Muscles of the Shoulder

Muscles of the Shoulder

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.

The anterior thoracic muscles include the serratus anterior, subclavius, and...

Muscles that Move the Arm

Muscles that Move the Arm

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...

Expansion and Contraction in Masonry Walls

Expansion and Contraction in Masonry Walls

Masonry walls are subject to slight expansion and contraction due to variations in temperature and moisture. Thermal movement in masonry is relatively straightforward to measure and plan for. On the other hand, moisture movement poses more of a challenge. New clay masonry units typically absorb water and expand over time under normal environmental conditions. Conversely, new concrete masonry units tend to shrink as they lose the excess moisture acquired during their production process.

Summary

This summary is machine-generated.

The wall push-up plus exercise causes significant scapular internal rotation and upward rotation. This shoulder movement pattern may increase the risk of shoulder impingement, suggesting cautious use in rehabilitation.

Area of Science:

Orthopedics
Sports Medicine
Biomechanics

Background:

The push-up plus exercise is widely used for shoulder rehabilitation.
Limited research exists on the specific kinematics of the wall push-up plus exercise.

Purpose of the Study:

To investigate the in vivo shoulder kinematics during the wall push-up plus exercise.
To determine if the exercise impacts the subacromial space.

Main Methods:

12 healthy volunteers performed the wall push-up plus exercise.
Bone pins and an electromagnetic tracking system were used to record scapular and humeral motion.

Main Results:

Significant increases in scapular downward and internal rotation were observed.
Glenohumeral motion included elevation and anterior translation relative to the scapular plane.

Conclusions:

The wall push-up plus exercise positions the scapula in a way that may predispose individuals to shoulder impingement.
Caution is advised when using this exercise in early shoulder rehabilitation, particularly for patients with subacromial impingement syndrome.
