The purpose of this study is to examine the acoustic characteristics of Parkinsonian speech, with respect to different utterance conditions, by employing acoustic/auditory-perceptual analysis. The subjects of the study were 15 patients (M=7, F=8) with Parkinson's disease who were asked to read out s...

파킨슨병이란? | 파킨슨병(Parkinson disease, PD)은 중뇌 흑질의 도파민 신경세포의 결함으로 나타나는 신경학적 퇴행성 질환 중 하나이며, 과소운동형 마비말장애(hypokinetic dysarthria)로 언급된다. 파킨슨병은 보통 60세 이후에 발생하지만, 10% 정도는 젊은 나이에 진단받기도 한다. | |
파킨슨병 환자들의 말 명료도 저하를 극복하기 위해 적용되는 접근법은? | 파킨슨병 환자들의 주요 문제인 말 명료도 문제를 보완하기 위해 LSVT(lee silverman voice treatment) 등의 중재 접근법이 치료에 적용되어 왔으며, 비교적 최근에는 명료발화(clear speech) 를 통한 접근이 제안되고 있다(Tjaden, 2008). 명료발화는 다양한 지시방법으로 유도할 수 있는데, 다양한 말 산출 조건에서 파킨슨병 환자의 명료발화를 유도한 결과, “청각장애 환자와 대화 하는 것처럼 말하세요”로 발화를 유도하였을 때, 마찰음 길이 (fricative durations)와 기본주파수와 음압수준 등의 초분절적 조절이 가장 용이하였다고 하였다(Lam & Tjaden, 2016). | |
파킨슨병의 주요 말 문제는? | 파킨슨병의 주요 말 문제는 기식 발성(breathy phonation), 목쉰 음성(hoarseness), 음성 강도 감소, 부정확한 조음, 운율 문제로 인해 말 명료도에 영향을 미치고, 이는 환자들의 의사소통적, 사회적, 경제적, 심리적 문제를 야기할 수 있다. Logemann et al. |
