概括
在退行性宫肌病 (DCM) 中,临床下膝盖延伸器的软弱与步态和平衡的差异有关. 在DCM患者中,最大自发异位收缩 (MVICs) 可以客观地测量这种运动损伤.
科学领域:
- 神经学
- 整形医学
- 脊髓医学
背景情况:
- 退行性宫髓病 (DCM) 是老年人非创伤性脊髓疾病的主要原因.
- 即使没有明显的腿部软弱, 步行不稳定和平衡问题也很常见.
研究的目的:
- 通过最大自发异位收缩 (MVICs) 测量下肢的亚临床弱点与DCM患者的步态和平衡障碍之间的关联.
主要方法:
- 对手术前DCM参与者的前性观察研究.
- 测量了膝盖延伸器和脚脚曲器MVIC,伯格平衡量 (BBS) 分数,步行速度,时空步行参数,以及修改的日本整形医学协会 (mJOA) 分数.
- 使用多变量回归分析关联,控制年龄和性别.
主要成果:
- 膝盖延伸器的MVIC与步行速度,mJOA下肢分数和BBS分数呈正相关性.
- 在回归模型中调整年龄和性别后,这些关联仍然显著.
- 脚足曲器MVIC与步态或平衡结果没有显著关联.
结论:
- 膝盖延伸器MVIC反映了亚临床弱点,并与DCM的步态和平衡受损有关.
- MVIC提供了一个有前途的客观措施来量化DCM的动力缺陷.
- 这突显了在管理DCM时评估细微的下肢弱点的重要性.

Bones of the Lower Limb: Femur and Patella
8.2K
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...

Muscles of the Leg that Move the Foot and Toes
5.1K
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....

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
773
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
