The participants will be selected through inclusion and exclusion criteria. The research objectives will be explained to the participants. The participant will be included in the study with the written informed consent form. The aim of the study is to determine the prevalence of possible generalized joint hypermobility syndrome based on Beighton’s approach and factors associated with joint hypermobility among school children. During this study collects students name, age , gender, place as a demographic data . Personal characteristics will be measured and recorded, including height in centimeters, weight in kilos, sex, and age in years. The gold standard method (in bare feet; measured to the closest one centimeter and 100 grams, respectively) was used to measure weight and height. Using a metric method, weight (in kilograms) divided by height (in meters squared) was used to calculate the body mass index (BMI). Children were categorized as underweight (BMI < 18.5), ideal weight (BMI 18.5–24.9), overweight (BMI 25–29.9), or obese (BMI > 30). The degree of joint hypermobility will be scored by using the Beighton scoring system. The five clinical tests that make up the screening criteria were given a score of 0 or 1 according to the subject’s performance on them. After adding together all of the test results, the total range from 0 to 9.
