Application of parent-child play-based vocal training in school-age children with vocal fold nodules

To investigate the effects of parent-child interactive medical games combined with voice training on the vocal function and quality of life of school-aged children with vocal nodules, and to identify effective methods for improving the vocal function of children with vocal nodules.

Eighty school-aged children with vocal nodules were randomly assigned to a control group (n = 40) and an intervention group (n = 40). The control group received conventional voice training, while the intervention group underwent parent-child interactive medical games combined with voice training. After an 8-week intervention period, objective voice acoustic parameter scores, pediatric voice disorder index scores, and voice-related quality of life scores were compared between groups.

Forty subjects in each group completed the study. After 8 weeks of intervention, the intervention group demonstrated significantly improved scores for Jitter, Shimmer, and F0 compared to the control group. Additionally, the intervention group exhibited lower scores on the Pediatric Voice Disorder Index and lower scores on voice-related quality of life measures than the control group (all P < 0.01).

Combining parent-child interactive medical games with voice training can improve objective acoustic parameters of the voice in school-aged children with vocal nodules, reduce voice disorders in this population, enhance their quality of life, and promote vocal fold recovery.
