Abstract
[Purpose] To investigate the reliability of the measurement of intestinal peristalsis using an Actigraph micro-sound sensor. [Subjects] Nine healthy subjects. [Methods] Noise was simultaneously measured by three sensors, three times, and the intraclass correlation coefficient and test-retest reliability were calculated. Next we measured intestinal peristaltic sounds, heart sounds, breathing sounds, and investigated whether breathing sounds and heart sounds affected the intestinal peristaltic sound measurement. [Results] The intraclass correlation coefficient was “good” at 0.66, and the test-retest reliability was also “good.” It was possible to measure the intestinal peristaltic sound without interference from breathing and heart sounds. [Conclusion] We confirmed the reliability of the Actigraph micro-sound sensor, and it was possible to measure intestinal peristaltic sounds without interference from breathing and heart sounds.
