Autonomic Differences in Heart Rate Variability Between Healthy and Chronic Low Back Pain Subjects

This study aims to evaluate the autonomic differences in heart rate variability (HRV) between healthy individuals and those with chronic low back pain. By analyzing HRV parameters, such as time-domain, frequency-domain, and non-linear metrics, this cross-sectional study seeks to explore the impact of chronic pain on the autonomic nervous system. The study will provide insights into parasympathetic and sympathetic modulation and its potential relationship with chronic pain symptoms. Participants include healthy adults and individuals with chronic low back pain aged 18-65.
