About this study

Official title: Does Strength Training in Fibromyalgia Affect Balance, Neuromuscular Performance and Symptoms? A 12 Week of a Randomized Controlled Trial

The purpose of this study is verify the effects of a 8 weeks strength training, on balance, neuromuscular performance and symptomatology of fibromyalgia.

Read the detailed description

Thirty participants will be recruited. Volunteers will be randomly assigned to the control group or experimental group. Before the training period, symptoms, balance and neuromuscular performance will be assessed. Participants in the experimental group will perform strength training twice a week (50 min each) for eight weeks. Then, four weeks of detraining will be completed.

What is being measured

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

  1. Balance

    Force plate

    Measured: Change from Baseline balance at week 9

  2. Balance

    Force plate

    Measured: Change from Baseline balance at week 12

  3. Balance

    Force plate

    Measured: Change from week 9 balance at week 12

  4. Neuromuscular performance

    Optical measurement system consisting of two transmitting and receiving cells to assess vertical jump and medicine ball to assess strength of the upper limbs.

    Measured: Change from Baseline neuromuscular performance at week 9

  5. Neuromuscular performance

    Optical measurement system consisting of two transmitting and receiving cells to assess vertical jump and medicine ball to assess strength of the upper limbs.

    Measured: Change from Baseline neuromuscular performance at week 12

  6. Neuromuscular performance

    Optical measurement system consisting of two transmitting and receiving cells to assess vertical jump and medicine ball to assess strength of the upper limbs.

    Measured: Change from week 9 neuromuscular performance at week 12

Secondary outcomes (6)
  1. Fibromyalgia impact questionnaire

    Questionnaire to ccess information on the functional capacity and health status of individuals with fibromyalgia. Composed of 20 questions. , the values vary from 0 to 100, in which the higher the value, the greater the impact of fibromyalgia.

    Measured: Baseline, week 9, week 12

  2. Pain intensity

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

    Measured: baseline and everyday until the week 12

  3. Anxiety

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

    Measured: baseline and everyday until the week 12

  4. Quality of sleep

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

    Measured: baseline and everyday until the week 12

  5. Fatigue

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

    Measured: baseline and everyday until the week 12

  6. Mood state

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

    Measured: baseline and everyday until the week 12

Questions about this trial

What is this clinical trial studying?

A study testing Strength exercise in people with Fibromyalgia, run by University of Beira Interior at 1 site in Brazil.

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 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?

Balance (time frame: Change from Baseline balance at week 9). The study lists 6 primary outcomes in all. 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 NCT05646641, 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 31 Dec 2025.
