概括
年长的女性表现下脚动态关节硬 (DJS) 由于减少脚时刻,需要脚支. 观察到膝盖DJS差异,但没有解释女性膝关节骨关节炎 (OA) 的原因.
科学领域:
- 生物力学 生物力学
- 老年学是一门学科.
- 整形外科 整形外科 整形外科
背景情况:
- 膝关节关节炎 (OA) 不成比例地影响着老年女性.
- 步行辅助器件,如膝盖支架,旨在减轻膝盖压力并预防OA.
- 动态关节硬度 (DJS) 量化了辅助设备的阻力,这对于客观硬度处方至关重要.
研究的目的:
- 在老年人行走期间调查下肢DJS的基于性别的差异.
- 确定DJS是否在老年男性和老年女性之间在松平面上有所不同.
- 建立行走辅助器的性别具体建议的基础.
主要方法:
- 分析了132名健康的老年人 (65岁以上;71名男性,61名女性) 的数据.
- 在立场阶段的能量吸收过程中测量了部,膝盖和脚关节的DJS.
- 使用曼-惠特尼U测试和计算效果大小 (r值) 进行性别之间的DJS,联合游览和联合时刻的比较.
主要成果:
- 与男性相比,年龄较大的女性表现出明显的脚下部DJS和脚脚下屈曲瞬间减少 (p < 0.001,r = 0.35-0.42).
- 老年女性的膝盖DJS也较低 (p = 0.007),但效果大小小 (r = 0.24),因为关节外出和动作时刻没有显著差异.
- 在部DJS中没有发现任何显著的性别差异 (p = 0.703).
结论:
- 减少脚足底屈曲时刻可能会导致老年女性的脚下部DJS,表明需要脚支.
- 膝盖DJS观察到的差异目前无法解释老年女性膝盖骨质炎的较高发病率.
- 这些发现突显了老年人处方辅助设备的潜在性别特异性考虑因素.

Changes in the Appendicular Skeleton with Age
2.0K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Movement Joints in Buildings
123
Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...

The Effect of Aging on Tissues
2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Knee Joint
1.8K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Ankle Joint
1.6K
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...

Structural Joints: Synovial Joints
3.6K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
