Relationship between motor function of articulation organs and speech intelligibility in poststroke dysarthria
Objective To investigate the relationship between motor function of articulation organs and speech intelligibility(SI)in patients with dysarthria after stroke.Methods A total of 67 patients with dysarthria after stroke in Beijing Bo'ai Hospital from November,2020 to October,2023 were collected.They were assessed with SI test and Frenchay Dysarthria Assessment(FDA).The patients were divided into low SI group(SI≤65%)and high SI group(SI>65%).Results All the sub-scores of FDA were lower in the high SI group than in the low SI group(Z>1.543,P<0.05),except that of the jaw;and the SI was negatively pairwise correlated with FDA sub-scores(r<-0.343,P<0.001),espe-cially with the lip,tongue and laryngeal(r<-0.6).Conclusion The motor function of articulation organs may be related to SI in patients with dysarthria after stroke,espe-cially the lip,tongue and laryngeal.
