Poor posture results from certain muscles tightening up or shortening while others lengthen and become weak, which often occurs as a result of one’s daily activities. There are different factors that can impact on posture and they include occupation activities and biomechanical factors such as force and repetition. An example of this would be working at a computer all day long.

Risk factors for poor posture also include psychosocial factors such as job stress and strain. Workers who have higher job stress are more likely to develop neck and shoulder symptoms.
