Clinical Trial Summary

The study's aim is to determine whether a short video aiming to optimize expectations regarding the effectiveness of progressive muscle relaxation (PMR) ist able to improve the actual effectiveness of PMR in comparison with a neutral (no video) control group.

Intervention

Behavioral:
• Progressive Muscle Relaxation (PMR)
All groups undergo a PMR session, but they differ regarding the treatment before the PMR session. Two groups watch a video before undergoing PMR, the control group reads a text before undergoing PMR. Progressive muscle relaxation (PMR) is a technique for learning to monitor and control the state of muscular tension. It was developed by American physician Edmund Jacobson in the early 1920s. The technique involves learning to monitor tension in each specific muscle group in the body by deliberately inducing tension in each group. This tension is then released, with attention paid to the contrast between tension and relaxation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in perceived/subjective relaxation	Participants are asked to rate how relaxed they feel at the moment at two time points (baseline and after the PMR intervention) on a questionnaire (VAS: item ranges from 0 (not relaxed at all) - 100 (very relaxed). Change scores are calculated (post- minus pre-scores).	Change from pre (baseline) to post scores (30 minutes later)
Secondary	Change in perceived stress	Participants are asked to rate how stressed they feel at the moment at two time points (baseline and after the PMR intervention) on a questionnaire (VAS: item ranges from 0 (not stressed at all) - 100 (very stressed). Change scores are calculated (post- minus pre-scores).	Change from pre (baseline) to post scores (30 minutes later)
Secondary	Change in physiological relaxation	Electromyography is used to assess participants' physiological relaxation status at baseline and after the PMR intervention. Change scores are calculated (post- minus pre-scores).	Change from pre (baseline) to post scores (30 minutes later)
