Background and Objectives This study compares Vocal Fatigue Index (VFI) scores according to the presence or absence of external laryngeal tension in hyperfunctional voice disorder. And through this, it is to confirm the usefulness of VFI to hypertension of extrinsic laryngeal muscles.Materials and Method The subjects were 61 female diagnosed with hyperfunctional voice disorder (hypertension group 41, non-hypertension group 20). The author palpated extrinsic laryngeal muscles for evaluation of hypertension and classified them as the presence or absence. The voice measurements were jitter, shimmer, Korean-Voice Handicap Index-10 (K-VHI-10), and Korean-Vocal Fatigue Index (K-VFI). The voice compared were according to the diagnosis and presence of hypertension only for patients with hyperfunctional voice disorder.Results As a result of comparing the voice measurement according to the presence or absence of hypertension, there was no significant difference in the acoustic variables, K-VHI-10 and K-VFI-Total, K-VFI-Fatigue. Whereas, K-VFI-Physical (p=0.006) and K-VFI-Rest (p=0.022) were significantly higher in the hypertension group.Conclusion These results indicate that the hypertension group has more physical discomfort and less voice recovery than the group without hypertension. It means that K-VFI can measure the physical discomfort and limitations of voice recovery due to hypertension of the external laryngeal muscle. The VFI can be used as one of the methods to evaluate the hypertension of the external laryngeal muscle in Hyperfunctional voice disorder.

Intrinsic Laryngeal Muscles

Eight patients with voice tremor were studied to characterize laryngeal muscle involvement. Electromyographic (EMG) recordings were made from intrinsic laryngeal muscles, simultaneously with some extrinsic laryngeal muscles, respiratory movement, and voice recordings during respiration, whisper, and phonation. Spectral measures were used to determine the tremor frequency and the prominence of spectral peaks in the EMG, respiratory and acoustic signals, while correlation coefficients were computed between pairs of tremulous EMG signals to measure the synchrony of tremor between muscles. The intrinsic laryngeal muscles were tremulous during respiration and speech, with the thyroarytenoid most often involved. Tremor was also detected in some of the extrinsic muscle recordings and the percentage of muscles with tremor was higher during phonation than during whisper or respiration. Time delays were found between tremor oscillations in laryngeal muscles. Because the thyroarytenoid was affected in all the patients studied, botulinum toxin injections may be beneficial in treatment of this voice disorder.

ABSTRACT Objective: to analyze the association between voice disorder and aspects related to breathing mode in children, according to sex. Methods: 250 children, aged six to nine years, attending a public school in São Paulo city, were selected. The collection consisted of spontaneously audio recorded speech samples. The breathing mode was evaluated for lip resting posture and nasal flow. Three audiologists performed the perceptual evaluation of the voice quality, with the help of GIRBAS scale. The results were associated using the chi-square test (p = 0.05). Results: 50.4% females and 49.6% males. As for the overall grade (G), 12.8% had voice disorder with respect to voice quality. In the breathing mode, 36.8% presented alterations in lip posture and 71.2%, in nasal flow. The associations between voice disorder and gender (p = 0.96), lip posture (p = 0.38) and nasal flow (p = 0.18) and between alterations in the nasal flow and sex (p = 0.449) were not confirmed. The association between lip posture and sex revealed significant differences in favor of males (p = 0.003). Conclusion: there was no statistically significant difference associating voice disorders with breathing mode (lip posture and nasal flow) and gender.

Extrinsic Laryngeal Muscles

The purpose of this study was to determine the effect of a vocal loading task on submandibular muscular activity and acoustic measures of vocal function. Surface electromyography (sEMG) directly assessed muscle activation related to extrinsic laryngeal muscles, and these findings were compared to the acoustic measurements of cepstral peak prominence, low to high spectral ratio, semitone range, and amplitude reflecting the function of intrinsic laryngeal muscles. These measurements were taken from 14 healthy, young adults of the Texas Christian University student population before and after reading Harry Potter and the Sorcerer’s Stone for 30 minutes at a volume of at least 75 decibels (dB). Results indicated consistent trends in which acoustic measurement showed more periodic vocal fold movement and reduced vocal range, and sEMG measurement showed reduced muscle activation. An elevated acoustic amplitude suggested that increasing vocal intensity could be a compensatory strategy for individuals with vocal fatigue, but further study is required to test this theory in a larger sample size.
