About this study
Official title: Evaluation of Fingertip Precision Pinch Force During Carrying in Fibromyalgia Patients.
This study aims to evaluate the force used by fibromyalgia patients during a task compared to healthy volunteers and to evaluate its relationship with fatigue seen in these patients.
Read the detailed description
Fatigue is a common symptom in fibromyalgia patients and it is known that these patients have decreased muscle strength compared to healthy volunteers. The aim of this study was to evaluate whether the minimum force to be applied during carrying is different in fibromyalgia patients compared to healthy volunteers.

Questions about this trial
What is this clinical trial studying?
An observational study of Fibromyalgia and Force Measurement, run by Dilara Ekici Zincirci at 1 site in Turkey (Türkiye).
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 1 inclusion and 6 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 26 Jun 2025. 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 Turkey (Türkiye). 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?
minimum pinch force (time frame: November 2024- January 2025). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 26 Jun 2025.
