16 sessions, approximately 40 minutes each, will be administered twice a week for eight weeks by a physical therapist via video chat programs such as Zoom or WhatsApp. Kinesthetic brain exercises consist of three phases: a warm-up phase, an exercise phase, and a cool-down phase. The warm-up and cool-down phases consist of hand-eye coordination and relaxation exercises. The exercise phase consists of independent and dependent movements, as well as a combination of both.

It is frequently preferred because it is an easy and understandable scale. Participants are asked to mark the appropriate location for their pain intensity on a 10-cm horizontal line, with the beginning representing no pain and the end representing unbearable pain. Pain ranges are as follows: <3 indicates mild pain, 3-6 indicates moderate pain, and >6 indicates severe pain. Pain will also be assessed in four different situations: night pain, daytime pain, pain at rest, and activity pain.

The Pain Catastrophizing Scale is a self-administered questionnaire used to assess patients' thoughts and feelings about pain. Developed by Sullivan and colleagues in 1995, it is a reliable and valid questionnaire for Turkish that assesses specific variables such as severe pain, disability, and emotional disturbance following trauma or tissue damage. It consists of subscales for "helplessness" (inability to cope effectively with pain), "magnification" (displeasure caused by excessive focus on the negative consequences of pain), and "rumination" (inability to inhibit pain-related thoughts). It consists of 13 items and is scored from 0 to 4. It has a total of 52 points

Fatigue severity will be assessed using the Visual Analog Scale (VAS). It is frequently preferred because it is an easy and understandable scale. The beginning indicates no fatigue, and the end indicates extreme fatigue. To measure severity, a ruler will be used to measure the severity from the beginning of the line to the point marked by the participant and recorded

General fatigue, physical fatigue, mental fatigue, decreased motivation, and decreased activity. It has been used in various descriptive and experimental studies of many different diseases, including fibromyalgia. When completing the scale, participants are asked to select the rating closest to their level, from "no" to "yes" to "very true" out of 5. It consists of 20 questions. A high score indicates severe fatigue

It is a self-reported questionnaire that measures functional capacity and disease severity in patients with fibromyalgia. It is an easy and short-term questionnaire. It consists of 21 questions in three sections covering function, global impact, and symptoms. It concerns experiences over the past 7 days and is scored using an 11-point numerical rating scale. It consists of a total score for the function domain (range 0 to 90, divided by 3), a global impact score (range 0 to 20), and a symptoms domain score (range 0 to 100, divided by 2)

It is a reliable test frequently used to assess agility, dynamic balance, and functional mobility in individuals with fibromyalgia This test begins with the patient sitting in a chair with a backrest. The patient stands up from the chair, walks to a marker 3 meters away, and records the time they return to their seat. It will be administered three times, and the best value will be recorded

The participant will be positioned with their back supported, with their knees at 90 degrees and their torso at 60 degrees, their back straight, and their hands crossed on opposite shoulders. The physiotherapist will stabilize the feet and ask the participant to maintain this position as much as possible, removing the back support. The test will be terminated when the trunk angle is observed to disappear, and the elapsed time in seconds will be recorded.

The test begins when the subject, lying face down on a stretcher, with ankles and knees fixed on the stretcher, the trunk hanging from the stretcher with the spina iliaca anterior superior (SIAS) positioned over the edge of the stretcher, and the hands crossed in front of the stretcher, holding the shoulders, reaches a horizontal position. The time the subject maintains this position is recorded in seconds

The test will begin in a side-lying position. The participant will be asked to position their knees straight, their feet in a tandem stance, with the front foot on top, supporting their body with their bottom elbow and placing their top elbow on the opposite shoulder. They will be instructed to use only three points of support (elbows and feet) when lifting their hips off the mat. The test will end when the hips approach the mat or when support is gained from another location, and the elapsed time will be recorded

To evaluate the plank test, the time spent in push-up position on the floor mat, with the toes fixed on the floor mat, elbows flexed, touching the floor mat and hips up, without changing the position, will be recorded in seconds

The Cognitive Exercise Therapy Approach-Biopsychosocial Scale, which Zahid and Ünal developed in 2018 and has proven valid and reliable in individuals with fibromyalgia, will be used. This 30-item scale assesses the biopsychosocial processes associated with the disease. A 5-point Likert-type score is used for scoring the scale. A total score is obtained by scoring items as follows: No never = 0, Yes rarely = 1, Yes sometimes = 2, Yes often = 3, and Yes always = 4. A higher score indicates a lower biopsychosocial status

The Short Form-36 Quality of Life scale, consisting of 36 questions and will be used to assess participants' quality of life. This questionnaire examines eight dimensions of health with 36 items: social function, physical function, physical role difficulty, energy, mental health, emotional role difficulty, general health perception, and pain. In the absence of any limitations or barriers, the maximum possible score is 100. Each dimension is assessed independently, with a higher score indicating a higher quality of life for that dimension
