A new EPG protocol for assessing DDK accuracy scores in children : a Down's syndrome study

Abstract

Recent research has suggested that eliciting diadochokinetic (DDK) rate and accuracy in young children is difficult [1], with analysis being timeconsuming.This paper details a new protocol for assessing DDK in young children or children with intellectual impairment (Down's syndrome) and a method for calculating accuracy scores automatically. Accuracy scores were calculated from auditory and electropalatographic analyses and found to correlate in some instances. The children with Down's syndrome presented with similar DDK rates to typically-developing children but reduced accuracy.
