概括
与单边CAI患者相比,双边慢性脚不稳定 (CAI) 患者的姿势控制较差,肌肉激活发生变化. 这些发现突出了明显的感觉运动处理差异,为CAI患者提供了个性化康复信息.
科学领域:
- 生物力学 生物力学
- 神经科学是一个神经科学.
- 运动医学 运动医学
背景情况:
- 慢性脚不稳定性 (CAI) 与姿势控制和肌肉激活缺陷有关,可能表明中央感觉运动变化.
- 现有的研究还没有明确定义双边CAI和单边CAI的个体之间的姿势控制和肌肉激活的差异.
- 澄清这些区别对于为CAI量身定制有效的康复策略至关重要.
研究的目的:
- 研究双边CAI,单边CAI和健康对照个体之间的姿势控制和肌肉激活的差异.
- 为了确定双边CAI,单边CAI和健康对照是否表现出不同的感觉运动功能模式.
- 提供数据,可以为不同的CAI介绍提供有针对性的干预措施的发展信息.
主要方法:
- 招募了三个组:18个双边CAI的个人,18个单边CAI的个人,18个健康的对照.
- 在单腿姿势任务中评估压力中心 (COP) 和集成肌电图 (iEMG).
- 利用单向ANOVA对不同组的功能结果,姿势控制 (COP速度) 和肌肉激活 (iEMG) 进行比较.
主要成果:
- 双边CAI组表现的姿势控制 (中侧和前后COP速度) 比单边CAI和对照组要差得多.
- 单方面CAI组表现出与健康对照组相比的姿势控制.
- 与对照组相比,双边CAI组显示前iEMG增加,而单边CAI组显示前iEMG减少.
结论:
- 在单腿姿势期间,双边和单边CAI的个体之间存在着姿势控制和肌肉激活的显著差异.
- 这些发现表明,在双边与单边的CAI中,中枢神经系统的感觉运动处理有所差异.
- 了解这些具体差异对于制定个性化治疗计划至关重要,以改善患者的治疗结果并降低反复脚扭伤的风险.

Ankle Joint
1.9K
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...

Muscles of the Leg that Move the Foot and Toes
2.3K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
