About this study

Official title: Effects of Videos Aiming to Optimize Expectations on Effectiveness of Progressive Muscle Relaxation (PMR)

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.

Being tested
Progressive Muscle Relaxation (PMR)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Progressive Muscle Relaxation (PMR)Behavioural

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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).

    Measured: Change from pre (baseline) to post scores (30 minutes later)

Secondary outcomes (2)
  1. 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).

    Measured: Change from pre (baseline) to post scores (30 minutes later)

  2. 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).

    Measured: Change from pre (baseline) to post scores (30 minutes later)

Questions about this trial

What is this clinical trial studying?

A study testing Progressive Muscle Relaxation (PMR) in people with Experimental Group 1 (Video Personal Expert) and Experimental Group 2 (Video Factual Expert), run by Philipps University Marburg at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in perceived/subjective relaxation (time frame: Change from pre (baseline) to post scores (30 minutes later)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03330431, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2020.
