概括
在中风幸存者中,坚硬的膝盖步伐最好通过四肢之间峰值摆动膝盖屈曲的差异来识别. 这种方法在不同的步行速度上是可靠的,有助于准确的诊断.
科学领域:
- 生物力学 生物力学
- 神经学 神经学
- 康复医学 康复医学 康复医学
背景情况:
- 膝盖硬的步态影响了25-75%的中风后患者,其特点是摇摆阶段膝盖屈曲有限.
- 不一致的诊断措施,包括峰值膝盖曲角度和时间,阻碍了可靠的确定硬膝盖步态.
研究的目的:
- 在中风后的个体中评估不同Stiff-Knee步态定义的一致性,有效性和准确性.
- 为了建立可靠的诊断标准,在中风幸存者的坚硬膝盖步态.
主要方法:
- 对50名中风后参与者 (24名有硬膝行走和26名没有硬膝行走) 进行了单变群分析.
- 斯皮尔曼的等级相关性和五种聚类技术评估了定义的有效性.
- 临床医生的评估被纳入有效性分析.
主要成果:
- 峰值膝盖屈曲时间和过度伸展与减少摇摆阶段膝盖屈曲的相关性不佳.
- 峰值摆动膝盖屈曲角度和自选速度的角度之间的肢体间差异是最有效的差异化因素.
- 在更快的速度下,四肢间的差异显示出高灵敏度和F1分数.
结论:
- 杆 <44.3°峰值摆动膝盖曲和>17.0°四肢间的差异,在自行选择的速度确定了硬膝盖步态.
- 峰值摆动膝盖屈曲角度的四肢间差异是推用于诊断中风后的坚硬膝盖步态,因为它的步态速度坚固.

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
01:10Ankle 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...
01:28Muscles of the Leg that Move the Foot and Toes
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.
