Abstract
Background: Stroke is the second leading cause of death worldwide and the third leading cause of disability. It is the most common cause of aphasia, which can be associated with dysarthria and dyspraxia in some cases. The aim of this study was to compare the dysarthria of individuals with stroke before and after treatment.
Methods: The study design and implementation method were quasi-experimental. Fifteen adult patients with a mean age of 50 years, all diagnosed with dysarthria, were included in this study and evaluated using the Radboud Dysarthria Assessment (RDA). After coordinating with speech-language pathologists, neurologists, and other relevant specialists at the University of Social Welfare and Rehabilitation Sciences (USWR), individuals who had experienced a stroke at least 1 year prior and met the inclusion criteria were selected. The rate of improvement in their dysarthria was compared between pre- and post-treatment. The aim is to evaluate the effectiveness of speech therapy in improving dysarthria symptoms in stroke patients through pre- and post-treatment comparison. All patients had damage to the right hemisphere of the brain, and the ratio of women to men was 7 to 8. The average time from the onset of the subjects' illness was 6.4 months.
Results: The non-parametric Wilcoxon test was used to assess the status of the investigated variables before and after treatment. The results indicated a statistically significant difference between the conditions before and after treatment for all variables (p < 0.02).
Conclusion: Based on the purpose of the research, comparing the dysarthria of individuals with stroke before and after treatment, along with appropriate and regular therapeutic exercises during six months of rehabilitation, the final evaluation of the research variables concluded that a noticeable difference exists in the condition of dysarthria before and after treatment. In other words, the results show a statistically significant difference between the conditions before and after treatment for all the variables.
