The suprascapular nerve is a critical peripheral nerve that originates from the upper trunk of the brachial plexus, primarily responsible for innervating the supraspinatus and infraspinatus muscles. Its injury or entrapment can lead to shoulder pain and dysfunction, commonly seen in athletes and individuals with repetitive overhead activities.

Peripheral nerves are part of the peripheral nervous system, responsible for transmitting signals between the central nervous system and the rest of the body. They play a crucial role in sensory perception, motor control, and autonomic functions, making them essential for overall bodily function and coordination.

Shoulder pain can arise from a variety of sources, including muscular, skeletal, or nerve issues, and often requires a multifaceted diagnostic approach to determine the underlying cause. Treatment may involve physical therapy, medication, or surgery, depending on the severity and origin of the pain.

Shoulder Pain

Shoulder dysfunction refers to a range of conditions that impair the normal movement and function of the shoulder joint, often resulting from injury, overuse, or degenerative changes. Effective management typically involves a combination of physical therapy, medication, and sometimes surgical intervention to restore function and alleviate pain.
