Summary

Professional voice users experiencing vocal issues can benefit from a combined rehabilitation program. This approach significantly improved voice function and reduced vocal handicap, regardless of diagnosis or treatment order.

Area of Science:

  • Speech and Hearing Sciences
  • Occupational Health
  • Rehabilitation Medicine

Background:

  • Professional voice users represent a significant portion of the workforce, and voice disorders can negatively impact their careers and incur costs.
  • Vocal problems in this population range from subjective complaints like throat pain and vocal fatigue to objective findings such as benign vocal fold lesions.

Purpose of the Study:

  • To investigate the effectiveness of a combined voice rehabilitation program for professional voice users.
  • To compare treatment outcomes between two groups of professional voice users: those with dysphonia and those with vocal fold lesions.

Main Methods:

  • A repeated measures study involving 18 professional voice users.
  • Participants received a 5-week program of expiratory muscle strength training followed by voice therapy, or vice versa.

  • Outcome measures included maximum expiratory pressure (MEP), Voice Handicap Index (VHI), Vocal Rating Scale (VRS), and acoustic/perceptual voice analyses.

    • Main Results:

    • Significant improvements were observed in MEP, VHI scores, and VRS scores.
    • Enhancements in subglottal pressure for loud intensity, phonetogram area, and dynamic range were noted.
    • No significant differences in outcomes were found based on laryngeal diagnosis or treatment order.

    Conclusions:

    • The combined voice rehabilitation program demonstrated success in improving vocal function for professional voice users.
    • This multimodal approach appears effective for remediating vocal problems in this occupational group.
    • The findings suggest that a combination of therapies is beneficial, irrespective of the specific vocal diagnosis or the sequence of interventions.
