概括

压力中心 (CoP) 的平方根平均值 (RMS) 和平均速度 (MV) 捕捉了站立平衡的不同方面. CoP RMS量化了摇摆,而CoP MV反映了姿势控制的努力,有助于全面的平衡评估.

科学领域:

生物力学生物力学
人类运动控制人体运动控制
姿势稳定性姿势稳定性

背景情况:

强力板通常用于测量站立平衡.
压力中心 (CoP) 平方根平均值 (RMS) 和平均速度 (MV) 是平衡文献中普遍存在的指标.
了解COP RMS和MV测量的特定姿势控制方面至关重要.

研究的目的:

阐明COP RMS和MV测量的姿势控制的不同方面.
为了澄清平衡研究中这两个常见的力板指标的含义.

主要方法:

分析压力中心 (CoP) 时间序列从静静站立时的力板数据.
从移动捕获数据计算的质量中心 (CoM).
计算了CoP,CoM的RMS和MV,以及前后 (AP) 和中侧 (ML) 方向的CoP-CoM差异.

主要成果:

CoP RMS与CoM RMS有很强的相关性 (r > .96),表明它测量了身体摇摆的程度.
CoP MV与CoP-CoM差异的RMS有很高的相关性 (r > .90).
CoP-CoM的差异与稳定性的扭矩产生有关,这表明CoP MV反映了姿势控制的努力.

结论:

CoP RMS有效量化了站立时身体摇摆的程度.
CoP MV有效量化了为了保持稳定的控制努力.
报告COP RMS和COP MV都提供了更完整的了解常态余额.

关键词:

在平衡控制中,控制平衡.质量中心质量中心.压力中心的压力中心姿势摇摆是一种姿势摇摆.站在一个立足的位置.

Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Reflex Activity

Reflex Activity

A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
A reflex exam is a diagnostic procedure performed by a healthcare professional to evaluate the functionality of a patient's...

Impression Management Techniques III: Aligning Actions

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...
