Introduction:
In daily phoniatric practice, apart from laryngoscopy, another simple and useful method of examining the voice organ is perceptual voice assessment based on the GRBAS scale. An extension to this examination can be the Voice Handicap Index test (VHI).
Materials And Methods:
79 female teachers taking part in a 7-week-long rehabilitation course on voice emission techniques. Before and after the course the participants were subject to phoniatric examination including laryngovideostroboscopy, GRBAS scale assessment and determining the voice handicap index (VHI).
Results:
After the course, a substantial improvement has been observed in voice emission, perceptual assessment and the VHI test. It has been observed that there is a statistically significant correlation between GRBAS and VHI results and mean phonation time (MPT) measured before and after the course.
Conclusions:
The VHI test should be included in complex analysis of the effects of intensive rehabilitation.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
