| ABSTRACT |
Objectives
Patients with right hemisphere damage (RHD) often struggle to understand the tone of others during communication and have difficulties expressing their own intentions. This study aims to examine the intonation characteristics of sentence-final endings in patients with RHD.
Methods
The study included a total of 38 participants (13 patients with right hemisphere cerebral infarction and 25 healthy adults). The study employed a sentence reading task (pitch, intensity range, intonation patterns), a prosodic perception/ difficulty scale (prosodic perception/difficulty scores), and a sentence type selection task (perception rates of sentence types).
Results
The group with RHD exhibited lower pitch ranges for imperative and interrogative sentences, as well as lower intensity ranges for imperative sentences compared to the healthy control (HC) group. An ascending intonation pattern was observed in declarative and imperative sentences in the RHD group, which was not seen in the HC group, while a descending intonation pattern was noted in interrogative sentences. Additionally, the RHD group tended to underestimate their own prosodic difficulties. HC listeners experienced challenges in identifying the sentence type based on the speech of patients with RHD.
Conclusion
This study provides a multifaceted confirmation of the vulnerable prosodic characteristics of patients with RHD. It objectively highlights the potential limitations that these prosodic difficulties may impose on the social participation of individuals with RHD in daily life. |
