Abstract

Background

Most studies of knee joint motion during gait in patients who experienced a stroke have focused on comparisons with healthy individuals. However, comparisons of patients with varying gait abilities have not been adequately performed. This study compared the kinematic parameters of the bilateral knee joints of patients who experienced a stroke. These patients were divided into those with fast gait speed and those with slow gait speed to determine any differences in motion.

Methods

Twenty patients who experienced a stroke were included in this study. The fast and slow gait speed groups both comprised 10 patients. Knee joint-related parameters were the timing and flexion angle at the start of the swing phase on both sides and timing and flexion angle at the peak knee joint flexion angle. The difference between timing during both phases and the difference between the knee joint flexion angle during both phases were calculated.

Findings

Significant differences in the timing and angle at the start of the swing phase, peak timing, and peak angle of the fast and slow groups were observed on the affected side (p < 0.05). Significant differences in the timing of the start of the swing phase, peak timing and difference between timing of the fast and slow groups were observed on the unaffected side (p < 0.05).

Interpretation

Clear differences in the kinematic characteristics of the knee joints on the affected and unaffected sides were observed in both groups. These valuable insights regarding knee joint motion may improve the gait speed of such patients.

中风患者摇摆阶段的膝关节运动学：高速和低速步行者的比较

背景：大多数关于中风患者步态中膝关节运动的研究都集中在与健康个体的比较上。然而，对不同步态能力的患者的比较尚未充分进行。本研究比较了中风患者双侧膝关节的运动学参数。这些患者被分为快步速组和慢步速组，以确定运动是否有差异。方法选取20例中风患者作为研究对象。快步速组和慢步速组各10名患者。膝关节相关参数为两侧摆动阶段开始时的时机和屈曲角度以及膝关节屈曲角度峰值时的时机和屈曲角度。计算了两阶段的时间差值和膝关节屈曲角度差值。结果：患侧快、慢两组摇摆期开始时间、角度、峰值时间、峰值角度差异有统计学意义（p < 0.05）。在未受影响的一侧，快、慢两组在摇摆相开始时间、峰值时间和时间上的差异有统计学意义（p < 0.05）。在两组中，观察到受影响侧和未受影响侧膝关节的运动学特征有明显差异。这些关于膝关节运动的有价值的见解可能会提高这类患者的步态速度。

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.
