“…In the United States, over one million or 6 to 9%1 of all children suffer from dysphonia 2. Hoarseness can be detrimental to children both psychosocially3, 4 and academically 5. Hence, early identification and restoration of optimal vocal health is critical.…”

Objectives/Hypothesis Aim of the study is to quantify differences in spatiotemporal features of vibratory motion in typically developing pre-pubertal children and adults with use of high speed digital imaging. Study Design Prospective case-control study. Methods Vocal fold oscillations of 31 children and 35 adults were analysed. Endoscopic high-speed imaging was performed during sustained phonation at typical pitch and loudness. Quantitative technique of Phonovibrogram was used to compute spatiotemporal features. Spatial features are represented by opening and closing angles along the anterior and posterior parts of the vocal folds, as well as by left-right symmetry ratio. Temporal features are represented by the cycle-to-cycle variability of the spatial features. Group differences (adult females, adult males, and children) were statistically investigated. Results Statistical differences were more pronounced in the temporal behavior compared to the spatial behavior. Children demonstrated greater cycle-to-cycle variability in oscillations compared to adults. Most differences between children and adults were found for temporal characteristics along the anterior parts during closing phase. The spatiotemporal features differed more between children and males than between children and females. Both adults and children showed equally high left-right symmetry. Conclusions Results suggest a more unstable phonation in children than in adults yielding increased perturbation in periodicity. Children demonstrated longer phase delay in the anterior/posterior and medio-lateral parts during the opening phase compared to adults. The data presented may provide the bases for differentiating normal vibratory characteristics from the disordered in the pediatric population and eventually assist in aiding the clinical utility of high speed imaging.

PURPOSE The aim of this study is to quantify and identify characteristic vibratory motion in typically developing prepubertal children and young adults using high-speed digital imaging. METHOD The vibrations of the vocal folds were recorded from 27 children (ages 5-9 years) and 35 adults (ages 21-45 years), with high speed at 4,000 frames per second for sustained phonation. Kinematic features of amplitude periodicity, time periodicity, phase asymmetry, spatial symmetry, and glottal gap index were analyzed from the glottal area waveform across mean and standard deviation (i.e., intercycle variability) for each measure. RESULTS Children exhibited lower mean amplitude periodicity compared to men and women and lower time periodicity compared to men. Children and women exhibited greater variability in amplitude periodicity, time periodicity, phase asymmetry, and glottal gap index compared to men. Women had lower mean values of amplitude periodicity and time periodicity compared to men. CONCLUSION Children differed both spatially but more temporally in vocal fold motion, suggesting the need for the development of children-specific kinematic norms. Results suggest more uncontrolled vibratory motion in children, reflecting changes in the vocal fold layered structure and aero-acoustic source mechanisms.

“…15,24,28 Voice disorders impact daily voice function as well as a child's personal, social, and academic development. 4,29,30 In summary, voice disorders have two important consequences for children. First, a chronic voice problem may impact the laryngeal mechanism leading to pathological changes to the laryngeal tissues.…”

The Association of a Preschool Voice Education Program with Changes in Yelling Frequency

Voice problems in children can occur as early as infancy. Early onset of voice problems can carry social and academic penalties, and negatively affect voice in adolescence or adulthood. Unfortunately, only 1% of school-aged children receive voice therapy despite a 6 to 24% prevalence of voice disorders in school-aged children. One alternative may be to use a classroom-based voice education curriculum to effectively reduce yelling frequency, the most common behavior associated with phonotrauma-related voice problems in children. A classroom-based voice education curriculum was administered to preschool children by the preschool speech-language pathologists in a university-affiliated program. Classroom teachers provided cueing and reinforcement of curriculum strategies for 8 weeks following the program. Baseline frequencies of participant yelling behaviors were compared with postprogram frequencies. Results demonstrated significant reduction in yelling frequencies from pre- to postprogram, particularly in those judged as high-frequency yellers prior to the program. Important factors for future consideration are discussed.
