摘要

目的:确定在行走过程中施加持续的躯干侧向支撑力是否能改善躯干姿势控制并提高脊髓灰质炎患儿的步态表现:19名患有痉挛性脊柱炎的儿童(8名男孩,平均年龄(10.6 ± 3.4)岁)参加了本研究。其中 14 名儿童接受了以下测试:1)在跑步机上无外力行走 1 分钟(基线);2)躯干侧向支撑外力行走 7 分钟(适应);3)无外力行走 1 分钟(适应后)。地面行走前/后跑步机行走。其中五人进行了类似的测试,但没有躯干支撑力(即对照组):结果:与基线相比,实验组的参与者在适应后期腹直肌的步态相位依赖性肌肉激活增强(P = 0.005),在适应后期仍保持这种激活(P = 0.036);在适应后期,躯干斜角峰值的变异性降低(P = 0.023);在跑步机行走后,地面行走速度增加(P = 0.032)。对照组的参与者在跑步机和地面行走过程中的运动学和肌电图变化不大。这些结果表明,在行走过程中施加持续的躯干侧向支撑很可能会诱导CP患儿学习改善躯干姿势控制,这可能会部分转移到地面行走,尽管由于对照组样本量较小,我们还没有得出确切的结论。

Motor adaptation to continuous lateral trunk support force during walking improves trunk postural control and walking in children with cerebral palsy: A pilot study

Purpose

To determine whether the application of continuous lateral trunk support forces during walking would improve trunk postural control and improve gait performance in children with CP.

Materials and methods

Nineteen children with spastic CP participated in this study (8 boys; mean age 10.6 ± 3.4 years old). Fourteen of them were tested in the following sessions: 1) walking on a treadmill without force for 1-min (baseline), 2) with lateral trunk support force for 7-min (adaptation), and 3) without force for 1-min (post-adaptation). Overground walking pre/post treadmill walking. Five of them were tested using a similar protocol but without trunk support force (i.e., control).

Results

Participants from the experimental group showed enhancement in gait phase dependent muscle activation of rectus abdominis in late adaptation period compared to baseline (P = 0.005), which was retained during the post-adaptation period (P = 0.036), reduced variability of the peak trunk oblique angle during the late post-adaptation period (P = 0.023), and increased overground walking speed after treadmill walking (P = 0.032). Participants from the control group showed modest changes in kinematics and EMG during treadmill and overground walking performance. These results suggest that applying continuous lateral trunk support during walking is likely to induce learning of improved trunk postural control in children with CP, which may partially transfer to overground walking, although we do not have a firm conclusion due to the small sample size in the control group.

期刊介绍: Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
