概括

四肢的指缺陷与下部运动神经元 (LMN) 完整性和外在指肌肉活动有关. 诸如运动点映射和手动肌肉测试等评估可以确定脊髓损伤患者中指功能障碍的风险.

科学领域:

神经学神经学
康复医学康复医学康复医学
脊髓损伤研究脊髓损伤研究

背景情况:

四肢,由于椎脊髓损伤,往往导致功能障碍,包括指的错位.
大指功能障碍显著影响四肢患者的手部功能和独立性.
了解导致指错位的因素对于制定有针对性的康复策略至关重要.

研究的目的:

为了调查与指不定位相关的因素,影响四肢患者的手部功能.
分析下部运动神经元 (LMN) 完整性,外在指肌肉强度和指定位之间的关系.

主要方法:

对82名椎脊髓损伤患者 (C2-C8,AIS A-D) 的回顾性横截面研究.
通过使用运动点 (MP) 地图和手动肌肉测试 (MRC) 对三个外在指肌肉进行评估,159只手: flexor pollicis longus (FPL),延伸器 pollicis longus (EPL) 和吸收器 pollicis longus (APL).
将指的位置分为"按键","松的指"和"手掌中的指".

主要成果:

在三个指位置中观察到LMN完整性和肌肉强度的显著差异 (P<.0001).
无论是MP映射还是MRC值,在"宽松指"和"键扣"位置之间都有显著差异 (P<.0001).
flexor pollicis longus (FPL) 在"手掌中的指"组中显示出显著更高的MRC,与"钥匙捏"组相比 (P<.0001).

结论:

四肢症中指的错位与LMN的完整性和外部指肌肉的自愿肌肉活动有关.
MP映射和MRC评估是识别处于发展指错位风险的个体的有价值工具.
这些发现可以为开发干预措施提供信息,以改善四肢的指功能.

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Muscles that Move the Forearm

Muscles that Move the Forearm

The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
