About this study

Official title: High-intensity Strength Training in Patients With Idiopathic Inflammatory Myopathies: Changes in Quality of Life, Muscle Strength, Function and Myocellular Parameters

This study evaluates the effects of a high-intensity strength training in patients with myositis with the primary outcome being quality of life (SF-36). The study is designed as a parallel group randomised controlled trial with an intervention group and a control group.

Read the detailed description

Overall aim:

To investigate the effect of high-intensity strength training on quality of life, muscle strength, physical function, and disease activity in patients with myositis

Study design:

60 myositis patients will be included in a 16-week high-intensity strength training study. Patients will be randomly allocated into 2 groups (strength training and control) in a 1:1 ratio.

User involvement:

Myositis patients has been recruited to a patient advisory board. The advisory board's objective is to give patient-oriented project feedback, thus improving the overall research project.

Intervention:

Two training session per week for 16 weeks. Sessions consists of 3 sets of each exercise corresponding to 10 RM. Training progression will be accounted for and training loads will be evaluated weekly. The training protocol will be a full-body protocol, i.e. all major muscle groups will be engaged during each training session.

Outcomes:

The primary outcome is the Physical Component Summary Measure from the quality of life questionnaire (SF-36). Secondary outcomes include strength measures, functional tests, disease activity measures, questionnaires (e.g. International physical activity questionnaire), DEXA whole body scans, blood samples and muscle biopsies.

What participants receive

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

  • High-intensity strength trainingOther

    Also called High-intensity resistance training

    The high-intensity strength training protocol will consist of 2 training sessions per week. The first two weeks will be familiarisation training, where each exercise will be performed in three sets of 10 repetitions at an intensity of 15 repetitions maximum (RM). At week three each session will consist of 3 sets of each exercise corresponding to 10 RM, which will be kept for the remaining part of training intervention. The weights for each exercise will be adjusted throughout the intervention period, so the training load will correspond to 10 RM for each exercise in the entire intervention period.

    Standard 12-lead ECG at 25 mm/s is recorded and analyzed according to standard published criteria (48-50). According to the Minnesota coding the PQ-interval is measured and presence of 1st, 2nd (including Mobitz type 1 and 2), and 3rd degree of AV block are noted. Additional measures will include: P-wave duration (≥ 2.5 mm in any of leads II, III, aVF), QRS duration (≥ 120 ms in any of leads I, II, III, aVL, aVF), QTc duration (> 450 ms), atrial fibrillation and flutter.

The record lists 1 site in Denmark. 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?

Quality of life (health survey (SF-36) subscale: Physical Component Summary) (time frame: 16 weeks). 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 NCT04486261, which also lists 5 linked publications.

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 10 Apr 2024.
