title: Combined glottographic changes in the elderly.
abstract: This study investigates by combined glottography the effect of the anatomical changes of ageing on laryngeal movement during the vibratory cycle. 10 adult males less than 25 years of age were compared to 10 males over 60 years of age. The speed quotient was increased in the elderly group; thus, ageing in the larynx results in a slowing of the opening of the vocal folds. This may account for the different voice quality in the elderly. The clinician must consider the subject's age when interpreting speed quotient values.
