Dysarthria and quality of life in patients with amyotrophic lateral sclerosis
ABSTRACT Purpose: to analyze the impact of dysarthria on the quality of life in patients with amyotrophic lateral sclerosis. Methods: the study consisted of 32 subjects, divided into two groups (control group and study group) who underwent an initial interview for background information, followed by an evaluation based on the Dysarthria Assessment Protocol and completion of quality of life questionnaire "Living with Dysarthria - (LwD)". Exploratory data analysis was collected through mean, median, SD, minimum and maximum measures. A comparison was performed between the studied groups and a correlation was carried out between scores. The significance level adopted was 5%. Results: according to the findings, all sub-items analyzed by the dysarthria assessment protocol were statically significant (p <0.001) when comparing the groups. Regarding quality of life, a moderate positive correlation (p = 0.0008; Spearman's coefficient = 0.75202) was observed between the total score of the two protocols used, indicating that the higher the degree of dysarthria, the worse the Quality of Life (QOL) of the subject, according to the parameters evaluated. Conclusion: dysarthria affects all speech parameters herein assessed, in varying degrees, negatively impacting communication and quality of life.
