When the European farmers (known as Boers) attempted to escape the monopolistic trading practices and autocratic rule of the company by moving into the interior, the company prohibited further expansion, ended the emigration of Europeans to the Cape, and expanded the use of slave labor.
Shoulder strains are the most common type of shoulder injury. Many shoulder strains occur in the front or anterior head of the deltoid, where the biceps runs underneath the deltoid. Shoulder strains can happen when someone lifts too much weight, jerks a heavy weight or object around, or falls.
Overuse and acute injuries are common causes of shoulder symptoms. Less common causes of shoulder symptoms include: 1  Muscle tension or poor posture. 2  Pain that is coming from somewhere else in your body (referred shoulder pain). 3  Breakdown of the cartilage that protects and cushions the shoulder joints (osteoarthritis). 4  Calcium buildup in the tendons of the shoulder.
