概括
卒中幸存者表现出不对称的站立控制. 这项研究发现了和非四肢之间的肌肉协调的差异,揭示了不对称的皮质控制影响平衡.
科学领域:
- 神经科学是一个神经科学.
- 康复医学 康复医学 康复医学
- 生物力学 生物力学
背景情况:
- 在中风患者中,站立平衡控制的不对称损伤很常见.
- 这种残疾背后的神经肌肉特征在很大程度上仍未被描述.
- 了解肌肉间协调对于中风康复至关重要.
研究的目的:
- 为了研究中风患者在静静站立期间四肢之间肌肉间连贯性的差异.
- 为了识别肌肉激活和皮质控制的不对称模式.
- 阐明中风后站立平衡受损的神经肌肉基础.
主要方法:
- 在15名次急性中风患者中,从双边前肌 (TA),单肌 (SL) 和中部胃半肌 (MG) 肌肉记录了电肌图 (EMG).
- 患者在没有辅助设备的情况下进行了静静的站立任务.
- 计算了协同 (SL-MG) 和对抗 (TA-SL,TA-MG) 的肌肉对在三角 (0-5 Hz) 和β (15-35 Hz) 频段中的肌肉间连贯性,并比较了性和非性四肢.
主要成果:
- 在协同的SL-MG对中,在非paretic肢体中与paretic肢体相比,观察到显著更大的β频段连贯性 (p=0.017).
- 在对抗性TA-MG对中,与非对抗性肢体相比,在性肢体中发现了显著更大的三角波段连贯性 (p<0.01).
- 这些发现表明,在静静地站立时,脚下 flexor 肌肉的皮层控制不对称,肌肉协同作用发生变化.
结论:
- 脑卒中患者在静静地站立时表现出不对称的皮层控制足部 flexor 肌肉.
- 敌对肌肉之间的同步控制是肢的特征.
- 肌肉间连贯性分析揭示了异常的肌肉活动模式和不对称的皮质控制,有助于在次急性中风中损害平衡.

01:22Cardiac Output II: Effect of Stroke Volume on Cardiac Output
953
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

01:27Regulation of Stroke Volume
3.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
