Abstract

Individuals with Parkinson's disease (PD) demonstrate low vocal intensity (hypophonia) which results in reduced speech intelligibility. We examined the effects of three cues to increase loudness on respiratory support in individuals with PD. Kinematic data from the rib cage and abdomen were collected using respiratory plethysmography while participants read a short passage. Individuals with PD and normal age‐ and sex‐matched controls (OC) increased sound pressure level (SPL) to a similar extent. As compared to OC, individuals with PD used larger rib cage volume excursions in all conditions. Further, they did not slow their rate of speech in noise as OC speakers did. Respiratory strategies used to support increased loudness varied with the cue, but the two groups did not differ in the strategies used. When asked to target a specific loudness, both groups used more abdominal effort than at comfortable loudness. Speaking in background noise resulted in the largest increase in SPL with the most efficient respiratory patterns, suggesting that natural or implicit cues may be best when treating hypophonia in individuals with PD. Data demonstrate the possibility that both vocal loudness and speech rate are impacted by cognitive mechanisms (attention or self‐perception) in individuals with PD. © 2007 Movement Disorder Society

  • Sadagopan and Huber (2007) reported that the respiratory patterns of 14 individuals with Parkinson's disease approached the patterns of neurotypical age- and sex-matched controls when an external cue, multitalker background noise, was used to elicit increased vocal intensity, as compared to the respiratory patterns observed in response to an internal cue.

    “Sadagopan and Huber (2007) reported that the respiratory patterns of 14 individuals with PD approached the patterns of neurotypical age- and sex-matched controls when an external cue, multitalker background noise, was used to elicit increased vocal intensity, as compared to the respiratory patterns observed in response to an internal cue (e.g., speak at twice your comfortable loudness).”

  • The present respiratory kinematic data are in accordance with prior studies reporting aberrations in speech breathing for persons with PD.

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.
