Abstract
Introduction: There are various approaches to managing dysphagia. IQoro Screen Training (IQST) is a new technique that has recently gained researchers' attention. This treatment uses an Oral IQoro Screen device, which stimulates sensory input and muscle strength. This systematic review aimed to investigate the effect of IQoro Screen Training on oropharyngeal functions related to swallowing.
Materials and Methods: A search was conducted in PubMed, Scopus, Embase, Web of Science, Cochrane Library, and ProQuest databases through November 2022, and was updated in June 2023. Full-text studies published in English and investigating the effects of IQoro Screen Training on oropharyngeal functions related to swallowing were included. Studies that scored above 50% in methodological quality based on the Joanna Briggs Institute (JBI) and Single- case experimental design (SCED) forms were included in the data extraction phase.
Results: Following the screening of 67 records based on the predefined inclusion and exclusion criteria, 14 articles were selected, and after critical appraisal, 6 articles were included for data extraction. Among these, three were quasi-experimental studies, and one employed an SCED. The main objectives of these studies included investigating the effects of IQST on digestive disorders and dysphagia caused by neuromuscular defects, as well as its effects on the swallowing mechanism in healthy individuals.
Conclusion: The results of these studies indicated that IQoro screen Training has therapeutic potential in the treatment of swallowing disorders. However, there is still insufficient evidence to support its use in clinical settings. Therefore, further studies are needed to investigate the mechanism of this method on the swallowing process and the various muscles involved in swallowing.
