Sponsor's own description

The study examines the impact of music during colonoscopy on sympathetic - autonomic nervous system, whose activity is operationalized by biopotentials signals. The music is chosen by the patients themselves. The Null hypothesis: The comparison of the sympathetic - autonomic nervous system (operationalized by biopotentials) intensity between colonoscopy "with" vs. "without" music is not significant. Alternative hypothesis: The comparison of the sympathetic - autonomic nervous system intensity is significantly higher in colonoscopy "without" music vs. "with" music.
