概括

动力学变量分组有效地区分了在功能任务中患有骨疼痛 (PFP) 的女性与健康个体. 运动模式根据特定活动而异,这表明PFP的可适应策略.

科学领域:

生物力学生物力学
运动学运动学
运动科学运动科学

背景情况:

椎关节疼痛 (PFP) 是功能活动期间机械障碍的特征.
研究调查了PFP种群中机械因素,疼痛和不对齐之间的联系.
了解动力学差异对于评估和治疗PFP至关重要.

研究的目的:

确定不同的动力学变量分组如何区分患有PFP的女性和无症状女性.
分析各种功能任务中的动力学模式.

主要方法:

在35名PFP女性和35名对照女性 (18-30岁) 中,对7项功能任务进行3D动力学分析.
动力学变量被分为近距离,局部,远距离和不对齐集.
运动偏差概况 (MDP) 和Z分数被用来区分基于动态集的群体.

主要成果:

动力学集合的区分能力因功能任务而有很大差异.
距离变量是着陆的关键,近距离+局部用于推进,近距离用于爬楼梯.
靠近+远距离套件在下楼梯时最有效,而不对齐变量在下楼梯和步行任务中是显著的.

结论:

特定任务的动力学变量集可以将PFP女性与对照女性区分开来.
患有PFP的个体表现出受特定功能任务影响的适应性运动策略.
这些发现可以加强临床评估,并为有针对性的PFP治疗策略提供信息.

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...
