Efficacy and Acceptance of a Lombard-response Device for Hypophonia in Parkinson’s Disease
Open accessAbstract
OBJECTIVE: The purpose of this study was to examine the effectiveness, satisfaction, and acceptance of a low-cost Lombard-response (LR) device in a group of individuals with Parkinson's disease (IWPD) and their communication partners (CPs). METHOD: Sixteen IWPD and hypophonia and their CPs participated in the study. The IWPD wore a LR device that included a small MP3 player (Sony Walkman) and headphones playing a multi-talker noise audio file at 80 dB during lab-based speech tasks and during their daily conversational speech over a 2-week device trial period. Outcome measures included average conversational speech intensity and scores on a questionnaire related to speech impairment, communication effectiveness, and device satisfaction. RESULTS: Conversational speech intensity of the IWPD is increased by 7 to 10 dB with the LR device. Following a 2-week trial period, eight of the IWPD (50%) gave the LR device moderate-to-high satisfaction and effectiveness ratings and decided to purchase the device for long-term daily use. At the 4-month follow-up, none of the IWPDs were still using the LR device. Device rejection was related to discomfort (loudness), headaches, interference with cognition, and difficulty controlling device. CONCLUSION: Short-term acceptance and satisfaction with the LR device was moderate, but long-term acceptance, beyond 4 months, was absent. Future studies are required to determine if other types of low-cost LR devices can be developed that improve long-term efficacy and device acceptance in IWPD and hypophonia.

Neurologically intact and neurologically impaired individuals have been shown to significantly increase vocal intensity when speaking in the presence of background noise.
“Neurologically intact (Shrivastav et al., 2014; Whittico et al., 2020) and neurologically impaired (Adams et al., 2020; Richardson & Sussman, 2019; Shrivastav et al., 2014; Stathopoulos et al., 2014) individuals have been shown to significantly increase their vocal intensity when speaking in the presence of background noise.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
