“…조음과 운율 측면은 말 하위체계 중 파킨슨병으로 인한 결함이 가장 두드러지는 것으로 보고된다 (Freed, 2012). 조음에서는 조음 기관의 운동 범위제한으로 상대적으로 빠르게 조음되면서 말 뭉침 이 관찰되기도 한다 (Freed, 2012;Kim, Yoon, & Lee, 2015;Ludlow, Bassich, McNeil, Rosenbek, & Aronson, 1984). 또한 파킨슨병 환자 의 경우는 정상 노화와는 구별되는 말명료도를 보였다 (Shim, Park, & Ko, 2012).…”

This study used a self-evaluation questionnaire survey on speech characteristics with patients with Parkinson's disease, and investigated the correlation between the survey's self-reported results and clinicians' speech evaluations. Methods: Forty patients with Parkinson's disease were divided into an mild group and a moderate/severe group according to limb hypokinesia severity. Then, speech tasks of maximum phonation time, diadochokinesia, and paragraph reading were conducted, and the results were quantified using Computerized Speech Lab. In the self-report questionnaire, respondents were asked about the subjective difficulty they encountered during the stages of respiration, phonation, articulation, and prosody based on a 5-point Likert scale. Results: First, shimmer, noise to harmonic ratio, and amplitude tremor intensity index in the maximum phonation time task, and the total repeat frequency of /pu/ and /putuku/, and /putuku/DDKsdp in the diadochokinesia task were significantly higher in the moderate/severe group; the total repeat frequency of /tu/ and /ku/ was significantly lower in the moderate/severe group; and the two groups showed no significant difference in the reading task. Second, the moderate/severe group complained of more difficulty in the self-reporting questionnaire. Third, speech evaluation measures and the questionnaire showed a correlation between voice-related diverse complaints and correct articulation and the speech evaluation measures in the mild group, while voice intensity or speech rate were correlated with speech evaluation measures in the moderate/severe group. Conclusion: Speech difficulty indicators in patient groups may differ with Parkinson's disease severity. This implies that self-recognition regarding speech characteristics should be considered in the intervention plan and prognosis establishment.

Purpose: Writing performance can be improved in patients with Parkinson’s disease (PD) by providing the visual cues. This study aimed to investigate the changes in pen pressure, letter size, and writing speed as per levels of visual cues.Methods: Sixty-three participants (38 PD patients and 25 normal adults) performed tasks, including sentence writing along visual cue levels using a tablet personal computer, digital pen, and software that could measure the pen pressure, stroke length, and duration.Results: First, the PD group’s pen pressure and letter size were improved when the visual cue was provided. Second, the effect of visual cues was shown more in the performance of ‘writing within square blanks’ than in the performance of ‘copying’ and ‘writing between parallel lines’. Especially, there were no significant differences between the groups in terms of the letter size in ‘writing within square blanks’.Conclusion: Despite movement disorders in PD patients, our findings suggest that pen pressure and letter size can be improved when the patients are provided visual cues. Our results indicate that providing visual cues hierarchically and objectively confirms changes in writing performance.

The purpose of this study was to investigate the speech characteristics and speech therapy of Parkinson disease (PD). This study selected 28 papers published in Korea from 1998 to 2018 after searching the terms 'Parkinson voice' and 'Parkinson speech therapy.' Literature review had been conducted in the two aspects of speech characteristics and speech therapy. The speech characteristics were divided into respiration, phonation, articulation, prosody, vowel production, and voice questionnaire. Speech therapy was divided into Lee Sliverman voice treatment (LSVT) and other voice therapy. PD patients did not differ in respiration function compared to normal elderly people, but their speech and articulation function were poorer. There was also a difference in the speech rate, frequency of pause, and accuracy of vowel production compared with normal elderly people. PD had a lower VHI score and their voice related quality of life was a little poorer. The LSVT was typically used in speech therapy for PD. The methods of speech therapy for PD have been shown to improve respiration and phonation. It is necessary to establish voice norms in PD patients and develop effective speech therapy in the following study.
