摘要

背景单侧和双侧脑瘫患儿的步态运动学参数必须分别用具有良好心理计量学特性的统计指标来描述。本研究的目的是使用步态轮廓评分和步态变量评分对这两种形式的脑瘫进行比较。方法通过步态分析回顾性地计算出 47 名脑瘫儿童的步态轮廓评分，这些儿童被划分为粗大运动功能分级系统 I-III 级。统计分析用于比较：(1) I 级和 II 级之间的步态轮廓得分；(2) 单侧（28 人）和双侧（16 人）患儿的步态轮廓和变量得分，以及各亚组患儿双侧肢体之间的差异（显著性水平为 0.05）。两个亚组之间（p = 0.72）或双侧患儿双侧肢体之间（p = 0.85）的步态剖面得分无明显差异。单侧患儿瘫痪肢体的步态曲线得分明显高于非瘫痪肢体（p <0.005）。步态轮廓评分可区分单侧患儿瘫痪肢体和非瘫痪肢体的运动步态参数改变。步态变量评分有助于定位最大的运动障碍。

Quantification of gait impairment using the gait profile and variable score in children with cerebral palsy

Background

gait kinematic parameters of children with unilateral and bilateral cerebral palsy must be characterized separately by a statistical index with promising psychometric properties. The objective of this study was to compare both forms of cerebral palsy using the gait profile score and gait variable score.

Methods

Gait profile score of 47 children with cerebral palsy classified with a Gross Motor Function Classification System level I-III were retrospectively calculated from gait analysis. Statistical analysis were used to compare (1) gait profile score between level I and II, (2) gait profile and variable score between children with unilateral (n = 28) and bilateral (n = 16) forms as well as their difference between both limbs for each subgroup (significance level of 0.05).

Findings

The gait profile score was significantly different between level I and II (p ≤ 0.021). No significant difference was found for gait profile score between both subgroups (p = 0.72) or between both limbs of children with bilateral form (p = 0.85). The gait profile score was significantly higher for the paretic compared to the non-paretic limb of children with unilateral form (p < 0.005). Significant differences were found for some gait variable score between subgroups (p < 0.05).

Interpretation

The gait profile score can distinguish altered kinematic gait parameters in paretic from non-paretic limb in children with unilateral form. The gait variable score helps to localize the largest kinematic impairment.

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
