Most of the population suffers from middle back pain. Especially the one who spends more than 10 hours sitting. That is why the importance of sitting in a chair that matches according to the ergonomics of your body.
The pain that appears in the central area of the spine is called dorsalgia, the dorsal column is made up of twelve dorsal or thoracic vertebrae that are between the cervical and lumbar areas, forming the middle part of the spine.
The Dorsal Column is located in the posterior part of the back and presents a slight kyphosis of base, that is to say, a backward curvature (concave forward and convex backward) that is continued in turn with the ribs on the side.
This region of the spine is reinforced by a series of muscles that are inserted and described below, which are responsible for the persistent and diffuse pain of the middle back pain. These muscles tend to contract, generating fibrosis, shortening and muscle spasm.
The main muscles that generate the painful picture of the middle back pain are those that are deep to the trapezius muscle; they are minor and major rhomboids and the underlying spinal musculature, below this. The angle of the scapula, even though it is closely related to the cervical spine, is also usually a very involved muscle within the dorsal pain picture.
MOST FREQUENT CAUSES:
Most of the pains are related to posture. Maintain inappropriate postures, whether sitting or standing. Most of these pains are located in the soft tissues: ligaments and muscles mainly. Although less frequent, other causes not associated with the spine should be ruled out, such as angina pectoris, gastrointestinal problems, tumors, etc. These conditions can produce pain patterns similar to those caused by musculoskeletal injuries.
Inadequate postures are a trigger of these pains, chronic middle back pain is also related to phenomena of psychic affectation (stress, depression and anxiety).
Other less frequent causes are related to degenerative processes of the intervertebral discs (discopathies) and the intervertebral joints (spondyloarthrosis), infections and tumors.
Flat back, that is to say loss of the curvatures of the column, generally by muscular contracture.
Rarely, deformities such as scoliosis or kyphosis alone cause middle back pain, it is usually necessary to look for any additional associated pathology.
