摘要

背景：对于能够独立行走（粗大运动功能分级系统（GMFCS）Ⅰ级或Ⅱ级）的脑瘫（CP）儿童和青少年来说，跑步是一项基本的运动技能，使他们能够玩耍并参与学校和社区活动。从逻辑上讲，跑步干预能使跑步目标顺利实现，从而改善跑步运动学，但这一点尚未得到证实：研究问题：低负荷负重跑步干预能否改善 CP 儿童跑步时的关节运动学？在为期 12 周的干预前后进行了三维步态分析。计算步态轮廓评分（GPS），并建立线性混合模型：本研究共纳入 36 名脑瘫儿童（对照组：男=10，女=8，GMFCS I=12，GMFCS II=6，平均年龄=12.7 岁；干预组：男=13，女=5，GMFCS I=12，GMFCS II=6，平均年龄=12.7 岁）。随访结果显示，GPS 在组间无明显差异。GPS随着速度的增加而增加（即跑步运动学变得更加不典型）：意义：低负荷负重运动干预对CP儿童的目标实现有显著效果，但对GPS测量的跑步运动学没有整体影响。未来的研究应根据GMFCS水平和分布（单侧CP与双侧CP）进行。

The effect of a low-load plyometric intervention on running kinematics in youth with cerebral palsy: A randomised controlled trial

Background

For children and adolescents with cerebral palsy (CP) who are independently ambulant (Gross Motor Function Classification System (GMFCS) I or II), running is a fundamental movement skill that enables them to play and engage in school and community activities. A running intervention which resulted in good running goal attainment should logically have improved running kinematics, however, this has not yet been established.

Research question

Does a low-load plyometric running intervention improve joint kinematics during running in children with CP?

Methods

Three-dimensional gait analysis was undertaken before and after a 12-week intervention. The Gait Profile Score (GPS) was calculated, and linear mixed models were developed.

Results

36 children with cerebral palsy (control group: male=10, female=8, GMFCS I=12, GMFCS II=6, mean age=12.7 years; intervention group: male=13, female=5, GMFCS I=12, GMFCS II=6, mean age=12.7 years) were included in this study. No significant between-group differences in GPS were found at follow-up. The GPS increased (i.e. running kinematics became more atypical) as speed increased.

Significance

A low-load plyometric intervention which resulted in significant goal attainment in children with CP had no overall effect on running kinematics as measured by the GPS. Future studies should be powered according to both GMFCS level and distribution (unilateral vs bilateral CP).

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
