Abstract In order to define the influence of age on pharyngeal constrictor peristalsis, four groups of individuals were examined with cineradiography (50 frames/s) during barium swallow. The speed varied between 6.3 and 21.3 cm/s (mean, 10.5). There was no significant difference between young nondysphagic volunteers and the three groups of dysphagic patients ages under 40, between 50 and 60, and over 75 years of age). However, the intrapersonal variation of peristaltic speed during three different swallows was small in young nondysphagic volunteers and large in dysphagic patients. The variation increased with age. Variation in speed is easy to register during cineradiography and should be considered as a criterion for definition of pharyngeal motor performance in dysphagic patients.
