The repetitive nature of typing, using a mouse, and maintaining incorrect postures can strain the muscles, tendons, and ligaments surrounding the shoulder joint.

Understanding the Anatomy of the Shoulder

Before exploring the causes of shoulder pain, it is essential to have a basic understanding of the shoulder’s anatomy. The shoulder joint is a complex structure consisting of bones, muscles, tendons, and ligaments that work together to facilitate a wide range of movements. The main bones involved are the humerus, scapula, and clavicle. The rotator cuff, a group of muscles and tendons, provides stability and allows for controlled rotation of the arm. Understanding this anatomy will help you grasp how computer use can affect the shoulder and why pain may occur.

The Bones of the Shoulder

The humerus, commonly known as the upper arm bone, connects to the scapula, or shoulder blade, at the glenoid cavity. This ball-and-socket joint enables the arm to move in various directions. The clavicle, or collarbone, provides additional support and stability to the shoulder joint.

The Rotator Cuff

The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint, forming a cuff-like structure. These muscles include the supraspinatus, infraspinatus, teres minor, and subscapularis. The rotator cuff not only helps with shoulder movement but also plays a vital role in stabilizing the joint, preventing dislocation and injury.

The Shoulder Ligaments

Ligaments are strong bands of connective tissue that connect bones to other bones, providing stability to the joint. In the shoulder, there are several important ligaments, including the acromioclavicular (AC) ligament, coracoclavicular (CC) ligament, and glenohumeral ligaments. These ligaments help maintain the alignment of the bones and prevent excessive movement that could lead to pain and instability.

Common Causes of Shoulder Pain from Computer Use

Shoulder pain related to computer use can have multiple causes. Understanding these causes will allow you to identify potential risk factors and make necessary adjustments to prevent or alleviate shoulder pain.
