Brief Summary
Evaluating laterality changes in different psychiatric and neurodevelopmental diseases has recently been one of the popular perspectives of laterality studies. There are studies reporting changes in functional and structural hemispheric asymmetries in some neurodevelopmental and psychiatric diseases, and thus relations with atypical lateralization patterns or handedness. There is no study in the literature evaluating brain lateralization or handedness in fibromyalgia. The aim of our study is to evaluate the relationship between handedness, which is an indicator of brain lateralization, and fibromyalgia disease severity and functional outcomes related to fibromyalgia in patients with fibromyalgia. This cross-sectional study included 40 fibromyalgia patients aged 20-50 years, meeting the American College of Rheumatology 2016 Fibromyalgia Diagnostic Criteria, and 40 healthy volunteers in the same age range as the control group. Information about the age, gender, height, weight, and comorbidities of the participants included in the study were recorded. In addition, information about the duration of fibromyalgia diagnosis and pharmacological and non-pharmacological treatments for fibromyalgia were also recorded in the patient group. Handgrip strengths with Jamar-type hand dynamometer, tip pinch strengths with pinch meter, and hand dexterities with the Nine-Hole Peg Test were evaluated for both hands of all participants. The Edinburgh Handedness Inventory, Beck Depression Inventory, and Beck Anxiety Inventory were administered to all participants. In addition, the American College of Rheumatology 2016 Fibromyalgia Diagnostic Criteria was questioned in the patient group, and the Revised Fibromyalgia Impact Questionnaire was applied.

Outcome Measures
Primary Outcomes (3)
The handgrip and tip pinch strengths
The handgrip strength and tip pinch strength of the participants were measured using the Jamar-type hand dynamometer and pinch meter available in our clinic. In the analysis, the average of the three measurements made with an interval of five minutes was taken as the basis for the analysis.
6 months
The Nine Hole Peg Test
This test was used to evaluate the hand dexterity of the participants. This test consists of a square area and nine holes in this area, nine cylinders suitable for these holes, and a storage box. Participants quickly took the nine cylinders from the storage box and placed them in the holes, and after placing all the cylinders, they put the cylinders back in the storage box one by one. The shorter test times were considered to indicate better hand dexterity.
6 months
The Edinburgh Handedness Inventory
It is a questionnaire developed by Oldfield in 1971 to evaluate handedness. This inventory questions individuals' hand use in 10 different activities of daily living (writing, drawing, throwing, using scissors, brushing teeth, using a knife, using a spoon, using a broom, lighting a match, opening a box). In the inventory, there are two boxes for each activity questioning the use of the right and left hand. Only the right or left hand is always used for the specified activity; if the other hand is not used at all, both boxes for the used hand are checked. Generally, if the right or left hand is used for the specified activity, one of the boxes for the used hand is checked. If the specified activity is performed using both hands, one of the boxes on both the right and the left is checked. Right, and left-hand scores are calculated by counting the boxes checked for right and left-hand use.

Interventions
The handgrip strength and tip pinch strength of the participants were measured using the Jamar-type hand dynamometer and pinch meter available in our clinic. The handgrip strengths were measured with shoulders in adduction and neutral rotation, elbows in 90 degrees flexion, and forearms and wrists in a neutral position, while the tip pinch strengths were measured by squeezing a pinch meter between the thumb and index finger. Participants took a deep breath and then applied gripping force with maximal force while exhaling. In the analysis, the average of the three measurements made with an interval of five minutes was taken as the basis for the analysis.
This test was used to evaluate the hand dexterity of the participants. This test consists of a square area and nine holes in this area, nine cylinders suitable for these holes, and a storage box. Participants quickly took the nine cylinders from the storage box and placed them in the holes, and after placing all the cylinders, they put the cylinders back in the storage box one by one. In the evaluation of the test, the time elapsed during these operations was measured in seconds with a chronometer, and shorter times were considered to indicate better hand dexterity.
