The Efficiency of Conditioned Pain Modulation is Associated With Levels of Pain Catastrophizing in Patients With Chronic Low Back Pain

Aalborg University·interventional·Posted Aug 23, 2018·Updated Dec 24, 2018

In Brief

A clinical study evaluating PPT measurement, Pain catastrophizing scale, and 1 other intervention for Catastrophizing Pain and 2 related conditions. Completed, enrolled 44 participants across 1 site.

Detailed Summary

This study evaluates the potential association between pain catastrophizing thoughts and the ability to dampen pain via endogenous descending inhibition. Half of the participants are persons with chronic low back pain and the other half are age and gender-matched controls

Interventions

PPT measurementother

The sensitivity to pressure which is gradually increased is assessed. The procedure is performed at the back and the lower leg

Pain catastrophizing scaleother

A validated questionnaire that measures three domains of pain-related catastrophizing thoughts: helplessness, rumination and excessive magnification

Cold Pressor Testprocedure

The participant submerges one hand into a tank of cold (5 deg C), circulating water. The procedure is commonly know to decrease the sensitivity to pressure (PPT procedure) so that a difference appears in pain sensitivity when comparing PPT values before and after the procedure
