Examining the Prevalence of Lower Body Disorders Among Male Lower-Secondary Education Students in Kermanshah

Skeletal disorders affect the individual’s physical fitness and outcome in everyday life and athletic activities. The study examined the prevalence of different disorders of lower body among male students of lower-secondary education. A sample of 390 male lower-secondary education students in Kermanshah was selected using cluster sampling. The variables examined were muscle length shortening, supinated foot, hallux valgus, pes cavus, flat foot, genu varum, knock knees, genu recurvatum, and Knee flextion. The mean and standard deviation of the age of the students were 13.70.5 years, 40.783.05 kg for weight, and 150.016.6 cm for height. Data were collected through physical examinations of the lower limb using New York test, padscope, caliper and determination of body type using Sheldon’s method. Descriptive statistics were used for data analysis. Only 18.93% of the students examined had normal condition, whereas 81.07% of them had one of the abnormalities in the lower limbs. Knee flexion with 3.85% and supinated leg with 4.1% had the lowest and hallux valgus and genu varum with 53.85% and 38.72%, respectively, had the highest prevalence. Regarding body types, 61.8% of the students had ectomorph, 21.79% endomorph,
and 16.41% mesomorph body types. The resultsshowedthat largerandmoremobile joints have less resistanceandmorevulnerabilitycomparedto smaller joints, whose motion range is limited by more muscles and strong ligaments. The lowest incidence rates of abnormalities were related to congenital abnormalities and abnormalities with high prevalence rates, mainly due to the lack of attention to proper shoes and the activity form of the organs involved with large joints.
