简要总结
The purpose of this study is to investigate if different emotional states could influence mechanical pain thresholds in individuals with chronic pain.
详细描述
Participants will be randomized into 4 different groups watching different short video-clips (2.20 min). The negative emotions group will watch an uncomfortable short video containing violence and blood, the positive emotions group will watch a video containing a stand-up comedy show, the neutral emotions group will watch a video about how to paint a house, and the control group will just wait for 2.20 min, without any instructions about what to think about. Pressure pain thresholds will be measured with an algometer before and after the video-clips.

结局指标
主要结局
Pressure pain thresholds will be measured in kPa
时间窗: The measurement takes place at the intervention session. First a baseline measurement is conducted, then comes the intervention and then the intervention measurement takes place.
Pressure pain thresholds will be measured in kPa using a handheld algometer (Somedic AB).
