An interventional study of Cardiovascular Conditioning Protocol and Voice Production Exercises in Vocal Fatigue and Treatment, sponsored by East Tennessee State University. Completed at 1 site in United States. Open to female participants aged 21 Years to 60 Years. Per ClinicalTrials.gov, last updated 2023-11-18.
Sponsored by East Tennessee State University · Not applicable, Interventional, and Treatment
Teachers are a population at high risk for voice disorders given their occupational demands. In a teaching career, a common debilitating symptom among all vocal symptoms experienced is - vocal fatigue, impacting teachers' occupational performance and increasing health care costs. It is therefore essential to identify potential treatment options to alleviate the symptom of vocal fatigue. The purpose of this study is to utilize a body-system level cardiovascular training protocol in comparison to traditional voice production training to alleviate the symptoms of vocal fatigue.
77 studies on the registry are indexed under Voice Disorders; 17 are open to participants now.
This study's enrollment of 31 is below the median of 41 across 54 interventional studies indexed under Voice Disorders.

Changes in Physiologic Cost of Speaking
Physiologic Cost of Speaking is measured as the rate of oxygen consumption at steady state/ rate of speech (wpm) for each of the two reading tasks
Time frame: At baseline, at 4 weeks after treatment
Changes in Oxygen Uptake Kinetics
Oxygen Uptake Kinetics is measured as the pattern of oxygen use during each of the two reading tasks
Time frame: At baseline, at 4 weeks after treatment
Changes in Post Task Physiological Recovery
Post Task Physiological Recovery is measured as the time, seconds, to reach baseline of oxygen consumption post task (within 0.2ml/kg/min) following each of the reading tasks
Time frame: At baseline, at 4 weeks after treatment
Changes in Excess Post Exercise Consumption (EPOC)
EPOC is measured as the magnitude of recovery oxygen consumption, ml/kg/min for each of the reading tasks
Time frame: At baseline, at 4 weeks after treatment
Changes in Ratings of Perceived Exertion (RPE)
Borg Scale of Ratings of Perceived Exertion (RPE)- measures the self-report of vocal effort for each of the reading tasks
Time frame: At baseline, at 4 weeks after treatment
Changes in Vocal Fatigue Index (VFI)
Vocal Fatigue Index (VFI) is a retrospective scale that measures self-reported symptoms of vocal fatigue
Time frame: At baseline, at 4 weeks after treatment
Changes in Global Rating of Vocal Fatigue (VAS 100mm)
Global Rating of Vocal Fatigue (VAS 100mm) measures the ability to sustain voice with no fatigue at the end of a working day
Time frame: At baseline, at 4 weeks after treatment

Ran from Feb 2020 to primary completion in Mar 2023, 37 months.
Of 30 interventional studies with no phase under Voice Disorders, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 48. This study's 37 months is close to that.
