Cognitive Mechanisms in Pediatric Voice Therapy - An Initial Examination

Area of Science:

• Pediatric Otolaryngology
• Speech-Language Pathology
• Neuropsychology

Background:

• Voice disorders are common in children, with behavioral voice therapy being a primary treatment for benign vocal fold lesions.
• The influence of cognitive mechanisms on the effectiveness of voice therapy for pediatric patients remains underexplored.

Purpose of the Study:

• To investigate the preliminary relationship between cognitive abilities and voice therapy outcomes in children with benign phonotraumatic vocal fold lesions.
• To gather data for future, larger-scale studies on cognitive factors in pediatric voice treatment.

Main Methods:

• Six children (aged 4-9) with vocal fold nodules underwent cognitive testing using the NEuroPSYchological (NEPSY-II) Assessment.
• Participants completed a standard voice therapy program, "Adventures in Voice."
• Voice recordings were analyzed acoustically (Cepstral Spectral Index of Dysphonia) and perceptually (visual analog scales) before and after therapy, with results correlated to NEPSY-II scores.

Main Results:

• Several cognitive functions, including Design Fluency, Inhibition, Fingertip Tapping, and Narrative Memory, showed favorable correlations with voice therapy outcomes.
• Age was found to correlate with both cognitive test raw scores and perceptual voice outcomes.
• Specific scaled NEPSY-II scores for Auditory Attention, Design Fluency, Fingertip Tapping, and Narrative Memory were linked to all voice outcome measures.

Conclusions:

• The findings suggest a significant link between cognitive skills and voice therapy results in children with benign vocal fold lesions.
• Further investigation into the interplay of cognitive development and voice treatment efficacy is warranted.
• Larger sample studies are needed to build upon these initial findings and confirm the role of cognitive abilities in pediatric voice rehabilitation.
