Abstract

Introduction

The movement of the tongue has been of concern for many years to the speech therapist. At one time tongue exercises were of prime importance in this field but due to the gross misuse of the exercises, they have now become of little importance. Only recently has the motor functioning of the tongue attracted renewed interest. Although the activity of the tongue has often been studied, none of the studies to our knowledge have included the control of jaw movement. Since the genio-glossus muscle serves as the bulk of the tongue and has its origin on the mandible, the importance of mandibular descent seems obvious. The purpose of this study is to investigate the diadochokinetic rate of tongue clicking under condition controlling the jaw movement.
