Cohort study 

研究目的:

1.探究不同下肢Brunnstrom分期(III 期、IV 期、V 期)的卒中患者与健康对照组在步态协调性及协调稳定性方面的差异 2.探究不同下肢Brunnstrom分期(III 期、IV 期、V 期)的卒中患者与健康对照组在步态周期时间序列下的步态协调性的差异 3.探究不同下肢Brunnstrom分期(III 期、IV 期、V 期)的卒中患者患侧与非患侧及健康对照组在下肢肌肉力学特性(张力、硬度、粘弹性)方面的差异 4.探究肌肉力学特性的改善与步行协调性及稳定性的改善是否存在相关性 5.探究肌肉力学特性、临床评估和人口统计学因素如何预测卒中患者步行协调性的改善  

Objectives of Study:

1. To investigate the differences in gait coordination and coordination stability between stroke patients with different lower limb Brunnstrom stages (stage III, IV, V) and healthy controls. 2. To investigate the differences in gait coordination between stroke patients with different lower limb Brunnstrom stages (III, IV, V) and healthy controls in terms of gait cycle time series. 3. to investigate the differences in the mechanical properties (tension, stiffness, viscoelasticity) of the lower limb muscles between the affected and unaffected sides of stroke patients with different lower limb Brunnstrom's stages (III, IV, V) and healthy controls. 4. To investigate whether there is a correlation between improvements in muscle mechanics and improvements in walking coordination and stability. 5. to investigate how muscle mechanical properties, clinical assessment and demographic factors predict improvements in walking coordination in stroke patients.

指标类型:

主要指标

Outcome:

Muscle mechanical properties

Type:

Primary indicator

测量时间点:

首次入院时评定基线水平 以及 约30天后 出院时进行后测

测量方法:

肌肉力学特性(肌张力、硬度、粘弹性):使用Myoton pro进行肌肉力学特性的测量时,分别让研究参与者处于卧位和立位下进行测量,同一研究参与者在基线测量和出院前测量时在同一房间进行测试,室温保持在 25?C且测量时间为同一时间(±1 小时)进行。 研究参与者先仰卧在检查台上休息5分钟。测量从左侧开始,依次测量选定肌肉,每个肌肉左右两侧均进行测量。测试端垂直于被测肌肉肌腹中部 ±5°,按压至设备

Measure time point of outcome:

Baseline levels are assessed at initial admission and post-tests at discharge approximately 30 days

Measure method:

The test end was placed perpendicular to the middle of the muscle belly of the tested muscle ±5°. The device was pressed until the device indicator light changed from red to green and the device emitted a mechanical pulse stimulus, applying a preload of 0.18 N and a mechanical pulse of 0.40 N to the muscle with a pulse duration of 15 ms, which resulted in a naturally damped oscillation in the muscle and the automatic calculation of muscle biomechanical parameters. Measurements were repeated if t
