摘要

背景:在临床步态分析中,回归方程被广泛用于确定髋关节中心的位置。Hara等人的方程式需要对腿长进行单一的人体测量,从而便于在临床环境中实施。本研究将Hara等人的回归方程与Harrington等人及Davis等人的常用方程进行对比,评估其在脑瘫儿童临床步态分析中的应用。方法对30例脑瘫患儿(女性13例,年龄5 ~ 16岁)的髋关节中心位置进行回顾性步态分析。进一步比较了这些模型的髋关节和膝关节的步态运动学。结果:Hara髋关节中心的位置在其他两种模型之间确定:前1 cm和内侧,与Harrington模型的高度几乎相同。步态运动学反映了髋关节中心的位置,将Hara模型的曲线置于其他模型之间。Hara和其他模型在所有运动平面上的均方根差都在2.6度以内。Hara等人的回归方程显示了髋关节中心位置和步态运动学与其他常见方程的相似性。Hara模型简单,似乎不太容易受到与软组织相关的错误的影响,可能是脑瘫儿童临床步态分析的一个很好的选择。

Comparison of the Hara, Harrington, and Davis hip joint center regression equations for gait analysis in children with cerebral palsy

Background

Regression equations have been widely accepted in defining the location of the hip joint center in clinical gait analysis. Equations by Hara et al. require a single anthropometric measurement of leg length, allowing easy implementation in a clinical setting. This study evaluated the regression equations by Hara et al. in comparison to common equations by Harrington et al. and Davis et al. for clinical gait analysis in children with cerebral palsy.

Methods

The location of the hip joint centers was defined by each of the aforementioned three models and compared for retrospective gait analysis data of 30 children with cerebral palsy (13 females, age 5–16 years). Gait kinematics at the hip and knee across those models were further compared.

Findings

The location of the Hara hip joint center was defined in between the other two models: ∼1 cm anterior and medial with almost the same height as Harrington's model. Gait kinematics reflected the location of the hip joint centers, placing the curves from the Hara model in between the others. The root mean square differences between the Hara and the other models were within 2.6 degrees in all planes of motion.

Interpretation

The regression equations by Hara et al. demonstrated similarity in the location of the hip joint center and gait kinematics to other common equations. The Hara model is simple, appears less susceptible to errors associated with soft tissue, and might be a good alternative option for clinical gait analysis in children with cerebral palsy.

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.
