients with hiatal hernia using high resolution manometry (HRM). Results: Upon entry into the study, misdirected swallowing, globus sensation, and esophageal retention symptoms were present in all 28 patients, hoarseness in 79%, and cough in 86%. Significant improvement was found for all symptoms after oral IQS training (p < 0.001). Traction with an IQS resulted in a 65 mmHg increase in the mean HRM pressure of the DH.

- Conclusion All patients with dysphagia after stroke have impaired postural control. IQoro (R) screen (IQS) training gives a significant and lasting improvement of postural control running parallel with significant improvement of oropharyngeal motor dysfunction (OPMD). Objectives The present investigation aimed at studying the frequency of impaired postural control in patients with stroke-related dysphagia and if IQS training has any effect on impaired postural control in parallel with effect on OPMD. Method A prospective clinical study was carried out with 26 adult patients with stroke-related dysphagia. The training effect was compared between patients consecutively investigated at two different time periods, the first period with 15 patients included in the study more than half a year after stroke, the second period with 11 patients included within 1 month after stroke. Postural control tests and different oropharyngeal motor tests were performed before and after 3 months of oropharyngeal sensorimotor training with an IQS, and at a late follow-up (median 59 weeks after end of training). Result All patients had impaired postural control at baseline. Significant improvement in postural control and OPMD was observed after the completion of IQS training in both intervention groups. The improvements were still present at the late follow-up.

Effect of oral IQoro(R) and palatal plate training in post-stroke, four-quadrant facial dysfunction and dysphagia : A comparison study
- 2015
-
In: Acta Oto-Laryngologica. - : Informa UK Limited. - 0001-6489 .- 1651-2251. ; 135:9, s. 962-968
-
Journal article (peer-reviewed)abstract
- Conclusion: Training with either a palatal plate (PP) or an oral IQoro(R) screen (IQS) in patients with longstanding facial dysfunction and dysphagia after stroke can significantly improve facial activity (FA) in all four facial quadrants as well as swallowing capacity (SC). Improvements remained at late follow-up. The training modalities did not significantly differ in ameliorating facial dysfunction and dysphagia in these patients. However, IQS training has practical and economic advantages over PP training. Objectives: This study compared PP and oral IQS training in terms of (i) effect on four-quadrant facial dysfunction and dysphagia after a first-ever stroke, and (ii) whether the training effect persisted at late follow-up. Methods: Patients were included during two periods; 13 patients in 2005-2008 trained with a PP, while 18 patients in 2009-2012 trained with an IQS. Four-quadrant facial dysfunction was assessed with an FA test and swallowing dysfunction with a SC test: before and after a 3-month training period and at late follow-up. FA and SC significantly improved (p < 0.001) in both groups. FA test scores after training and at late follow-up did not differ significantly between the groups, irrespective of whether the interval between stroke incidence and the start of training was long or short.

Effects of motor and sensory stimulation in stroke patients with long-lasting dysphagia

Journal article (peer-reviewed)abstract
- Dysphagia is a common poststroke symptom with negative effects on recovery and rehabilitation. However, the orofacial regulation therapy, developed by Castillo Morales, comprising body regulation and orofacial regulation in combination with a palatal plate application has shown promising results in stroke patients. This therapy is based not only on muscle exercises but also on an improvement of the entire sensory-motor reflex arc involved in normal deglutition, and on the knowledge that the function of face and oropharynx at deglutition is closely interrelated with the entire body posture as well as with appropriate breathing. The treatment concept is relatively unknown to caregivers, partly due to lack of scientific evaluation of treatment results. The present investigation aimed to assess the effect of motor and sensory stimulation in stroke patients with dysphagia persisting for more than six months. Seven patients were evaluated with respect to orofacial and pharyngeal motility and sensory function before and two weeks after a five-week treatment period. The evaluation comprised a swallowing capacity test, a meal observation test, clinical examination of oral motor and sensory function, a velopharyngeal closure test, and videofluoroscopy. In addition, the symptoms were scored by the patients. An overall single-blind estimation showed objective and self-assessed swallowing improvement in all seven patients. Kappa coefficients are calculated on all reliability data, both inter- and intrarater reliabilities. Sensory and motor stimulation seems to be a promising therapy in stroke patients with long-lasting and persistent oropharyngeal dysphagia.

Esophageal dysphagia and reflux symptoms before and after oral IQoro(R) training
- 2015

Journal article (peer-reviewed)abstract
- AIM: To examine whether muscle training with an oral IQoro(R) screen (IQS) improves esophageal dysphagia and reflux symptoms. METHODS: A total of 43 adult patients (21 women and 22 men) were consecutively referred to a swallowing center for the treatment and investigation of long-lasting nonstenotic esophageal dysphagia. Hiatal hernia was confirmed by radiologic examination in 21 patients before enrollment in the study (group A; median age 52 years, range: 19-85 years). No hiatal hernia was detected by radiologic examination in the remaining 22 patients (group B; median age 57 years, range: 22-85 years). Before and after training with an oral IQS for 6-8 mo, the patients were evaluated using a symptom questionnaire (esophageal dysphagia and acid chest symptoms; score 0-3), visual analogue scale (ability to swallow food: score 0-100), lip force test (>= 15 N), velopharyngeal closure test (>= 10 s), orofacial motor tests, and an oral sensory test. Another twelve patients (median age 53 years, range: 22-68 years) with hiatal hernia were evaluated using oral IQS traction maneuvers with pressure recordings of the upper esophageal sphincter and hiatus canal as assessed by high-resolution manometry. RESULTS: Esophageal dysphagia was present in all 43 patients at entry, and 98% of patients showed improvement after IQS training [mean score (range): 2.5 (1-3) vs 0.9 (0-2), P < 0.001]. Symptoms of reflux were reported before training in 86% of the patients who showed improvement at follow-up [1.7 (0-3) vs 0.5 (0-2), P < 0.001). The visual analogue scale scores were classified as pathologic in all 43 patients, and 100% showed improvement after IQS training [71 (30-100) vs 22 (0-50), P < 0.001]. No significant difference in symptom frequency was found between groups A and B before or after IQS training. The lip force test [31 N (12-80 N) vs 54 N (27-116), P < 0.001] and velopharyngeal closure test values [28 s (5-74 s) vs 34 s (13-80 s), P < 0.001] were significantly higher after IQS training. The oral IQS traction results showed an increase in mean pressure in the diaphragmatic hiatus region from 0 mmHg at rest (range: 0-0 mmHG) to 65 mmHg (range: 20-100 mmHg). CONCLUSION: Oral IQS training can relieve/improve esophageal dysphagia and reflux symptoms in adults, likely due to improved hiatal competence.
