Overview
Brief 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:
- How is the QST affected when guided by a research assistant compared to guided by a computer
- Does the level of the assessor's empathy affect the QST outcome
- How do psychological factors affect the QST testing
- are these outcomes affected by the patient profile (low back pain patients vs healthy controls)
Investigators
Eligibility Criteria
Inclusion Criteria
- •Primary complaint of low back pain
- •No pain for healthy controls
- •No serious psychological or somatic disorders potentially interfering with the QST
Exclusion Criteria
- •Incomplete QST data
Outcomes
Primary Outcomes
The Conditioned pain modulation effect [changes in kPa]
Time Frame: Baseline
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\].
Secondary Outcomes
- Pressure pain threshold(Baseline)
