Clinical Trial Summary

Pain can currently be quantified using quantitative sensory tests (QSTs). However, we lack knowledge concerning how relational and contextual factors impact these quantitative tests. We will examine how a standard QST battery is affected by "removing" the social and human interaction from the test session compared to usual QST testing where the participant is guided through the assessment by a research assistant. Our objectives are: 1. How is the QST affected when guided by a research assistant compared to guided by a computer 2. Does the level of the assessor's empathy affect the QST outcome 3. How do psychological factors affect the QST testing 4. are these outcomes affected by the patient profile (low back pain patients vs healthy controls)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Conditioned pain modulation effect [changes in kPa]	Between-group differences in conditioned pain modulation (CPM). The CPM [range -1000;1000 kPa] is measured as the change between a pressure pain threshold test before and after a cold pressor test (2 minutes of immersion the left hand in ice water].	Baseline
Secondary	Pressure pain threshold	Between-group differences in pressure pain threshold [range 0-1000 kPa] as measured before the cold pressor test	Baseline
