OBJECTIVE
The purpose of this study was to assess the influence of trunk rotation (TR) on postural sway and spatial-temporal parameters of gait in children and early adolescents screened at school for the presence of scoliosis.
METHODS
Two hundred and fifty-five individuals aged 9-14 (141 boys, 114 girls) underwent trunk rotation (TR) assessment by means of angle of trunk rotation (ATR) measurements performed with Bunnell's scoliometer. Participants with ATR ≥ 5° formed the TR group whose data were compared with those of a control group (CON) composed of individuals with ATR < 5° matched for age and anthropometric features. Postural sway was calculated on the basis of center of pressure (COP) time series acquired using a pressure plate. Spatial-temporal parameters of gait were derived from trunk accelerations collected by a single inertial sensor located in the low-back region.
RESULTS
Sway area, sway path, COP velocities in medio-lateral (ML) and antero-posterior (AP) directions and COP displacements in ML direction were found significantly higher in girls with TR, while no differences between the TR and CON groups were detected in boys. Both boys and girls with TR exhibited gait patterns similar to those of their CON schoolmates.
CONCLUSIONS
These findings suggest that even mild levels of TR may influence balance of female children and early adolescents screened for scoliosis, and thus early interventions including selective and task-oriented exercises appear advisable. In contrast, TR does not appear to influence gait, but further investigations are required to clarify whether different ATR cut-offs may reveal alterations of spatial-temporal parameters.
目的
本研究旨在评估躯干旋转（TR）对在校筛查脊柱侧弯的儿童和青少年的姿势摆动和步态时空参数的影响。
方法
255 名 9-14 岁（141 名男孩，114 名女孩）个体接受了躯干旋转（TR）评估，方法是使用 Bunnell 脊柱侧凸计测量躯干旋转角度（ATR）。ATR≥5°的个体形成 TR 组，将其数据与 ATR＜5°的对照组（CON）个体进行比较，CON 组个体的年龄和人体测量特征相匹配。基于压力板采集的中心压力（COP）时间序列计算姿势摆动。从位于下背部区域的单个惯性传感器采集的躯干加速度中得出步态时空参数。
结果
TR 女孩的摆动面积、摆动路径、COP 在中-侧（ML）和前-后（AP）方向上的速度以及 COP 在 ML 方向上的位移明显更高，而 TR 男孩与 CON 组之间无差异。TR 男孩和女孩的步态模式与他们的 CON 同学相似。
结论
这些发现表明，即使是轻度的 TR 也可能影响筛查脊柱侧弯的女性儿童和青少年的平衡，因此早期干预包括选择性和任务导向性锻炼似乎是合理的。相比之下，TR 似乎不会影响步态，但需要进一步研究以明确不同的 ATR 截止值是否可能揭示时空参数的改变。
