Masking description
The participants are blind to the study hypothesis and therefore the expected outcome of the tests performed
Intervention model description
Half the participants will start with intervention 1 after which they will crossover to intervention 2. The other half will start start with intervention 2 before crossing over to intervention 1.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain intensity | through study completion, an average of 90minutes | Pain intensity during the interventions is scored using a Visual Analog Scale or Numeric Rating Scale (0 = no pain and 10 = worst known pain) |
| Pain threshold | through study completion, an average of 90minutes | Pain threshold is defined as when the participants feel the sensation changing from an unpleasant feeling to a painful experience (measured in seconds) |
| Pain tolerance | through study completion, an average of 90minutes | Pain tolerance is when the participants no longer are able to withstand the pain (measured in seconds). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain catastrophizing | through study completion, an average of 90minutes | The pain catastrophizing score is measured by filling out the pain catastrophizing scale questionnaire. The pain catastrophizing scale consists of 13 sentences assessing pain-related thoughts or feelings. These are then divided into 3 domains: rumination, magnification and helplessness. The subject is asked to rate how well each sentence applies for them: 0 = not at all, 1 = to a slight degree, 2 = to a moderate degree, 3 = to a great degree and 4 = all the time. The total score on the questionnaire can lie between 0 - 52 where a higher score indicates higher levels of pain catastrophizing thoughts. |
