The Effects of the “SPEAK OUT! ®” and “LOUD Crowd®” Voice Programs for Parkinson Disease
Open accessAbstract
Individuals with Parkinson's disease (PD) experience difficulties in various motor functions due to decreased amplitude and sensory guidance.Speech production is a motoric behavior, and difficulties with oral communication are often seen in these patients.The communication problems are primarily due to decreased airflow from the lungs, incomplete vocal fold vibration, and an insufficient range of motion and coordination of the speech articulators.Current behavioral management methods for communication difficulties with PD typically address the reduced vocal intensity in "one-on-one" voice therapy sessions.The present study investigated the effects of a set of voice remediation programs for PD that includes individual and group therapy components, namely, the SPEAK OUT!® and LOUD Crowd® programs.Objective measurements of vocal intensity and perceptual measurements of the patients' ratings of the voice were recorded during the pre-and post-voice treatment phases.Statistically significant improvements were identified in both objective and perceptual measurements.

In the citing paper
“Sex was not included as a covariate as no sex-related differences have been reported for perception of fatigue (Said et al., 2020) or SPL in people with PD (Fox & Ramig, 1997; Levitt et al., 2015).”

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.
