PEMF for shoulder pain
The shoulder has a great range of motion; it can turn in many directions, and is therefore also easy to dislocate.
The shoulder is surrounded by different bones, and consists of three bones; the scapula (shoulder blade), the humerus (upper arm bone), and the clavicle (collarbone).
The humerus fits into the scapula like a ball and socket. The rotator cuff attaches the upper arm to the shoulder blade and helps you lift and rotate your arm. A lubricating sac sits between the rotator cuff and the bone, protecting the tendons and allowing free movement.
Among the many causes for pain in the shoulder are trauma, inflammation, tears, dislocations, fractures, and arthritis.
The shoulder tendons can become inflamed as a result of normal wear and tear. A tendon inflammation is called tendinitis or tendonitis, and its symptoms may be similar to another kind of inflammation called bursitis. Bursitis affects the Bursae, small sacs filled with fluid that reduce the friction between our tissues and bones. Excessive use of the shoulder can cause inflammation of the bursa thus leading to pain and swelling.
Dislocations and instability
A dislocation can be partial or complete, depending on whether the arm bone is partly or completely out of the shoulder socket. Dislocation of the shoulder joint can happen towards the front, the back, and downward. A forceful twist, blow, or fall usually causes a forward dislocation, the most common form of a shoulder dislocation.
After a dislocation, the shoulder remains vulnerable and may dislocate continuously. This condition is called chronic shoulder instability. “Separated shoulder” is sometimes used to describe a shoulder dislocation, however the joint involved in this case is the acromioclavicular joint and not the shoulder joint. A shoulder separation causes pain over the top of the affected shoulder, and is sometimes accompanied by a bump.
Shoulder fractures are usually the result of a fall or a direct blow to the shoulder. Among the most common shoulder fractures are clavicle, scapula, and humerus fractures, which cause severe pain and bruising.
Rotator Cuff Injuries
The rotator cuff muscles enable us to reach overhead. Minor injuries or repetitive lifting, as well as athletic activities requiring a lot of overhead motion, are common causes for rotator cuff injuries.
Tears to the rotator cuff tendons may also result in pain radiating down the side of the arm.
