概括
与标准的FES相比,自适应功能电刺激 (AFES) 在中风后的患者中显示出改善的足底曲器时间. 然而,总体而言,步态的改善有所不同,这表明需要个性化FES策略.
科学领域:
- 生物医学工程 生物医学工程
- 康复科学 康复科学 康复科学
- 神经科学是一个神经科学.
背景情况:
- 功能电刺激 (FES) 是一种常见的中风后步行康复技术.
- 现有的FES系统并不能为所有人带来临床上有意义的改善.
- 适应性FES (AFES) 系统旨在优化每步的刺激时间和振幅.
研究的目的:
- 评估一种新型AFES系统对功能步行结果的影响.
- 在中风后的个体中比较AFES与现有FES系统的疗效.
主要方法:
- 二十四个患有慢性中风后半的人参加了跑步机行走试验.
- 参与者接受了没有刺激,标准FES和新型AFES的试验.
- 测量了步行参数,包括步行速度,背部屈曲和推进力.
主要成果:
- 在各种刺激条件下,行走速度,峰值背部屈曲或推进力没有显著差异.
- 与固定速度跑步机相比,适应式跑步机上的步行速度和推进力显著更高.
- 与FES相比,与AFES相比, flexor刺激时间显著改善.
结论:
- 虽然AFES改善了脚部曲器的时间,但所有参与者的整体步态改善并不显著.
- 对FES反应的个体变异性表明需要个性化刺激策略.
- 需要进一步的研究来确定患者特异性反应,以优化FES用于中风后的步行康复.

Deindividuation
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.
Functionalism
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.

Facial Feedback Hypothesis
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...
The Role of Culture
Culture plays a crucial role in shaping self-identity and influencing thought and behavior, a foundational interest within social psychology. The multicultural perspective recognizes that individuals do not exist in a vacuum; instead, their experiences, perceptions, and actions are deeply influenced by the intersecting dimensions of their cultural, ethnic, and social group affiliations.Cultural Influence on Self-Identity and Social PerceptionCultural frameworks inform how individuals define...
Personal Identity
Personal identity is the deeply felt sense of self that individuals cultivate over time, intricately woven from intrinsic qualities they consider essential to their existence—qualities such as morality, intelligence, and friendliness. These attributes serve as vital internal benchmarks, guiding individuals in evaluating whether their actions resonate with their true selves.When personal identity takes center stage in one's life, individuals often emphasize their distinctiveness, highlighting...
