摘要

背景：很少有研究评估全髋关节置换术后早期步态中的垂直地面反作用力、接触时间、接触面积和压力中心。本研究旨在调查这些参数是否在全髋关节置换术后的参与者中比健康对照组更明显。方法：我们纳入22例接受全髋关节置换术的女性受试者(年龄：68.9±7.2岁；体重指数22.9±2.6 kg/m2)和健康女性对照11例(年龄50.3±7.8岁；体重指数（19.4±1.7 kg/m2）为对照。采用测力板测量行走时的垂直地面反作用力、接触时间、接触面积和压力中心。使用单向方差分析或Kruskal-Wallis检验对受影响腿、未受影响腿和对照腿进行比较，并使用独立t检验或Mann-Whitney U检验进行额外比较。结果：患腿的第一个力峰值较低，到达第一个力峰值的时间和脚后跟接触时间较长，第二次力峰值的接触面积明显大于未受影响的腿或对照组的右腿。与对照组相比，全髋关节置换术组的这些参数明显更加不对称，在起始位置和压力中心长度上存在显著差异。解释：在全髋关节置换术队列中，步态中足底接触的加载时间、大小和形式比健康女性更不对称。全髋关节置换术后早期康复应解决这些不对称。

Symmetries of the vertical ground reaction force, contact time and area, and center of pressure during gait in female patients 3 weeks post-total hip arthroplasty

Background

Few studies have assessed vertical ground reaction force, contact time, contact area, and center of pressure during gait in the early phase post-total hip arthroplasty. This study aimed to investigate whether these parameters are more pronounced in participants post-total hip arthroplasty compared to healthy controls.

Methods

We included 22 female participants who underwent total hip arthroplasty (age, 68.9 ± 7.2 years; body mass index, 22.9 ± 2.6 kg/m²) and 11 healthy female controls (age, 50.3 ± 7.8 years; body mass index, 19.4 ± 1.7 kg/m²) as controls. Vertical ground reaction force, contact time, contact area, and center of pressure during gait were measured using a force plate. Comparisons between the affected, unaffected, and control legs were conducted using one-way analysis of variance or the Kruskal–Wallis test, with additional comparisons using independent t-tests or the Mann–Whitney U test.

Findings

The first peak force was lower, the time to the first peak force and heel contact time were longer, and the contact area at the second peak force was significantly larger in the affected leg than in the unaffected leg or the right leg of the controls. These parameters were significantly more asymmetrical in the total hip arthroplasty cohort compared to the controls, with significant differences in the starting position and center of pressure length.

Interpretation

The loading timing, magnitude, and form of plantar contact during gait were more asymmetrical in the total hip arthroplasty cohort than in healthy females. Early-phase rehabilitation post-total hip arthroplasty should address these asymmetries.

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.
