目的:验证水抵抗疗法(WRT)对帕金森病(PD)患者的声音质量的影响。
方法:这是一项回顾性分析研究。然后,样本来自一个由10名年龄在50至90岁之间的男性诊断为PD的数据库。参与者用共振管接受了WRT;然后,他们被引导执行以下语音任务:舒适的音调和响度,高音,低间距,上升和下降的glissandos,句子说话。此外,管深2cm~9cm。最后,WRT每周实施两次,共八次会议,每次持续45分钟。在每次治疗之前和之后对参与者进行评估。因此,数据通过光谱分析进行评估,声带强度,倒谱峰突出度平滑,阿尔法比率,L1-L0,振荡频率,和整体程度的听觉感知评估,粗糙度,呼吸,和不稳定性。应用单向重复测量方差分析和Friedman检验(P<0.05)。此外,使用Holm-Sidak和Tukey测试作为postthoc测试。
结果:在第六届会议之后,光谱分析显示,中频的描边颜色强度变暗,而在第八届会议之后可以观察到更好的结果。关于声音强度,从第三届会议开始,可以观察到这种改善。此外,L1-L0遵循相同的结果。整体程度的听觉-知觉评估只有在第二次之后才显示出最好的结果,第三,和第四届会议;然而,在第八届会议之后,不稳定性增加。
结论:WRT允许从第三届会议获得更好的结果,在第六届会议上有一些改进。然而,第八届会议后,不稳定性加剧;因此,重要的是检查语音任务和会话编号,以避免语音系统过载。
OBJECTIVE: Verify session-by-session effects of the water resistance therapy (WRT) on the vocal quality of individuals with Parkinson\'s disease (PD).
METHODS: This is a retrospective analytical study. Then, the samples were acquired from a database composed of 10 men aged between 50 and 90 years old diagnosed with PD. The participants underwent WRT with a resonance tube; then, they were guided to perform the following phonatory tasks: comfortable pitch and loudness, high pitch, low pitch, ascending and descending glissandos, and sentence uttering. Furthermore, tube depth ranged from 2 cm to 9 cm. Finally, WRT was implemented twice per week, totaling eight sessions, each lasting 45 minutes. Participants were assessed before and after each therapy session. Hence, the data were assessed with spectrographic analysis, vocal intensity, cepstral peak prominence-smoothed, alpha ratio, L1-L0, oscillatory frequency, and auditory-perceptual assessment of overall degree, roughness, breathiness, and instability. One-way repeated measures analysis of variance and Friedman tests were applied (P < 0.05). Furthermore, Holm-Sidak and Tukey tests were used as posthoc tests.
RESULTS: After the sixth session, the spectrographic analysis revealed that the tracing color intensity of medium frequencies darkened, whereas a better result could be observed after the eighth session. Regarding vocal intensity, the improvement could be observed from the third session. Additionally, L1-L0 followed the same results. The overall degree auditory-perceptual assessment revealed the best results only after the second, third, and fourth sessions; however, after the eighth session, the instability increased.
CONCLUSIONS: WRT allowed better results from the third session, with some improvements in the sixth session. However, the instability increased after the eighth session; thus, it is important to review the phonatory tasks and session numbers to avoid an overload in the phonatory system.
