概括
噪音动前庭刺激 (nGVS) 提高了老年人的平衡,特别是当视觉和体感反有限时. 这表明GVS是老年人平衡康复的有希望的工具.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 康复科学 康复科学 康复科学
背景情况:
- 众所周知,噪音动前庭刺激 (nGVS) 可以改善姿势控制.
- 以前的研究主要集中在前庭系统的作用上,忽视了其他感官输入.
- 各种感官反来源对GVS诱导的姿势改善的贡献需要进一步研究,特别是在老年人中.
研究的目的:
- 研究视觉,体感和前庭反对老年人GVS后姿势控制改善的相对影响.
- 为了确定GVS的好处是否在缺乏感官反的情况下更明显.
- 评估GVS作为老年人平衡缺陷康复策略的潜力.
主要方法:
- 招募了47名参与者 (20人为对照组,27人为老年人).
- 使用感官整合修改后的临床测试来评估姿势控制.
- 老年人接受了GVS或假刺激,与基线和年轻成年人对照组进行了比较.
主要成果:
- 在老年人中,GGVS显著改善了姿势控制,但仅在视觉和体感反受损时.
- 降低前体反的个体中,改善更为显著.
- nGVS 的有效性是由感官反调节的,视觉和体感官线索具有主导影响.
结论:
- 在老年人中,GngVS显示出了恢复平衡困难的巨大潜力.
- 在视觉和体感官输入不可靠的情况下,GVS的好处最为明显.
- 感官反显著调节GVS对姿势控制的影响.

Major Somatic Sensory Pathways
863
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Indirect Motor Pathways
1.4K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...
