High-Intensity vs. Preferred-Intensity Resistance Training in Fibromyalgia

Brazil36 participantsStarted 2024-07-01

Plain-language summary

This randomized crossover clinical trial aims to verify and compare the effects of high-intensity (HIG) and preferred-intensity (PIG) resistance training on the health of women with fibromyalgia (FM). Secondary objectives include verifying differences after 4, 8, and 16 sessions, as well as evaluating the proportion of participants who achieve the minimal clinically important difference in the disease impact/severity outcome. Patients included in the study will be randomized into two groups: HIG and PIG. Sixteen training sessions will be conducted twice a week, with each session lasting approximately 60 minutes. Subsequently, patients will undergo a minimum 8-week washout period (detraining) and will then be allocated to the other intervention group. The primary outcome is disease impact evaluated using the Revised Fibromyalgia Impact Questionnaire (FIQR). Secondary outcomes include mood states evaluated by the Brunel Mood Scale (BRUMS), sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI), anxiety levels evaluated with the Beck Anxiety Inventory (BAI), and depression levels evaluated with the Beck Depression Inventory (BDI). Attendance and absence data will also be collected, as well as information regarding program discontinuation.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
