ABSTRACT

Objectives

To examine the effect of core stability on parameters of coordinated movement of the trunk and lower extremities in post-stroke rehabilitation.

Methods

A total of 55 subjects (mean age, 58 years) were included in the study: 33 patients after stroke (17 with ischemic cerebral stroke and 16 with cerebellar) and 22 neurologically healthy subjects with lower back pain. Participation was voluntary. All subjects were asked to complete two exercises: a dynamic movement in the seated position (leaning forward and back) and a march-in-place exercise with a high elevation of the knees. The two exercises were performed with and without contraction of the abdominal muscles. The frontal and sagittal inclination of the trunk during movement, gait speed, elevation of the feet, and muscle tension was recorded. Clinical Trial Registration-URL: http://www.clinicaltrials.gov. Unique identifier: NCT04886466.

Results

Core stability (abdominal contraction) was associated with more precise trunk movement in the frontal and sagittal plane, as well as higher elevation of the feet and a faster gait. This occurred in both post-stroke patients and neurologically healthy subjects with lower back pain.

Discussion

Muscle tensions were generally lower in post-stroke patients compared to those with lower back pain syndrome but active abdominal tension muscles caused the increase of core stability and alter the trunk movement path, and improves gait and range of movement. Core stability training during stroke rehabilitation may help patients to achieve a higher level of coordinated movement.

核心稳定性对中风康复中人体协调运动的重要性

摘要

目标

研究核心稳定性对中风后康复中躯干和下肢协调运动参数的影响。

方法

共有 55 名受试者（平均年龄 58 岁）被纳入研究：33 名卒中后患者（17 名缺血性脑卒中和 16 名小脑）和 22 名神经系统健康的腰痛受试者。参与是自愿的。所有受试者都被要求完成两项练习：坐姿的动态运动（向前和向后倾斜）和膝盖高度抬高的原地行进运动。这两个练习是在有和没有腹肌收缩的情况下进行的。记录运动过程中躯干的前倾和矢状倾角、步态速度、脚的抬高和肌肉张力。临床试验注册-URL：http://www.clinicaltrials.gov。唯一标识符：NCT04886466。

结果

核心稳定性（腹部收缩）与在正面和矢状面上更精确的躯干运动，以及更高的足部抬高和更快的步态有关。这发生在中风后患者和患有腰痛的神经系统健康受试者中。

讨论

与腰痛综合征患者相比，中风后患者的肌肉张力通常较低，但活跃的腹部张力肌肉会增加核心稳定性并改变躯干运动路径，并改善步态和运动范围。中风康复期间的核心稳定性训练可以帮助患者达到更高水平的协调运动。
