Article Synopsis
- The study aimed to evaluate how effective nonlinear dynamic analysis measures are in diagnosing voices with normal, benign, and malignant disorders, while also seeing how these measures correlate with perceptual ratings of voice severity.
- Various metrics were assessed, including Jitter%, Shimmer%, and nonlinear dynamics like NEDR and ROD, with results showing that most metrics could differentiate voice disorders, although SCR struggled to distinguish benign from malignant cases.
- The findings suggest that while both perturbation and nonlinear dynamic analyses are useful, NEDR and ROD may be particularly effective in identifying severe voice disorders, making them valuable tools in clinical practice.
Objective: The objective of this study is to introduce a novel method for semi-occluded vocal tract (SOVT) therapy called "controlled supraglottic pressure phonation," determine the mechanism by which supraglottic pressure contributes to lowering impedance during SOVT therapy, and provide the optimal supraglottic pressure range for SOVT exercises.
Methods: Twenty-five human subjects were assigned to one of five supraglottic pressure levels, 0, 2, 4, 6, and 8 cmH2O, which were controlled through a continuous positive airway pressure device. Subjects were asked to phonate during both a short- and long-duration task, in which vocal properties were measured before and after.
Objective: Among music majors with only 18 months of training, supraglottal activities and aerodynamic parameters were studied to facilitate understanding of the influence of voice training on characteristics of voice production.
Methods: Twenty-three students at the Xiamen Music School were examined over the course of 18 months of singing training. Only 17 students completed all data collection sessions.
Objective: Acoustic parameters of voice were studied in music majors throughout 18 months of training to understand the influence of voice training on voice.
Methods: Twenty-three students from Xiamen Music School between 12 and 15 years old were enrolled. Acoustic examination was performed three times- every 6 months for 18 months.
Objective: To investigate the value of diffusion tensor imaging (DTI) in the evaluation of vocal fold tissue microstructure after recurrent laryngeal nerve (RLN) injury.
Methods: Six canines were divided into 2 groups: a unilateral vocal fold paralysis group (n = 4) and a control group (n 2). The RLN was cut in the unilateral vocal fold paralysis group, and no intervention was applied in the control group.
