No results posted yet for this study

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

Conditions

  • Catastrophizing Pain
  • Pain, Somatic
  • Chronic Low Back Pain

Interventions

DIAGNOSTIC_TEST

PPT measurement

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

DIAGNOSTIC_TEST

Pain catastrophizing scale

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

PROCEDURE

Cold Pressor Test

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
