Purpose: Regardless of age or disease stage, children with neuromuscular disorders (NMD) are at risk of developing dysphagia and/or dysarthria. It is important to screen these children regularly in order to detect and treat problems as soon as possible. To date, there are no standardized tools for screening for dysphagia and dysarthria in children with NMD (pNMD). Thus, children are not always referred for assessment by a speech language therapist (SLT). A new screening instrument for dysphagia and dysarthria has been developed, the Screeninglist Physician of the Diagnostic list for Dysphagia and Dysarthria in pediatric NMD (DDD-pNMD). The diagnostic accuracy was estimated in this study.
Methods: Sensitivity and specificity were assessed in 131 children aged 2.0-18.0 years by comparing the outcome of the Screeninglist Physician with the diagnosis of dysphagia and/or dysarthria established by an SLT.
Results: The sensitivity of the Screeninglist Physician was 88% and its specificity was 63%. The AUC was 0.83. The prevalence of dysphagia and/or dysarthria was 53%.
Conclusion: The Screeninglist Physician of the DDD-pNMD is the first valid screening tool for physicians to identify children with NMD with possible dysphagia and/or dysarthria, thereby enabling timely referral to an SLT.
