- Parkinson's disease

- JPRN-UMIN000036223
- Brief Summary
Fourteen patients were followed-up until 12FU. Changes in dB SPL from baseline to immediately after treatment were +6.6 dB, +4.2 dB, and 2.8 dB, and those from baseline until 12FU were +4.8 dB, +3.5 dB, and +2.5 dB, respectively.These changes were significant (p < 0.05) in both the baseline-to-post-treatment and baseline-to-12FU intervals.Intelligibility was significantly improved immediately after treatment, but not at 12FU, relative to baseline. https://doi.org/10.1155/2020/6585264

- Primary Outcome Measures
Name Time Method The assessments described below were conducted at the following times: 1) pretreatment (Baseline), 2) immediately after four weeks of treatment, and 3) at the end of 12 months of follow-up (12FU) after four weeks of treatment. 1) Vocal loudness A) Sustained phonation of /a/,B) Reading a passage: "The North Wind and the Sun" C) Delivering a monologue: This task used the Japanese folk tale "Momotaro".
- Secondary Outcome Measures
Name Time Method 2) Intelligibility Intelligibility was assessed based on the reading of a passage and the production of a monologue recorded in vocal loudness testing. The audio samples were arranged randomly and assessed at a constant SPL by three speech-language pathologists with at least five years of experience. The audio data were copied and reassessed to examine the reproducibility of the original assessments. Intelligibility was assessed using a standard Japanese test, as described by Itoh et al. Audio samples were assessed on a nine-level scale in 0.5-point increment, including "1. Completely intelligible," "2. Some unintelligible words," "3. Intelligible if the listener knows the topic," "4. Few intelligible words," and "5. Completely unintelligible." Intraclass correlation coefficients (ICCs) were calculated to determine the assessor with the highest reliability; this assessor's assessments of intelligibility were used as reference values.
