概括
心血管健康 (CRF) 没有预测多发性硬化症症状的长期变化. 基线表现,而不是CRF,是影响两年结果的关键因素.
科学领域:
- 神经学 神经学
- 康复科学 康复科学 康复科学
- 运动生理学 运动生理学
背景情况:
- 多发性硬化症 (MS) 的特征是神经退行导致渐进的认知和运动障碍.
- 据推测,心肺呼吸能力 (CRF) 可以减轻与MS相关的衰退,但其纵向影响尚未得到充分证实.
- 了解影响疾病进展的因素,特别是不依赖复发活动 (PIRA) 个体的进展,对于有效管理至关重要.
研究的目的:
- 在患有多发性硬化的人群中,研究基线心肺呼吸能力 (CRF) 与两年内行为 (手的敏捷性,认知) 和神经生理 (皮层脊髓刺激性) 结果的变化之间的纵向关联.
- 确定CRF是否预测MS患者没有复发的功能和神经生理变化 (PIRA).
主要方法:
- 一组38名MS患者在基线和大约两年后接受了评估.
- 心肺呼吸能力 (CRF) 用最大的氧气吸收量 (
- 行为结果包括九洞测试和蒙特利尔认知评估;神经生理结果通过跨磁刺激评估皮质脊髓刺激能力.
主要成果:
- 在为期两年的研究期间,基线CRF没有显著预测手工灵巧度,认知功能或皮质脊髓刺激能力的纵向变化 (p = 0.1780.655).
- 基线初始表现成为后续结果的最强有力的预测因素.
- 虽然整体CRF没有预测变化,但蒙特利尔认知评估 (p = 0.002) 和非主导手九孔测试 (p = 0.036) 随着时间的推移而显著改善.
结论:
- 患有多发性硬化症的个体中,心肺呼吸能力 (CRF) 似乎不是关键功能和神经生理结果的纵向变化的重要预测因素.
- 基线功能表现是未来结果的关键决定因素,强调其作为早期康复干预的目标的重要性.
- 观察到的疾病进展的个体间变异性强调了MS的异质性质和个性化管理策略的必要性.

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Induced-fit Model

Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Goodness-of-Fit Test
9.2K
The goodness-of-fit test is a type of hypothesis test which determines whether the data "fits" a particular distribution. For example, one may suspect that some anonymous data may fit a binomial distribution. A chi-square test (meaning the distribution for the hypothesis test is chi-square) can be used to determine if there is a fit. The null and alternative hypotheses may be written in sentences or stated as equations or inequalities. The test statistic for a goodness-of-fit test is given as...

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
