Lower paraspinal reactivity with high depression may mark greater pain severity in chronic low back pain; hypothesis-generating and requires prospective validation.
Does symptom-specific physiological reactivity to stress predict pain severity in chronic low back pain patients?
A profile of lower paraspinal hyperreactivity combined with depressed affect may aggravate chronic low back pain.
Burns et al. (1997) studied this question.
