概括
患有巨大的旋转部撕裂的患者在抬起手臂时显示肌肉激活发生变化. 对deltoid肌肉,前肌肉和梯形肌肉的向物理治疗可以改善那些患有伪的功能.
科学领域:
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
- 康复科学 康复科学 康复科学
背景情况:
- 巨大的旋转手套撕裂 (MRCT) 往往导致肌肉激活模式在活跃的上肢升高期间发生变化.
- 了解这些模式对于开发有效的物理治疗干预措施至关重要,特别是对于那些可能不是手术候选人的伪症患者.
研究的目的:
- 调查和澄清在MRCT和nonpseudoparalysis患者的活跃上肢升高期间,deltoid和periscapular肌肉的特定肌肉激活模式.
- 为了为患有伪症的患者提供针对性物理治疗的处方信息.
主要方法:
- 在31个MRCT患者的肩膀 (积极的肩膀曲≥90°) 和27个对照组中,使用表面肌电图比较肌肉激活比率 (R-肌值).
- 测量了三个肩曲间隔 (0°-30°,30°-60°,60°-90°) 的骨 (前部,中部,后部),梯形 (上部,中部,下部) 和骨前部 (SA) 的激活.
- 利用波恩费罗尼调整的方差分析进行群体之间的统计比较.
主要成果:
- 与对照人群相比,MRCT患者在0°-30°曲间隔期间,在所有三种骨部件中表现出显著更高的R肌值.
- 在MRCT组中,在30°-60°间隔期间,在后部角质肌,下部SA肌,上部和中部梯形肌中也观察到较高的R肌值.
结论:
- 研究结果表明,MRCT患者的肌肉激活有明显的差异,特别是涉及三角形肌,下部SA肌,上部/中部梯形肌.
- 康复策略应侧重于在肩曲过程中以不同的角度激活这些特定的肌肉,以帮助从伪麻到非伪麻的过渡.
- 这项研究支持基于证据的物理治疗,以改善MRCT患者上肢功能.

Muscles that Move the Arm
4.7K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Muscles of the Shoulder
8.9K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Muscle Coordination and Action
3.0K
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.

Muscles that Move the Head
5.6K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Bones of the Upper Limb: Humerus
6.9K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
