Surface Gastrograms as Measures of Gastric Motility

  • Rupert Hölzl


Since the early observations by Beaumont (1833), a number of studies have been reported on the psychophysiology of stomach secretory and electromotor activity. The latter, which serves as the necessary mixing and transport functions of the stomach for digestion, has been evaluated by various techniques. Beaumont used direct observation of a part of the stomach wall in a patient with a large fistula and found marked changes in secretory and contractile activity of the stomach under psychological influences including strong emotions and anticipation of meals. A century later Wolf and Wolff (1943) used this method in a more systematic study of their famous patient, Tom, to show that the motor activity of the fistulated stomach section changed with different emotional states. Whether hyper- or hypomotility was observed depended on the kind of emotion elicited (cf. Stern, Chapter 9, this volume).
