概括

足部内在肌肉 (IFM) 的大小和质量在下肢疾病中存在差异,例如慢性脚不稳定和关节疼痛. 这些发现突显出需要在康复中评估和准IFM以改善脚部和脚功能.

科学领域:

生物力学和肌肉骨健康
脚和脚的解剖学和功能
下肢疾病的临床评估

背景情况:

足部内在肌肉 (IFM) 对足部和脚的稳定性至关重要.
这种功能障碍与各种下肢损伤有关.
在慢性脚不稳定 (CAI),关节疼痛 (PFP) 和糖尿病等疾病中对IFM的功能评估仍然具有挑战性.

研究的目的:

在不同患者组和健康对照组中比较足部内在肌肉 (IFM) 尺寸和组织质量.
在患有CAI,PFP,第1次甲关节 (第1次MTPJ) 关节缺陷和糖尿病的个体中研究IFM形态.

主要方法:

超声波成像 (USI) 评估了Abductor Hallucis (AbH) 和Flexor Digitorum Brevis (FDB) 肌肉的横截面 (CSA) 和回声效应.
119名参与者包括患有PFP,CAI,第1次MTPJ关节障碍,糖尿病和健康对照患者.
协同变异分析 (ANCOVA) 对照年龄和性别的组.

主要成果:

在大多数病理组和对照组之间发现了显著的AbH肌肉大小 (CSA),不包括第1组MTPJ.
在大多数组中,FDB肌肉大小 (CSA) 有显著差异,除了PFP和第1MTPJ.
肌肉质量 (回声效应) 在AbH和FDB两组之间有显著差异,CAI,第一MTPJ和PFP组的FDB回声效应更高.

结论:

这项研究为多个临床群体的IFM规模和质量提供了新的见解.
观察到的IFM形态变化表明可能是康复的目标.
临床医生应考虑评估和治疗IFM以改善受影响个体的脚功能.

Muscles of the Leg that Move the Foot and Toes

Muscles 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....

Pulse Assessment Sites

Pulse 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...
