BIOPAC provides software and hardware that allows research teams to run autonomic function tests while collecting physiological data. Here are a few studies focusing on BIOPAC’s ability to record physiological signals during autonomic function testing.
The Internet, Sleep, and Heart Rate
Does internet usage lead to poorer sleep? Using a BIOPAC Data Acquisition System to measure cardiovascular autonomic function, these researchers found a correlation between length of internet usage, time of internet usage, and resting heart rate.

Comparing Autonomic Response
Through two autonomic function tests, active orthostasis and passive orthostasis, this study compared the autonomic response of individuals with and without intellectual disabilities. To compare the two groups, ECG data was collected using a BIOPAC Data Acquisition System.

White, Tracy Baynard, Bo Fernhall)
Understanding the Depths of Psoriasis
Psoriasis is known to affect both the skin and joints, but can it also affect the body’s autonomic function? Using autonomic function tests, including the Valsalva maneuver and cold pressor test, while collecting hemodynamic data with a BIOPAC Data Acquisition System, this scientist attempted to demystify the role of psoriasis in cardiovascular comorbidities.

BIOPAC’s two-part AFT series examines the essential role of Autonomic Function Tests in helping researchers identify a diagnosis, evaluate the prognosis, and assess treatment options for autonomic nervous system diseases. The AFT series demonstrates a standard battery of autonomic test protocols for cardiovagal, vasomotor adrenergic, and sudomotor function. It identifies standard testing protocols, illustrates setup with the help of video recordings of participants, and provides tips for analyzing AFT data. Part 1 focuses on Valsalva Maneuver, Deep Breathing, and Active Standing; Part 2 focuses on Isometric Handgrip Test, Cold Pressor Test, and Mental Arithmetic.
