Hip Joint and Center of Gravity Kinematics in Gait Cycle of Young Adults With Moderate Idiopathic Scoliosis. A Controlled Study Introduction: Scoliosis influences the body and the pelvic region, a major determinant of gait. The effect on pelvic locomotion throughout the gait cycle of this entity is of major interesting. Purpose: To study the hip joint and center of gravity (CoG) locomotion in young adults with Moderate Idiopathic Scoliosis (MIS) compared to healthy population during the gait cycle. Aim of the study was also the differences in-between lower extremities of scoliosis patients. Methods: A cohort of twenty young adults (group A) having MIS and a control group (B) of fifteen healthy individuals were submitted in 3D gait analysis with direct linear transformation method. The parameters examined were concerning the displacement of the hip joint (greater trochanter) and the CoG on x, y and z axes. Additionally, the gait cycle duration was examined. Results: Mid leg length discrepancy (1.2 cm ± 0.2, C.I 95%) was evident in scoliosis patients. Regarding side to side comparison of the lower extremities in group A the following outcomes were identified: Hip and CoG had increased sagittal (forward/backward) displacement on the ipsilateral side (to scoliosis curve) compared to the controlateral side, p < 0.05. When comparing group A to group B the following differences were found (p < 0.05): (a) gait cycle in group A had increased duration compared to group B (an average from both extremities), (b) the hip in the ipsilateral side demonstrated increased frontal displacement (medial/lateral), (c) the hip in the controlateral side had increased frontal displacement and decreased sagittal displacement and (d) the CoG in the controlateral side had decreased sagittal displacement. Discussion: Scoliosis patients presented asymmetries in-between sides of the body regarding hip and CoG displacement at the sagittal axis. Produced higher lateral sway area and controlateral reduced sagittal motion than normal subjects. The gait cycle had increased duration compared to healthy people. The kinematic analysis combined to the clinical examination can create a basis for conservative intervention as well as further studies on biomechanics of MIS. Kinematika těžiště kyčelního koubu při chůzi mladých dospělých se střední idiopatickou skoliózou. Řízená studie Skolióza ovlivňuje tělo a pánevní oblast. Tato studie zkoumá pohyb kyčelního kloubu a těžiště (CoG) subjektů se střední idiopatické skoliózou (MIS) ve srovnání se zdravou populací během cyklu chůze. Cílem této studie bylo také popsat rozdíly mezi dolními končetinami skoliotických pacientů. 20 mladých dospělých S (sk. A) s MIS a 15 členná kontrolní skupina (B) podstoupila 3D analýzu chůze s metodou přímé lineární transformace. Sledovanými parametry byly: změna umístění kyčelního kloubu (trochanter maj.) a těžiště na osách x, y a z; délka cyklu chůze. U pacientů se skoliózou byl patrný rozdíl délky DK (1.2 cm ± 0.2, C.I. 95 %). Při stranovém porovnání DK sk. A byl zjištěn rozdíl vychýlení kyčle a CoG v sagitální rovině na straně skoliózy (ipsilaterální) a na straně protější (kontralaterální). Při porovnání skupin A a B byly zjištěny následující rozdíly (p < 0.05): (a) cyklus chůze trval ve sk. A déle než ve sk. B, (b) kyčel na kontralaterální straně měla vyšší vychýlení v rovině frontální a nižší v rovině sagitální, (c) těžiště na kontralaterální mělo nižší sagitální vychýlení.
