Brief summary
The study aims to determine the posture, balance and gait disorders objectively in patients with fibromyalgia (FM) and to investigate their relationships with disease-related parameters.
Detailed description
After being informed about study and potential risks, all participants giving written informed consent will undergo screening period determine eligibility for study entry. The participants who met the eligibility recruitments will get into the assessment. The study will include 100 participants aged between 18-65 years and without any disease or orthopedic disorder that can cause posture, balance and gait disorders: 50 female patients who met the ACR (American College of Rheumatology) 2016 FM diagnostic criteria and 50 pain-free females. Researcher will record sociodemographic data of all participants and disease duration of patients with FM. The researcher will evaluate disease activity by Fibromyalgia Impact Questionnaire, sleep quality by Pittsburgh Sleep Quality Index and fatigue severity by Fatigue Severity Scale in FM group. In both groups the researcher will use; DIERS formetric 3D/4D video-rasterstereography (Diers International GmbH, Schlangenbad, Germany) device for the posture analyze, HUR SmartBalance BTG4 system (Hur Labs, Kokkola, Finland) for postural balance control and limits of stability measurements, Zebris FDM type 3 (Zebris Medical GmbH, Germany) gait analysis system for measuring spatio-temporal gait parameters.

Inclusion criteria
* Being diagnosed with Fibromyalgia according to ACR 2016 diagnostic criteria * Signing written informed consent to participate in the study
Exclusion criteria
* Rheumatological, neurological and/or psychiatric diseases that may cause balance and gait disorders (cerebrovascular accident sequelae, Parkinson's, myasthenia gravis, polyneuropathy, rheumatoid arthritis, ankylosing spondylitis, major depression) * Other diseases that cause balance and other gait disorders (history of major trauma to the lower extremity, and/or orthosis users, those who have had spinal and/or lower extremity surgery) * Orthopedic disorders that may cause limitation in joint range of motion and/or loss of motor muscle strength * Those who cannot take commands due to cognitive dysfunction * Vestibular and/or cerebellar disorders * Abnormal ophthalmic/optometric disorder (vision disorders) * Pregnancy * Serious cardiac disease, malignancy and renal failure
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Posture | Baseline | Posture analysis will be evaluated by DIERS Formetric 4D (Diers International GmbH, Schlangenbad, Germany). Participants will be positioned two meters away from the projector. The slide projector projects a series of parallel light strips on the back of the participant. The back's surface will be captured on camera converted to digital data, and displayed in three dimensions. Every scan will record 12 images over 6 seconds (2Hz) and the manufacturer's recommendations will be followed for processing. Spinal reference points, measures of the spinal curves, distance and localization, imbalances of the trunk and pelvis and spinal deviation will be measured. Spine parameters are expressed in millimeters, percentages or degrees depending on the specific parameter. |
| Balance | Baseline | The static and dynamic postural control will be measured by HUR SmartBalance BTG4 system (Hur Labs, Tampere, Finland). Participants will be asked to stand barefoot on the balance platform and to stand as quietly as possible, looking forward, during the measurement. While the stable surface is the platform's own floor, the unstable surface is the foam cushion provided by the manufacturer with the device. Data will be collected for 30 seconds. The following parameters will be calculated from the center of pressure (CoP) displacement time series for static postural control: sway area, velocity, Romberg. The limits of stability (LOS) was used to evaluate the dynamic postural control. The participants were asked to tilt their bodies forward, backward, leftward, and rightward for 8 seconds in each direction on the same platform. |
| Gait | Baseline | Spatio-temporal gait analysis was performed by Zebris FDM type 3 (Zebris Medical GmbH, Germany) gait analysis system. The system consists of a 3 meters long main platform which contains sensors for measuring the force distributions and a 1 meters long maneuvering platforms that located at the beginning and end of the main platform. Participants will be asked to walk barefoot on the platform. Each participant will walk at their comfortable speed for 2 minutes continuously going from one end to the other along a 5-m walkway in a quiet, well-lit room. The main platform was located in the middle of the system in order to avoid the unstable walking periods on turns. The data were analyzed and recorded on the computer. Foot rotation, stride length, step width, double limb support phase, cadance will be measured. Gait parameters are expressed in centimeters, percentages or degrees depending on the specific parameter. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fibromyalgia Impact Questionnaire (FIQ) | Baseline | In FM group; Fibromyalgia Impact Questionnaire (FIQ) will be used to measure the impact of FM on patient's physical function, health status and the severity of disease activity. FIQ is scored from 0-100. Higher scores indicate increased severity of the impact of FM. |
| Pittsburg Sleep Quality Index (PSQI) | Baseline | Pittsburg Sleep Quality Index (PSQI) will be used to evaluate sleep quality and the presence of sleep disturbance. The total score consists of 7 components. These components consist of a single question or a combination of several questions. Each question is evaluated on a 0-3 point scale. The total score is between 0-21. A high score indicates poor sleep quality. |
| Fatigue Severity Scale (FSS) | Baseline | Fatigue Severity Scale (FSS) will be used to assess fatigue level. The scale consists of 9 questions. Participants are questioned about the level of fatigue in the last week. The questions are scored between 1-7. 1 point: strongly disagree and 7 points: strongly agree, scaled as a Likert-type scale where the degree of agreement increases as the points increase. The highest possible score is 7. Scores of 4 and above indicate pathological fatigue. |
