简要总结
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)

结局指标
主要结局
The Conditioned pain modulation effect [changes in kPa]
时间窗: 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\].
次要结局
- Pressure pain threshold(Baseline)
