Abstract:
We examined 47 men exposed to whole-body vibration for a long time (average 9.8 years) and tested esophageal motility. The following parameters were measured: mean pressure in the body of esophagus during the passing of peristaltic wave, maximum value of pressure during the passing of peristaltic wave, mean and maximum duration of spasm and peristaltic wave transmission velocity was calculated. In over 1/4 exposed to whole-body vibration disorders of esophagus motility were observed. These disorders are probably a consequence of vocational exposure to whole-body vibration.
