Integrated entrainment system for testing the autonomic nervous system in health and disease

A physiological system sometimes includes oscillations as part of the control function. By using entrainment techniques and suitable frequency analysis of periodic body signals, it is possible to obtain valuable information on the autonomic system and body control mechanism in health and disease. A description is given of an integrated entrainment system using a thermal, respiration, and blood-pressure entrainment technique, as well as the processing and analysis of these signals using frequency analysis (FFT). The results indicate that this approach will be valuable in assessing the autonomic system function as well as predicting its condition.<>
