Autonomic activity, pain, and perceived health in patients on sick leave due to stress-related illnesses.
OBJECTIVE
The aim of the present study was to compare autonomic activity, pressure-pain thresholds, and subjective assessments of health and behavior between patients with stress-related illnesses and healthy control subjects.


METHODS
Twenty sick-listed patients with stress-related illnesses and 20 age- and gender-matched healthy subjects performed tests of autonomic regulation and algometric tests, and completed questionnaires about physical and mental health and behavioral patterns.


RESULTS
Patients exhibited higher autonomic reactivity to cognitive and physical laboratory tasks (p < 0.05), and had lower pressure-pain thresholds in the shoulders and lower back than healthy control subjects (p < 0.05). Furthermore, the patients rated considerably poorer health and health behavior than the control subjects (p < 0.05).


CONCLUSIONS
The results indicate an engagement of the autonomic nervous system in stress-related illnesses. Furthermore, they show that patients with stress-related illnesses experience symptoms of musculoskeletal pain, and it is therefore recommended that assessments of musculoskeletal pain be incorporated in the clinical examinations and the rehabilitation of patients with stress-related illnesses.
