The bipolar electrode was attached on the parasacral region, and the intraluminal pressure of the ileal W pouch was recorded by means of an open-tip catheter (12 and 9 cm proximal from anus) for 30 minutes prior and following feeding. Spectral analysis by maximal entropy method was performed every 128 sec. Both spectrally analyzed electrical and pressure waves were piled up to make the running spectra. Spectral peaks of averaged spectra were found at 2.8 cycle per minute (cpm) and 8.1 cpm in pressure waves at 12 cm from anus. Those were found at 7.8 cpm in pressure waves at 9 cm from anus. Spectral peaks of the electrical activity were found at 1.4 cpm and 7.3 cpm. Therefore, spectral peak values were similar between intraluminal pressure and electrical waves which were thought to be the BER (basic electrical rhythm) in the terminal ileum. It was suggested that electrical activity reflecting pressure changes of the ileal W pouch could be recorded by surface electrodes on the parasacral skin.}, pages = {904--910}, title = {W型回腸嚢運動の経皮的記録に関する研究}, volume = {108}, year = {1994} }
