The shoulder is the the most unstable joint in the body and comprises by 3 main parts the glenoid, the humerus and the scapula (shoulder blade). The shoulder joint is stabilised by several structures; ligaments, capsule and the tendons of the rotator cuff. The rotator cuff is made up of 4 muscles, SUPRAPINATUS, INFRASPINATUS, TERES MINOR and SUBSCAPULARIS. These muscles work together to rotate the arm inwards and outwards and also work to take the arm away from the body to the side. These muscles can be injured in several ways with repetitive movements, trauma, muscular imbalance or adaptive postures.
In anatomy, the scapula (plural scapulae or scapulas)
Osteoarthritis, commonly known as wear-and-tear, is a condition in which the natural cushioning between joints, the cartilage, becomes worn. When this happens, the bones of the joints rub more closely against one another with less of the shock-absorbing benefits of cartilage. The rubbing results in pain, swelling, stiffness, decreased mobility and, sometimes, the formation of bone spurs.
Myofascial trigger point dry needling is a technique used to release myofascial trigger points. It involves the insertion of sterile single use acupuncture needles into the muscle to target a trigger point. This causes a local twitch response, the muscle contracts and relaxes. This causes a chemical response which helps to inhibit the pain/inflammatory cycle.
