As a practitioner working with clients experiencing intermittent aphonia, you know the challenges that come with this condition. Recent research by E. Thayer Curry provides valuable insights into vocal fold frequency in individuals with intermittent aphonia. Here are five expert tips to improve your therapy sessions based on the findings of this study.
1. Understand the Importance of Frequency Levels
The study indicates that clients with intermittent aphonia have a significantly lower median vocal fold vibration frequency (96 Hz) compared to normal speakers (132 Hz). This lower frequency level is associated with increased periods of aperiodic phonation. Focusing on raising the fundamental frequency during therapy can help mitigate these issues.
2. Incorporate Frequency Movement Exercises
According to the research, the experimental subject exhibited more upward inflections with a greater extent than normal speakers. However, both upward and downward inflections were associated with aperiodicity, particularly at lower frequencies. Incorporate exercises that encourage smooth and consistent frequency movements to reduce aperiodic vibrations.
3. Emphasize the Role of Vocal Fold Tension
The study found that a decrease in vocal fold tension tends to result in greater aperiodicity. Conversely, increasing vocal fold tension can help reduce aperiodic vibrations. Use exercises that gradually increase vocal fold tension, such as sustained phonation at higher pitches, to improve vocal consistency.
4. Monitor and Adjust Reading Performance
The client's reading performance was slower (22.8 seconds) compared to normal speakers (17.4 seconds). Slow reading may contribute to prolonged periods of aperiodic phonation. Encourage clients to read passages at a steady, slightly faster pace to minimize these periods and improve overall vocal quality.
5. Track Progress with Acoustic Analysis
Quantitative measures of frequency and aperiodicity were crucial in understanding the client's vocal behavior. Implement similar acoustic analysis tools in your practice to track progress and adjust therapy strategies accordingly. This data-driven approach will provide a more confident basis for continued therapy.
By incorporating these expert tips into your therapy sessions, you can help your clients with intermittent aphonia achieve better vocal outcomes. For a more in-depth understanding, we encourage you to read the original research paper.
