1ICS = Intelligibility in Context Scale; 2CFCS = Communication Function Classification System; 3VSS = Viking Speech scale; 4CAP = Capacity Profile Voice and speech; 5MACS = Manual Ability Classification System; 6GMFCS = Gross Motor Function Classification System; 7FOIS = Functional Oral Intake Scale. *Data are presented as Spearman correlation coefficients. **No linear association was found between the p-RDA severity scales and the Vignos and Brooke scale (n = 6 children), and therefore correlations with the Spearman correlation coefficient could not be reported.
