title: [Subjective assessment of voice functions among teachers taking part in the rehabilitation program].
abstract: BACKGROUND
  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).
  
  
  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.
