ASSESSMENT OF OROFACIAL DYSFUNCTION IN ADULTS WITH NEUROGENIC MOTOR SPEECH DISORDERS BY USING OROFACIAL PROFILE TEST

Overview

Currently, there is no suitable test battery to accept severe motor speech disorders and related dysphagia disorders and low cognitive levels. The aim of the research was to create and use a new diagnostic tool - Orofacial profile to examine the orofacial area in adult individuals with motor speech disorder who have imitation problems due to severe motor disorder and associated problems of dysphagia, aphasia, apraxia and others. This test was used in a research group of 24 adult probands aged 17-67 years with dg. motor speech disorders regardless of coexisting craniotrauma-based disorders who do not benefit from visual, acoustic and verbal keys during examination. The aim of the test was to evaluate differences in the Orofacial area between groups of probands with respect to the degree of dysphagia, dysarthria and the time elapsed since the injury. The test-retest method of the Pair t-test was used to evaluate the reliability of the test. For evaluation of validity, parts of the Orofacial and standardized Dysarthric profile were measured using Pearson correlation coefficient. To verify hypotheses, the Kolmogorov-Smirnov test was used to determine normality of the sample. Furthermore, the parametric Independent Samples t-Test and the U-test of Mann and Whithney were used. In determining the degree of difference with respect to clinically focused research, not only statistical signifikance but also effect size was determined using the Cohen coefficient d . As a result, it was found that between groups of probands with different degrees of dysphagia a statistically significant differenceand also great effect size was found. statistically significant difference and also great effect size in all orofacial areas. There was also a statistically significant difference between groups of probands with varying degrees of dysarthria with a large effect size in the orofacial area of ​​the Body, Jaw, Face, Lips, Breathing and Oral Phase of Swallowing. There was no statistically significant difference between the groups of probands examined within three years after the injury and more than three years after the injury. We can speak about medium effect size only in the area of ​​Breathing. New diagnostic tool The orofacial profile showed high reliability and validity based on statistical methods used.
