Neck pain may disrupt your Body's 'Autopilot' system

This study looked at whether people with long-term neck pain have differences in their autonomic nervous system (the part that controls things like heart rate) compared to healthy people. Researchers measured heart rate variability in 56 participants while lying down, sitting, standing, and during a hand-grip test. The goal was to better understand how chronic neck pain might affect the body's stress and recovery responses.
