A shoulder injury is one of the most common injuries sustained in the workplace since the shoulder joint involves many daily activities. Industries with the highest shoulder injury risk include the construction and landscape industries, mining and farming industries, and manufacturing and packaging industries. Recreational and professional athletes are also at risk of developing a shoulder injury. Physical trauma, accidents, and repetitive shoulder movements frequently cause a shoulder injuries at work. For example, pushing, pulling, and carrying heavy loads can cause minor shoulder joint damage and exacerbate a pre-existing shoulder condition like arthritis.
