An Ultrasound Investigation of Tongue Shape in Stroke Patients with Lingual Hemiparalysis

Stroke can cause hemilateral paresis of the tongue. The present study investigated the functional consequences of a lingual hemiparalysis on the symmetry and the grooving of the tongue in the coronal plane during the production of vowel-consonant-vowel sequences. The hypotheses were that, because of the lingual hemiparalysis, the stroke patients' tongue shapes would be (1) more asymmetrical and (2) less grooved than the tongues of the control speakers.
