Primary Outcome Measures

Name	Time	Method
<p>The main study parameter will be the feasibility of the counterconditioning<br /><br>intervention. This will be done by looking at the drop-out rate, by measuring<br /><br>participant*s satisfaction with the intervention; by examing what, according to<br /><br>the participants, is causing the possible increase and reduction of<br /><br>experimentally evoked pressure pain in the test phase of (counter)conditioning<br /><br>(e.g., the TENS device, the placebo or nocebo effect); by exploring the amount<br /><br>of experimentally-evoked pressure pain reported during the test phase of<br /><br>counterconditioning, whether this reduces over time, as well as the speed of<br /><br>this reduction.</p><br>
