概括
虚拟现实 (VR) 沉浸,特别是在运动中,抑制了上肢的脊柱刺激能力 (H-反射). 这些神经肌肉变化在VR使用后仍然存在,这表明对虚拟训练和康复有影响.
科学领域:
- 神经科学是一个神经科学.
- 人体生理学 人体生理学
- 虚拟现实技术 虚拟现实技术
背景情况:
- 在动态环境中的神经肌肉适应,特别是在虚拟现实 (VR) 中的视觉和情绪状态改变的情况下,并未得到充分理解.
- 虚拟现实可以模拟运动恶心等情况,并调节同情性兴奋,影响感觉运动集成.
- 在VR中使用唤起的反射来评估上肢感官运动控制是一种新的方法.
研究的目的:
- 在虚拟现实 (VR) 暴露期间调查上肢的神经肌肉适应.
- 检查改变视觉反,运动感知和情绪状态对感觉运动集成的影响.
- 评估手半径肌 (FCR) 肌肉中电气引起的 (H反射) 和机械诱导的 (噪音肌振动;NTV) 反射的变化.
主要方法:
- 18名参与者接受了四种条件:基线现实世界,静止VR,动态VR (过山车) 和后VR.
- 保持了柔软手臂半径 (FCR) 肌肉的同位数次最大激活.
- 电肌图 (EMG),H反射,NTV反射,电皮活动 (EDA) 和运动性疾病问卷被用于测量神经肌肉和生理反应.
主要成果:
- 在动态VR期间,H反射幅度被抑制,并在VR后持续存在,而NTV反射则保持不变.
- 交感兴奋 (EDA) 和运动恶心症状在动态VR期间显著增加,但在VR后恢复到基线.
- 在FCR和brachioradialis中肌肉激活得到维持,但在VR沉浸过程中双臂肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌
结论:
- 带有运动感知的VR抑制了脊柱刺激能力 (H-反射),这表明感觉运动控制发生了变化.
- 一致的肌肉敏感度 (NTV-反射) 表明潜在的融合运动适应性来维持功能.
- 在VR后持续的H反射抑制突出显示了持久的神经肌肉效应,为VR在康复和训练中的应用提供了进一步的研究.

Somatic Spinal Reflexes
2.7K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Reflex Activity
2.0K
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.
