摘要

步态的变化与几个因素有关，包括年龄、性别和疾病的存在。最近开发的一种系统可以使用鞋内运动传感器和智能手机应用程序方便地测量步态。在这里，该系统被用于测量40名健康成年人和45名骨科疾病患者的7项步态参数。方法对健康志愿者进行为期1个月的步态监测。对患有膝关节或脊柱疾病的患者在手术前和手术后一年进行监测，并在术前和术后的四个时间点在医院进行监测，以监测步态的变化。在健康志愿者中评估参与者特征与步态之间的关系，并描述患者围手术期步态的变化。在健康的志愿者中，80多岁的人与40多岁的人相比，步态状况更差，比如走路速度更慢，步幅更短。此外，身高越高，步幅越长。在患有膝关节疾病的患者中，许多步态参数从术前到术后一个月恶化，然后在术后一年内趋于改善。相比之下，脊柱疾病患者即使在术后一个月也表现出改善，并持续改善至术后三个月。在日常生活中测量是可行的，并且被认为可以准确地反映每个参与者的步态。需要进一步的研究来调查步态参数和健康结果之间的关系。

Measurement of gait by an in-shoe motion sensor system: feasibility and potential application in healthy adults and patients with orthopedic diseases

Background

Gait varies in accordance with several factors, including age, gender, and the presence of disease. A recently developed system allows the convenient measurement of gait using in-shoe motion sensors and a smartphone application. Here, this system was used to measure seven gait parameters in 40 healthy adults and 45 patients with orthopedic disorders.

Methods

For the healthy volunteers, gait monitoring was performed for one month. This monitoring was also performed at home before and one year after surgery in patients with knee or spine disorders, and at hospital at four time points before and after surgery to monitor changes in gait. The relationship between participant characteristics and gait was assessed among the healthy volunteers, and change of gait in the perioperative period was described among the patients.

Findings

In the healthy volunteers, being in one's 80s was significantly related with worse gait conditions, such as slower walking speed and shorter stride length, than being in one's 40s. Also, higher height was associated with longer stride length. In the patients with knee disorders, many gait parameters worsened from before to one month after surgery, and then tended to improve up to one year post-surgery. In contrast, patients with spinal disorders showed improvement even at one month post-surgery, with continued improvement up to three months post-surgery.

Interpretation

Measurement in daily life was feasible, and thought to accurately reflect the gait of each participant. Further studies are needed to investigate the relationship between the gait parameters and health outcomes.

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.
