Laryngeal diadochokinesis (LDDK) is an assessment of laryngeal motor function that provides information regarding neuromotor maturation and the integration of the structures needed for phonation (Modolo, Berretin-Felix, Genaro, & Brasolotto, 2011). Laryngeal diadochokinesis has clinical relevance because it offers a valid measurement of neuromotor function and vocal fold integrity. However, current research does not provide evidence regarding the degree to which speech-language pathologists can be reliable in their LDDK measurements in clinical settings. In order for LDDK to be clinically useful, however, there must be evidence that it can be a reliable measure. This study assessed the reliability of LDDK when graduate student clinicians use the pencil dotting method of data collection. Reliability was tested using both abductory and adductory stimuli to determine if a difference in interrater reliability among the two stimuli was present.
