Effects of Body Posture on Voice Range Profile Performance in Untrained Vocally Healthy Individuals.

PMID 40985577WHAT IT FOUND
Sitting or standing does not change Voice Range Profile results in healthy untrained adults.
Clinicians can measure in either position without affecting reliability. Repeating the test immediately caused no training effect, so the order of postures does not bias the data.
Key findings
01There was no statistically significant effect of body posture (sitting vs. standing) on any Voice Range Profile measure, with effect sizes being very small or small.
02No training effect was observed between the first and second measurements, and reliability was sufficient for all parameters.

What it does not show
The study only included untrained, vocally healthy adults, so the results may not apply to singers, actors, or patients with voice disorders. The two measurements were done consecutively with a short interval, which might have allowed participants to recall their previous performance, though no statistical training effect was found. Laryngeal imaging was not used to confirm the structural health of the vocal folds, relying instead on self-report questionnaires for screening.
Declared interests
The authors declared no conflicts of interest. The study was approved by the Ethics Committee.
The easy way to misread this
Do not assume these results apply to patients with voice pathologies or trained voice users. The study specifically examined untrained, healthy individuals, and posture might still influence performance in those groups.
