On the measures collected, a descriptive statistical analysis and distribution will be studied. Initial instrumental and clinical data from FOIS scale (The Functional Oral Intake Scale), PAS (Penetration-Aspiration Scale), Pooling Score (Farneti et al.); Cranial nerves test will be analyzed using parametric (t-test) and non-parametric (Wilcoxon test) tests with a p-value considered significant if <0.05, while longitudinal variations will be analyzed using ANOVA for repeated measurements. In addition, the effect size (Cohen's d) of the difference between the instrumental and clinical evaluation scales average before and after training in both groups will be calculated. This will allow to have an estimate of training effectiveness to perform a power study and plan a wider experimental study for validating the method.
