The efficacy of voice therapy for pediatric voice-disordered population: A systematic review and meta-analysis

Abstract

BACKGROUND: Behavioral characteristics of children are highly associated with a phonotraumatic voice use pattern, and hence the development of dysphonia. Voice therapy is always the first-line intervention approach for dysphonia in children. Cohort studies and recent experimental studies with control groups have provided conflicting evidence on the efficacy of voice therapy compared to no intervention or other interventions. To date, there has not been any systematic review done to evaluate the evidence of voice therapy and compare treatment options for children with dysphonia secondary phonotrauma. OBJECTIVE: This systematic review aimed to investigate on the efficacy of voice therapy for children with dysphonia secondary to phonotrauma compared to no intervention or other interventions. METHODS: Two independent reviewers identified studies through searching on electronic databases and handsearching. They selected studies, extracted data; and evaluated methodological quality of the included studies using appraisal items adapted from Critical Appraisal of Systematic Review or Meta-Analysis (CASM). Meta-analysis was carried out for studies at low risks of bias, while a descriptive synthesis was carried out for studies at high risks of bias. RESULTS AND DISCUSSION: The systematic review and meta-analysis will guide clinical practice in prioritising treatment options for pediatric population. Learning Outcome: 1. Discuss the evidence of voice therapy for pediatric voice-disordered population. 2. Discuss the future clinical / research directions on management of pediatric voice.
