Asymmetry in Muscle Strength, Dynamic Balance, and Range of Motion in Adult Symptomatic Hip Dysplasia

Hip dysplasia (HD) is a typical developmental abnormality of the hip joint, and discomfort often found in adulthood. This study compared patients with symptomatic HD muscle strength, dynamic balance, range motion (ROM) healthy individuals. Patients included those who complained unilateral pain although lateral center edge angle (LCEA) exhibited bilateral abnormality. Participants (n = 95; men: 46, women: 49) were divided into asymptomatic sides, group without history joint disease 70; 30, 40) was compared. flexion, extension, abduction, adduction performed at an angular velocity 30°/s using isokinetic strength test device. The Y-balance conducted to measure ROM measured electronic goniometer evaluate adduction, internal external rotations. In addition, visual analog scale (VAS) groin outcome (HAGOS), subjective evaluation evaluated. (flexion, rotation, rotation) significantly decreased sides men women side, abduction also lower on sides. Although LCEA side than that group, there no significant differences VAS, ROM, extension conclusion, mostly bilateral, decrease strength; however, function relatively close normal.
