Upper cross syndrome is a type of musculoskeletal disorder in the upper part of the body, which is caused by the presence of three abnormalities of kyphosis, head forward and shoulder forward. This syndrome can cause pain and difficulty in physical activities in all people, jobs and professions. Especially "carpet weavers".The process of carpet weaving is such that a person has to work for long hours statically and in an unfavorable body position. Working in static conditions and improper posture is considered as an important risk factor in the occurrence of musculoskeletal disorders.Upper cruciate syndrome in carpet weavers due to standing on the carpet loom for a long time without any support and sometimes doing repetitive activities and being in an inappropriate and wrong posture and non-standard ergonomics of the workplace causes the aggravation of this condition and especially the pain. Muscle imbalance can affect the natural alignment of the body and make it suffer from various postural abnormalities and make a person prone to acute and chronic injuries, especially upper crossed syndrome. In this syndrome, the upper and anterior posterior muscles of the neck and trunk region, which are part of the tonic muscles, are shortened and tightened, and the anterior deep muscles of the cervical spine and the posterior, middle, and lower shoulder girdle, which are mainly phasic, become inhibited, stretched and weakened. Therefore, it is necessary to investigate this complication more closely and provide prevention or correction solutions in this field. In this study, we will review this abnormality and provide controlling guidelines to improve the conditions of people working in the carpet weaving profession.
