Shoulder pain is one of the most common issues people face today. The shoulder is a very complex set of muscles and bones designed for a large variety of movements. In order to gain that freedom of movement, evolution had to sacrifice some stability. This makes shoulders especially vulnerable to injury. Both impact injuries such as a torn rotator cuff, and overuse injuries such as a pinched nerve. Thankfully, shoulder pain massage can work wonders on many types of shoulder pain.
How Your Shoulders Work – Two Joints, Not Just One!
The shoulder actually consists of two distinct joints, the shoulder joint and the shoulder girdle.
The Shoulder Joint
The arm bone (humerus) connected to socket of the shoulder blade makes up the shoulder joint. The shoulder joint allows for movement of the arm in many directions. All while keeping the shoulder blade locked in place. Your shoulder joint can move your arm forwards, backwards, sideways. As well as rotating your arm in the socket.
There are many different muscles that attached to the humerus and allow for these movements. The pectoral major, latissimus, and deltoid create forwards, backwards, and sideways movements of the arm. The rotator cuff set of muscles creates rotational movements. Contrary to popular belief there is no “rotator cuff muscle.” The rotator cuff actually refers to a set of 4 different muscles: supraspinatus, infraspinatus, teres major, and subscapularis.
