Body posture or posture is the position we take in space, it can be normal or abnormal. Nowadays, considering that people spend a large amount of time in front of the computer, television or on the mobile phone and at the same time adopt bad and irregular postures, various disorders occur, most often in the area of the spine. The most common bad postures in the spine area are: scoliosis and excessive lordosis and kyphosis. Back pain is a significant public health problem due to its high prevalence and is the most common cause of sick leave among the working population. Nurses do hard physical work during the daily care of patients due to back strain, poor ergonomic conditions lead to incorrect postures, and as a result, back strain and damage occur, resulting in back pain syndrome. Because of this, nurses use 30% more sick leave than other professions, while the overall prevalence of back pain syndrome is in the range of around 55%. An additional problem in nursing is the small number of health professionals, a large number of patients, the ergonomically unsuitable space in which nurses work, and a stressful environment. All of this significantly affects the occurrence of back pain syndrome. In order to reduce this number, preventive measures are important, which include: increasing the number of nurses, educating nurses, adjusting the space, reducing stress, and physical activity. The prognosis of back pain syndrome is usually good and does not require operative treatment. Therapy consists of rest, drug therapy and physical therapy, but pain syndrome due to heavy loads and injuries can cause permanent disability.
