Comparative analysis of the autonomic nervous system response during movement representation in healthy individuals and patients with chronic low back pain: a prospective cohort study.

The results showed that AO and MI training in the PG and CG resulted in similar but not identical ANS activation, with slightly higher activation in the PG. The differences in the PG could be associated with kinesiophobia when visually exposed to low-back movements that could be interpreted as hazardous or unsafe.
