A Cross-Sectional Study of Comparing Diadochokinesis Parameters Between Normals and Post-Mandibulectomy

Abstract

Background and Aim: Oral cancer has been the second most common cancer in India. Mandibular cancer has been in raise due to the use of tobacco-related products. The influence of mandibular cancer before and after surgery has not been studied much. Hence, the current study aimed to evaluate the effect of mandibulectomy on mandibular stability through the assessment of diadochokinetic measurement. Materials and Methods: Thirty-nine subjects served as participants for the present study. Out of which, 30 normal (group 1) and 9 individuals of the mandibular lesion (group 2) as a clinical group. Study material included rapid repetition of /pa/, /ta/, /ka/ and /pataka/ sequence for 6 seconds duration. Three trials have been obtained from all participants. Data were analyzed using Praat software and an independent t-test and paired t-test was used for statistical analysis. Results: Results showed a reduced SMR rate as compared to the control group in the postoperative condition. AMR rate of only /pa/ syllable was found to be statistically significant at a lower rate in post-operative conditions. The acoustic parameters of syllable duration, inter syllable duration, and peak intensity of each consonant /p/, /t/, and /k/ did not vary across groups. Conclusion: The study indicated that the mandibular stability was found to be reduced following mandibulectomy. The reduced AMR rate of /pa/confirmed the effect of mandibular surgery on the production of anteriorly positioned speech sounds. The present study stresses the importance of incorporating the DDK parameters in speech assessment to understand mandibular stability.

Keywords: Mandibulectomy, DDK, speech motor coordination

Introduction

Diadochokinetic rate (DDK) measurements reflect the motor speech coordination and also raising and lowering of the mandible or protrusion and retracting the tongue. [1] It provides information on speed, accuracy, and continuity measures of speech production. [2].

DDK measurements are carried out by rapid repetition of syllables /pa/, /ta/, and /ka/ and /pataka/. Studies have reported that DDK provides information on variation observed in mandibular stability.[3] The mandibular lesions can contribute to anatomical changes thus affecting mandibular stability.

Need for the Study

There has been a very limited study on DDK rates in individuals who have mandibular cancer or the individuals who underwent mandibulectomy. There is a need to carry out a longitudinal study by comparing the performance of speech motor control mechanisms before and after they undergo mandibulectomy. There is also a dearth in studies comparing the normative group with mandibular lesions for understanding the effect of lesion on motor speech coordination. A comparison of a normative group with individuals who have undergone mandibulectomy can also assist the speech pathologists and surgeons in providing knowledge of the mandibular stability of patients.
