| dc.description.abstract | Parkinson’s disease (PD) is characterized by a combination of four primary symptoms: resting tremor, bradykinesia, rigidity, and postural instability, often accompanied by weakened laryngeal muscles. As a result, most patients experience difficulties with speech, voice, and swallowing, negatively impacting their quality of life. While the effectiveness of the Phonation Resistance Training Exercise (PhoRTE) voice therapy technique has been demonstrated in treating presbyphonia, research on its application to neurodegenerative diseases remains limited. Therefore, this study aims to apply the PhoRTE voice therapy technique to PD patients to investigate its effects not only on speech and voice but also on swallowing function and quality of life. A total of 19 patients with PD participated in the study, comprising 10 patients in the treatment group (5 males, 5 females; age = 74.90 ± 8.73) and 9 patients in the control group (6 males, 3 females; age = 77.00 ± 10.38). There were no significant differences between the groups in terms of age, K-MMSE, ASHA NOMS swallowing level scale, or speech POT. Patients in the treatment group underwent PhoRTE therapy for four weeks, with evaluations conducted before and after the treatment. Patients in the control group completed pre- and post-evaluations over a four-week interval without receiving therapy. The evaluation metrics included measures related to speech, voice, swallowing mechanisms, and questionnaires. The application of the PhoRTE voice therapy technique yielded significant results. From a voice perspective, the treatment group demonstrated significant improvements in MPT, jitter (p < .01), shimmer, CPPs (vowel) (p < .05), and speech intensity (vowel) (p < .001). In contrast, the control group showed a significant increase in jitter and shimmer (p < .05), indicating a worsening. From a speech perspective, the treatment group showed significant improvements in AMR /kuh/ and VSA (p < .05). From a swallowing perspective, the treatment group showed significant improvement in GUSS(p < .05). In terms of swallowing-related quality of life, the control group exhibited a significant decline in the SWAL-QOL total score (p < .05). This study is significant in demonstrating the effectiveness of applying voice therapy techniques not only to voice but also to swallowing function, which shares anatomical structures with voice mechanisms. Additionally, it highlights the clinical importance of providing timely and appropriate treatment for patients with Parkinson's disease, a degenerative condition. 파킨슨병 (Parkinson’s disease, PD)는 주요 4가지 증상으로 resting tremor, bradykinesia, rigidity and postural instability의 조합을 보이며 인후두 근력 약화가 나타난다. 따라서 환자 대부분이 말, 음성 및 삼킴에 어려움을 보이며 삶의 질에도 부정적 영향을 미친다. Phonation Resistance Training Exercise (PhoRTE) 음성치료 기법으로 노인성 발성장애를 치료했을 때 그 효과성은 입증되었으나 이를 신경학적 퇴행성 질환에 적용한 연구는 미비한 실정이다. 때문에 본 연구는 PhoRTE 음성치료 기법을 PD 환자에게 적용하여 말, 음성 뿐만 아니라 삼킴 기능의 개선과 삶의 질 변화를 알아보고자 한다. 총 19명의 PD환자를 대상으로 치료군 10명(남: 5명, 여: 5명, 연령 = 74.90±8.73), 대조군 9명(남: 6명, 여: 3명, 연령 = 77.00±10.38)의 대상자로 연구를 진행하였다. 이들의 연령, K-MMSE, ASHA NOMS swallowing level scale, speech POT에 대해서는 그룹 간 유의한 차이가 없었다. 치료군에 속하는 환자들은 4주 간 PhoRTE 치료를 받았으며 치료 전・후로 평가를 진행하였다. 대조군에 속하는 환자들은 4주 간격으로 사전, 사후 평가 만을 진행하였다. 실시한 평가 지표는 말, 음성, 삼킴 기제, 설문지를 포함하여 수집하였다. PhoRTE음성치료 기법을 적용한 결과, 음성 측면에서 치료군의 경우 MPT, jitter(p<.01), shimmer, CPPs(vowel)(p<.05), speech intensity(vowel)(p<.001)에서 유의한 변화를 보였고, 대조군의 경우 jitter, shimmer에서 유의한 증가를 보였다.(p<.05) 말 측면에서는 AMR/kuh/, VSA에서 유의한 변화를 보였다(p<.05). 삼킴 측면에서 치료군의 경우 GUSS에서 유의미한 증가를 보였으며(p<.05) 삼킴 관련 설문지에서는 대조군이 SWAL-QOL 총점에서 유의미하게 감소되었다(p<.05). 본 연구는 음성 뿐만 아니라 이와 해부학적 구조를 공유하는 삼킴 기능에 대해 음성치료 기법을 적용하여 그 효과성을 검증하였고, 퇴행성 질환인 PD환자들이 적시에 적절한 치료를 받는 것이 임상적으로 도움이 됨을 입증한데 의의가 있다. | - |
