J Rehabil Res Dev. 2015;52(4):XX–XX. http://dx.doi.org/10.1682/JRRD.2014.06.0154 Slideshow Project DOI:10.1682/JRRD.2014.06.0154JSP Aim – Compare autonomic response to painful stimuli between patients with acute and chronic whiplash-associated disorder (WAD) and healthy controls. – Examine role of autonomic nervous system for explaining inefficient endogenous pain inhibition in acute WAD. Relevance – Patients with acute WAD demonstrate inefficient endogenous pain inhibition and may experience dysfunction in autonomic nervous system reactivity to pain.

Skin conductance and heart rate variability (HRV) parameters monitored continuously during conditioned pain modulation.

Endogenous pain inhibition is unrelated to autonomic responses in acute whiplash-associated disorders.

Interaction effect of skin conductance response to pain but not in HRV responses in any group. No significant correlations between pain, pressure pain thresholds, pain inhibition, and any autonomic parameters in patients with acute WAD.

Endogenous pain inhibition is unrelated to autonomic responses in acute whiplash-associated disorders.

Dysfunctional conditioned pain modulation appears unrelated to autonomic responses to pain.
