摘要

本研究旨在利用智能手机测量脑卒中偏瘫患者单腿站立时的预期姿势调整特征。方法纳入20例脑卒中偏瘫患者和10例年龄匹配的健康对照。将智能手机连接到骨盆（L5），并测量单腿站立运动。主要数据是智能手机内置的加速的中外侧部分。在站立方向上达到加速度最大值的时间（峰值潜伏期）和移动量（峰值幅度）作为预期姿势调整特征量进行分析。发现脑卒中偏瘫患者的峰值幅度较对照组降低。此外，举双亲腿时的峰值幅度低于非双亲腿，举非双亲腿时的峰值潜伏期比举双亲腿时慢。非父母性腿抬高的峰值潜伏期与Fugl-Meyer评估和mini - best评分相关。本研究揭示了脑卒中偏瘫患者运动策略的预期姿势调整和不对称性降低。从偏瘫运动和平衡功能的角度来看，在抬起非偏瘫腿时，重心向偏瘫腿转移的时机很重要。

Characterization of anticipatory postural adjustments in patients with post-stroke hemiplegia using smartphones

Background

This study aimed to measure anticipatory postural adjustment characteristics of patients with stroke hemiplegia during one-leg standing using a smartphone.

Methods

Participants included 20 patients with stroke hemiplegia and 10 healthy age-matched controls. A smartphone was attached to the pelvis (L5), and one-leg standing movement was measured. The main data were the mediolateral component of the acceleration built into the smartphone. The time (peak latency) and amount of movement up to the maximum value (peak magnitude) of the acceleration in the stance direction were analyzed as the anticipatory postural adjustment feature quantities.

Findings

Patients with stroke hemiplegia showed a decrease in peak magnitude compared with controls. Additionally, the peak magnitude was lower when lifting the paretic leg than the non-paretic leg, and the peak latency was slower when lifting the non-paretic leg than the paretic leg. Peak latency of non-paretic leg elevation correlated with Fugl-Meyer Assessment and Mini-BESTest scores.

Interpretation

This study revealed decreased anticipatory postural adjustments and asymmetry in the motor strategies of patients with stroke hemiplegia. From the perspective of hemiplegic motor and balance functions, the timing of the shift in the center of gravity to the paretic leg when lifting the non-paretic leg is important.

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.
