Musculoskeletal system disorders.


The extensor muscles are made “erect” (they oppose the flexor muscles and gravity to keep the body upright).
Posture is the usual position of the human body.
A straight back, straightened shoulders, an extended chest, a raised head are all signs of good posture. Correct posture is essential for the normal position and function of the internal organs.

In case of incorrect posture, flattened, drooping shoulders and a sunken chest make it difficult for the internal organs (primarily the lungs and heart) to work. Improper posture can lead to osteochondrosis: a person’s spinal column is bent, intervertebral discs are damaged. Due to disorders of the spine, pinching of the spinal nerves can occur, the head begins to ache, pains in the neck and back appear. Also, with a curved spine, internal organs can be displaced, due to which their work deteriorates.

Correct posture should be taken care of from early childhood. In children and adolescents, until the cartilaginous tissue is replaced by bone, significant deviations of the bends from the norm are possible – these are curvature of the spine: kyphosis, lordosis, scoliosis.

To prevent curvature of the spine and maintain correct posture, you must strictly monitor the correct seating position at the table, computer, etc.

A curvature of the spine acquired in childhood is difficult to correct later due to ossification of the spine in adulthood.

Flat feet

Another violation of the skeletal structure is flat feet. It consists in flattening the arch of the foot.

In humans, the foot has a vault. This allows you to reduce the loads that appear during running, jumping, when carrying weights. If the foot becomes flat and cannot reduce the load, then when walking, running and even just standing, the legs quickly get tired and severe pain occurs.

In children, the development of flat feet is affected by early wearing of high-heeled shoes, wearing tight shoes or shoes without heels. Sometimes it is associated with metabolic disorders, overweight (obesity) and hereditary factors.

To prevent flat feet, you need to wear comfortable shoes with a small heel. Walking barefoot is recommended. Special exercises to strengthen the muscles of the foot are also helpful.

An instep support is an orthopedic product (insole) that is used for flat feet or to prevent the development of flat feet.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
