Comparison of Isometric Trunk Rotational Strength of Adolescents with Idiopathic Scoliosis to Healthy Adolescents

摘要

Trunk rotational strength asymmetry has been suggested in adolescents with idiopathic scoliosis (IS), but is unconfirmed. The sitting isometric trunk rotational strength, at neutral and 18 deg or 36 deg of right or left pre-rotation, of a group of healthy adolescent females (CG), n=12, is compared with a group of female adolescents with IS (ISG), n= 14. Torque values were normalized to lean body weight. There is a significant weakness when rotating towards the concavity found in patients with AIS at the 36 lo (p 0.07 marginal), 18 lo (p< 0.03) and neutral positions (p< 0.02), with no side strength asymmetry found in a cohort of healthy adolescents without AIS.
