The goal of this observational study is to determine whether there is a decrease in muscle mass and the relationship between lower extremity skeletal muscle mass, muscle strength and disease activity in Ankylosing spondylitis. The main questions it aims to answer are: * Is there a relationship between the muscle thickness and pennation angle of the quadriceps, Gastrocnemius medialis and lateralis, Vastus medialis and lateralis and tibialis anterior muscles with disease activity and muscle strength? * Are there any differences in the results of morphological parameters of lower extremity muscles between Ankylosing spondylitis and voluntary participants? Researchers will compare voluntary participants to see if any difference in lower muscle morphological parameters.
Ankylosing spondylitis (AS) Ankylosing spondylitis (AS) is a systemic inflammatory rheumatic disease that can cause characteristic inflammatory low back pain and structural and functional disorders by affecting the axial and peripheral skeleton. Functional impairment increases with age, disease duration, and severity of symptoms. It has been shown that there is a significant relationship between dysfunction and activity limitation in AS patients. Recent studies have reported that both sarcopenia and decreased muscle strength occur in patients with chronic inflammatory diseases such as rheumatoid arthritis3. There are concerns that sarcopenia may affect exercise tolerance, activities of daily living, and ultimately have a negative impact on cardiovascular fitness and physical and emotional well-being. Given the risk of chronic inflammation and reduced physical activity, patients are also at risk of accelerated muscle wasting. In chronic diseases, loss of muscle mass, often referred to as cachexia, is a relevant systemic complication that leads to decreased muscle strength and endurance, reduced physical activity and fitness. However, there is no study reporting variation in lower extremity information, muscle development, morphological effects measured by ultrasound, muscle strength and disease intensity in AS patients. Therefore, this study was conducted to determine whether there is a decrease in muscle according to the wide general spread in AS patients and to strengthen the detachable lower extremity structure with AS, muscle strength and possible presence. The relationship between strength, power and mobility of skeletal muscles was also evaluated. Although muscle loss was not morphologically evident in previous ultrasounds, it has not been investigated whether this leads to loss of muscle strength.

Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)
It evaluates disease-specific symptoms such as fatigue, spinal and peripheral joint pain, swelling and morning stiffness and is interpreted on a score ranging from 0 to 10. Each question is scored on a scale of 0 to 10. Aside from the last question, 0 indicates none and 10 indicate very severe. For the last question, 0 is 0 hours, 5 is one hour, and 10 is two or more hours. To calculate the BASDAI score, the formula is: BASDAI = ((Q1 + Q2 + Q3 + Q4) + ((Q5 + Q6) / 2)) / 5
Time frame: 1 Day
Bath Ankylosing Spondylitis Functional Index (BASFI)
It is an index that is fast and easy to apply, sensitive to changes and reliable, developed for determining and monitoring the functional status of patients with AS. It consists of 10 questions that evaluate patients' abilities to bend, reach, stand, change positions, climb stairs, and cope with activities of daily living. For each question, the final score is obtained by dividing the total score by 10 using the visual analogue scale (VAS) in the range of 0-10 cm. A higher score indicates a higher degree of functional limitations.
Time frame: 1 Day
Bath Ankylosing Spondylitis Metrology Index (BASMI)
BASMI consists of five clinical measurements: cervical rotation, tragus wall distance, lumbar flexion, trunk lateral flexion, and intermalleolar distance. It was first developed as a two-point scale in 1994 and was later adapted to a 10-point score. The 10-point BASMI scale was used in our study.The higher the BASMI score the more severe the patient's limitation of movement due to their Ankylosing Spondylitis.
Time frame: 1 Day
Rivermead Mobility Index
It is a one-dimensional index that focuses on measuring mobility status and includes basic mobility activities. It includes a series of hierarchical activities, from turning over in bed to running, consisting of 14 questions and one observation that fit the Guttman Scale. RMI was mainly developed for the purpose of evaluating the results of physiotherapy interventions after head trauma or stroke, and it is reported that it can be used in hospitals, outpatient clinics or home environments without requiring expertise. Self-reporting is essential in answering questions. Only the 5th item is observed and evaluated by the interviewer. 1 point is given for each "yes" answer and a range of 0-15 points can be received. A score of 15 points indicates that there is no problem in mobility, and a score of 14 points and below indicates that there is a mobility problem.
