概括

患有慢性脚不稳定症 (CAI) 的人和健康的对照人表现出类似的反应,对走路时的感官干扰. 这两组在行走任务期间面临视觉和体感官信息改变时,都适应了他们的平衡策略.

科学领域:

生物力学生物力学
神经科学是一个神经科学.
肌肉骨损伤肌肉骨损伤

背景情况:

侧脚扭伤很常见,经常导致慢性脚不稳定 (CAI).
患有CAI的人更依赖视觉和体感官输入来保持稳定.
感觉组织测试 (SOT) 和机动感觉组织测试 (LSOT) 评估静态和动态任务期间的感觉重权.

研究的目的:

为了比较具有CAI和健康对照个体之间的SOT和LSOT表现.
为了研究在平衡和步行任务中,感官重权如何在CAI中不同.
为了确定视觉和体感官干扰对CAI稳定性的影响.

主要方法:

44名参与者 (23名有CAI,21名健康) 接受了SOT和LSOT评估.
SOT使用平衡得分 (压力中心) 测量了双腿平衡.
在扰乱条件下,LSOT评估了步态空间时间变量 (例如,姿态时间,步长).

主要成果:

无论是SOT还是LSOT都显示出显著的条件主效应,显示出改变的动力输出与感官干扰.
在SOT中的A组×条件相互作用表明,CAI组在一个特定条件下具有更好的平衡.
在SOT或LSOT中没有发现显著的群体间差异,这表明类似的适应策略在行走过程中对感官干扰产生影响.

结论:

渐进的感官干扰在受约束任务期间对有或没有CAI的个体的影响是相同的.
两组人都优先考虑稳定性,当导航步行扰乱.
体感和视觉障碍在CAI和健康个体中同样影响平衡.

关键词:

权衡 (静态) 的平衡.步态步态步态步态感觉重权重的重权重是指感觉重权重.时间空间的变化.视觉上的依赖视觉上的依赖

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

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...

Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
