muscle lifting scapula function

Innervation

The muscle that raises the scapula is innervated by the branches of the third, fourth, and fifth spinal nerve roots.

Functions

As the name implies, the main function of the muscle lifting the scapula is the elevation of this movable bone. Preferably, this muscle displaces upward the top corner of the scapula, next to which it is attached to the bone. Thus, when contracted, it causes rotational movement of the scapula, in which the lower angle of the scapula moves towards the spine.

scapula muscle in Latin

With a fixed scapula, the fibers of this muscle, contracting, tilt the cervical spine in the appropriate direction and back.

Pathology

It is believed that the involvement of the muscles that lift the scapula in various pathological processes is one of the most frequent causes of painful "clamps" in the neck and shoulder girdle (the so-called "scapular-rib syndrome"). front staircase.

The development of such a pathological state is promoted by functional impairments - a consequence of the overstressing of the muscles that fix the scapula or set it in motion.

Circumstances leading to the development of the syndrome:

  • low level of mobility, hypodynamia;
  • passive lifestyle;
  • unusual intensive loads (sudden jumps, weightlifting), which is especially important for people who are not trained, whose muscles are not accustomed to physical exertion;
  • traumatic injuries (especially backhands, falls, road accidents).

Pain in this pathology can be of a different nature and have a different intensity (can be sharp, sharp, and can be nagging, arching; in some cases it takes a chronic course).

In acute cases, complex therapy is carried out, including:

  • drug effects designed to stop pain and reduce spasm;
  • physiotherapy;
  • massage (the course of massage should be carried out without aggravation, after the relief of pain syndrome);
  • special exercises.

The most effective preventive measure aimed at reducing the frequency and intensity of exacerbations is a special therapeutic gymnastics. Systematic implementation of simple exercises will strengthen the muscles, and the load will cease to cause pain in them.

How to develop a muscle that lifts the shoulder blade

As a rule, exercise complexes affect not only this muscle, but also others that have points of origin and attachment in the region of the bones of the shoulder girdle. Exercise, giving a load to this group of muscles, with systematic exercises contribute to strengthening the stabilizing muscles located between the shoulder blades, strengthening the back muscle group of the shoulder girdle, and, as a result, reducing or eliminating such features as stoop and protruding shoulder blades.

The following exercises will help to “pump up” this muscle:

  1. Starting position: hands are in front of the chest, forearms are horizontal, parallel to the floor; back straight. From this position movements are made, raising the elbows as high as possible; hands at the same time to change their position should not. In addition to the muscle lifting the scapula, in this simple exercise, trapezoidal, rhomboid, sternocleidomastoid muscles are involved in its various stages, the pectoral muscles (both large and small) and the middle portion of the deltoid muscle also work.
  2. Starting position: standing straight, arms slightly bent at the elbows.Taking a smooth, deep breath, during expiration as close as possible to bring the shoulder blades. In this position, the blades should be held no more than 30 seconds. The exercise should be repeated several times, without changing the position of the head and continuing to breathe calmly.

The implementation of a set of exercises is recommended to start with a small warm-up, and during classes to avoid sudden movements, jerks that can lead to injury.

Physical exercise for the muscle that lifts the shoulder blade should be performed in conjunction with the exercises for other muscles surrounding it, located in the shoulder girdle.
