Randomized Controlled Trial of Voice on Children With Vocal Nodules

Exclusion criteria

• ✕. Children 6 to10 years of age will be enrolled. The rationale for this age range was previously noted. In brief, children in this age range (a) have similar educational and social exposures; (b) will likely not yet encounter pubertal changes affecting the larynx; and (c) are relatively cognitively homogeneous. Moreover, children in this age range have the ability to cooperate with voice therapy and have also been shown to be tolerant of stroboscopic examination. Finally, the voice therapy regimen in this protocol has been shown to be clinically effective for many children in this age range.
• ✕. Voice-related quality of life must be affected to the extent that baseline PVRQOL scores are \<87.5 (on a scale of the worst, 0, to the best, 100) at the time of entry into the trial. Based on previously published data, this subset of scores will be clearly distinct from scores in children with normal voices. In addition, scores \<87.5 represent worse than average scores among children diagnosed with vocal fold nodules.
• ✕. Dysphonia duration prior to randomization must be at least 12 weeks, in order to ensure that vocal dysfunction is chronic in nature.
• ✕. Hearing in better ear of 35 dB or better.
• ✕. Agreement by informed consent from the parents and informed assent from the child participant with anticipated commitment to compliance throughout the follow up period of 3 months is necessary for enrollment which includes time commitment of up to 3 hours per week to therapy sessions and homework.
• ✕. Vocal fold nodules are a pathology that predominantly affects males. A number of studies and the databases utilized to track this pathology at the clinical sites indicate that the male: female ratio is approximately 7:3. Given this background, the enrollment plan for the current investigation will seek to have a 30% female representation of the patients enrolled in this study to ensure appropriate gender representation. Additionally, patients with a diagnosis of pediatric vocal fold nodules predominantly are found in Caucasian populations. However, in accordance with the National Institute of Health Revitalization Act of 1993 the inclusion of minorities in this proposal will be targeted to the representation of minorities in the greater Boston, Philadelphia and Milwaukee metropolitan regions.
