摘要

背景：根据先前报道的BC儿童的静态下肢关系，预计背背儿童（BC）和非背背儿童（NBC）的下肢运动学和时空差异。背着孩子在南非很常见，在西方人中也很流行。因此，确定背背对下肢发育和步态的潜在影响是很重要的。研究问题：BC是否影响儿童三平面瞬时下肢运动学和全步态周期的时空参数？静态胫骨扭转与下肢步态运动学之间是否存在关联？方法选择12例NBC患儿（年龄= 8.00 ± 0.95岁）和12例BC患儿（年龄= 8.08 ± 0.79岁）。使用八摄像头运动分析系统和Visual3D软件提取步态过程中髋关节、膝关节和踝关节的三平面运动学数据。测量所有静态胫骨扭转的角度。采用统计参数映射（SPM）比较步态周期中的关节运动学和整个步态周期中胫骨扭转的关联。结果spm显示BC和NBC参与者在52-66 %的步态周期和34-41 %的步态周期中髋关节运动学（平均差值= 2.49°，p = 0.016）和膝关节运动学（平均差值= 3.00°，p = 0.026）存在显著差异。速度、步幅、站立时间和步幅的时空差异不显著（p = 0.80,gHedges = 0.10）。BC患儿的膝关节（r = -0.44 ~ - 0.69,p = 0.041）和NBC患儿的踝关节（r = 0.74 ~ 0.75,p = 0.025）的静态胫骨扭转与关节运动学之间存在显著相关性。在背背儿童的摆动阶段，较大的胫骨内扭转与更多的脚趾内旋和膝关节内旋有关。BC和NBC儿童运动学的离散比较没有产生显著差异，而使用SPM观察到差异。观察到的差异可能具有有限的临床重要性，这意味着护理人员可以继续对他们的孩子进行BC检查。

Comparison of tri-planar lower-limb kinematics and the association with tibial torsion in back-carried children. A statistical parametric mapping approach

Background

Lower-limb kinematic and temporospatial differences between back-carried (BC) and non-back-carried (NBC) children are expected based on previous static lower-limb relationships reported in BC children. Back-carrying of children is common among South Africans and becoming popular among Westerners. Establishing the potential effects of back-carrying on lower-limb development and gait is therefore important.

Research question

Does BC influence the tri-planar instantaneous lower-limb kinematics and temporospatial parameters of the full gait cycle in children, and is there an association between static tibial torsion and the lower-limb gait kinematics?

Methods

Twelve NBC (age = 8.00 ± 0.95 years) and 12 BC (age = 8.08 ± 0.79 years) children were selected. Tri-planar kinematics of the hip, knee, and ankle were captured during gait using an eight-camera motion analysis system and Visual3D software to extract the kinematic data. All static tibial torsion were measured goniometrically. Statistical parametric mapping (SPM) was used to compare joint kinematics during the gait cycle and the association of tibial torsion throughout the gait cycle.

Results

SPM revealed significant differences between BC and NBC participants in hip kinematics (mean difference = 2.49°, p = 0.016) at 52–66 % of the gait cycle and knee joint kinematics (mean difference = 3.00°, p = 0.026) at 34–41 % of the gait cycle. Temporospatial differences were non-significant for speed, stride length, stance time, and stride width (p = 0.80, g_Hedges = 0.10). Significant correlations were evident between static tibial torsion and joint kinematics for the knee (r = -0.44 to −0.69, p = 0.041) for BC children and for the ankle (r = 0.74–0.75, p = 0.025) in NBC children. Larger internal tibial torsion is associated with more in-toeing and internal knee rotation during the swing phase in back-carried children.

Significance

A discrete comparison of kinematics in BC versus NBC children did not yield significant differences, while differences were observed using the SPM. The observed differences are likely of limited clinical importance, implying that caregivers can continue to BC their children.
