About the trial

What the trial wants to find out

The aim of the study is to investigate the relationship between central sensitization parameters and changes in static and dynamic balance in patients with fibromyalgia.

Read full original descriptionShow less

The main questions it aims to answer are:

* Do central sensitization parameters differ in patients with fibromyalgia compared to healthy individuals? * How is balance performance in these individuals compared to healthy controls? * Do central sensitization parameters affect static and dynamic balance in patients with fibromyalgia? * Do central sensitization parameters lead to quantitative changes in balance in patients with fibromyalgia?

The 2 groups in the trial

  • Group 1 (Healthy volunteers)

    Healthy volunteers without a diagnosis of Fibromyalgia Syndrome will be included in Group 1. (n=20)

    Treatment: Biodex Balance System, Pressure Pain Threshold (PPT) Measurement with Algometer, Conditioned Pain Modulation (CPM), Slowly Repeated Evoked Pain Assessment Protocol (SREP), Central Sensitization Inventory (CSI), Numeric Rating Scale (NRS), Revised Fibromyalgia Impact Questionnaire (FIQ), S-LANSS Pain Score (Self-administered Leeds Assessment of Neuropathic Symptoms and Signs), Tampa Kinesiophobia Scale (TKS), Hospital Anxiety and Depression Scale (HAD), SF-12 Health Survey (SF-12 Quality of Life Scale), Fatigue Severity Scale (FSS), and Timed Up and Go Test (TUG)

  • Group 2 (Patients with fibromyalgia syndrome)

    Patients diagnosed with Fibromyalgia Syndrome according to ACR 2016 criteria will be included in Group 2. (n=55)

    Treatment: Biodex Balance System, Pressure Pain Threshold (PPT) Measurement with Algometer, Conditioned Pain Modulation (CPM), Slowly Repeated Evoked Pain Assessment Protocol (SREP), Central Sensitization Inventory (CSI), Numeric Rating Scale (NRS), Revised Fibromyalgia Impact Questionnaire (FIQ), S-LANSS Pain Score (Self-administered Leeds Assessment of Neuropathic Symptoms and Signs), Tampa Kinesiophobia Scale (TKS), Hospital Anxiety and Depression Scale (HAD), SF-12 Health Survey (SF-12 Quality of Life Scale), Fatigue Severity Scale (FSS), and Timed Up and Go Test (TUG)

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
