An observational study in Fibromyalgia and PCOS (Polycystic Ovary Syndrome) of Bilateral Ovaries, sponsored by Ufuk University. Not yet recruiting at 1 site in Turkey (Türkiye). Open to female participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-09-23.
Sponsored by Ufuk University · Observational
The primary objective was to determine the prevalence of fibromyalgia in women with PCOS and to examine the relationship between fibromyalgia and psychological status (depression and anxiety). Secondary objectives were to explore the potential link between fibromyalgia and insulin resistance, taking into account phenotypic differences. To assess the relationship between fibromyalgia severity and quality of life and pressure pain threshold measurements. To analyze the impact of pain and mood disorders on PCOS phenotypes and to demonstrate the role of insulin resistance in predicting fibromyalgia.
Participants will be women aged 18-40 diagnosed with PCOS according to the Rotterdam criteria, and a healthy control group of a similar age. When making a PCOS diagnosis, clinical (hirsutism, acne, menstrual irregularity), biochemical (free testosterone, DHEAS, androstenedione, etc.), and ultrasonographic (polycystic ovary morphology) findings will be evaluated. The control group will consist of healthy volunteers presenting with gynecological complaints other than PCOS and without chronic diseases.
Examination and Assessment Process Obstetrics and Gynecology Outpatient Clinic: PCOS diagnosis, demographic data, biochemical tests (glucose, insulin, HOMA-IR, etc.), and phenotyping.
Physical Therapy and Rehabilitation: Application of the 2016 ACR fibromyalgia criteria in a single-blind trial, including measurement of pressure pain threshold (algometer), fibromyalgia severity scale, and recording of Fibromyalgia Impact Questionnaire scores.
Psychological Assessment The HADS (Hospital Anxiety and Depression Scale) will be administered to assess depression and anxiety levels.
Scores obtained will be compared with fibromyalgia diagnosis and PCOS phenotypes to examine the influence of psychological factors on pain perception.
1,243 studies on the registry are indexed under Fibromyalgia; 256 are open to participants now.
This study's planned enrollment of 140 is above the median of 100 across 279 observational studies indexed under Fibromyalgia.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HADS (Hospital Anxiety and Depression Scale)
The HADS (Hospital Anxiety and Depression Scale) will be administered to determine depression and anxiety levels. The HADS consists of 14 questions that score both anxiety (HADS-A) and depression (HADS-D) symptoms on a scale of 0 to 3. The scores obtained will shed light on the participant's psychological state and allow for the psychological evaluation of the relationship between fibromyalgia and PCOS.
Time frame: 1 month
2016 ACR Fibromyalgia Criteria-The Widespread Pain Index (WPI)
The assessment of the WPI involves indicating persistent pain over the past seven days across five anatomical regions (upper left, upper right, lower left, lower right, axial) and 19 specific body areas (both jaws, shoulders, upper arms, lower arms, hips, upper legs, lower legs, neck, upper back, lower back, chest, and abdomen). Each region is assigned one point. The cumulative score varies from 0 to 19. 15 For a diagnosis of widespread pain, pain must be evident in a minimum of 4 out of 5 anatomical regions.
Time frame: 1 month
2016 ACR Fibromyalgia Criteria-Symptom Severity Scale (SSS)
The SSS evaluation comprises two components. In the initial section, patients evaluate the intensity of their fatigue, unrefreshing awakenings, and cognitive problems from the past week on a scale of 0 to 3. In the subsequent section, patients evaluate symptoms of headache, lower abdomen pain or cramping, and depression experienced over the preceding six months (0=none, 1=yes). The cumulative score varies from 0 to 12.
Time frame: 1 month
2016 ACR Fibromyalgia Criteria-The Fibromyalgia Severity Scale (FSS)
The Fibromyalgia Severity Scale (FSS) assessment involves the collection of WPI and SSS scores. The cumulative score varies between 12 and 31. A higher score signifies a greater disease severity. A total score exceeding 12 is required for a fibromyalgia diagnosis. A WPI of 7 or greater and an SSS score of 5 or above, or a WPI between 4 and 6 with an SSS score of 9 or above, indicate a diagnosis of fibromyalgia.
Time frame: 1 month
Fibromyalgia Impact Questionnaire Revised (FIQ-R)
It is a questionnaire designed to assess functional limitations and disabilities resulting from fibromyalgia. The questionnaire comprises a total of 21 questions divided into three sections: function, overall impact, and symptoms. Responses to each inquiry are indicated on a scale ranging from 0 to 10. The overall score is determined by summing the results: the score of the first section is divided by three, the score of the second section by one, and the score of the third section by two. Elevated scores signify a greater fibromyalgia-associated impairment.
Time frame: 1 month
Pressure Pain Threshold (BPT) Measurement (Algometer)
Pressure Pain Threshold (BPT) Measurement (Algometer): For objective pain assessment, a digital algometer will be used to measure the pressure pain threshold (the pressure level at which the patient first feels pain) at the most sensitive point on the upper trapezius muscle. The measurement will be repeated three times, and the average will be recorded.
Time frame: 1 month
VAS (Visual Analog Scale)
VAS (Visual Analog Scale): Participants will mark the intensity of their perceived pain on a 10-cm scale, rated from 0 (no pain) to 10 (unbearable pain). This method is a simple and effective way to measure a patient's subjective perception of pain.
