In the overwhelming majority of people of Western culture, it is easy to find several trigger points on the body — painful places in the muscle or points of attachment.
The design of the human body itself suggests the presence of such points with increased pain sensitivity, many acupuncture points are projections of trigger points. What are these points for and what to do if they hurt, read under the cut.
When a person is engaged in any activity, it is important for the brain to somehow distinguish situations that require the inclusion of different behavioral stereotypes. This is especially noticeable in the development of complex motor skills that require great accuracy and coordination.
Remember the child when he tries to draw a circle on paper for the first time - he curls over a piece of paper, pinches his tongue with his teeth, barely breathes and, with a shaking hand, tries to draw a circle.
Such an intense posture limits the degrees of freedom in an enormous number of joints, which allows the brain to more accurately differentiate the movements necessary for the successful completion of a task.
Every time a better figure is drawn, a child with less stress makes a movement, at some point in time that quality is achieved that does not require excessive tension in the body - the level of skill is achieved.
Forged posture requires the work of a large number of neurons to maintain muscle tone. The brain's resources for consciously maintaining the constrained posture are limited - you need to switch to another activity, which the child does, or to provide stiffness at the expense of reliable and enduring primitive reflexes of the spinal cord and brain stem.
Here the trigger points in the muscles or the places of their attachment enter the arena. Long enough tension in the muscle activates the soreness of the trigger point, the soreness causes a protective reflex, manifested in the tension of the muscle. A loop of biofeedback is formed, affecting only a few neurons in the chain, the overlying sections of the central nervous system release a resource for participation in other reactions.
Usually, it takes about 10-15 minutes to activate the trigger points, “the mode of getting into the situation”, after which the muscle clamp necessary for the work supports itself and the possibility of maximum immersion in work appears.
Since the maintenance of the clamp goes in the loop of positive biofeedback, then over time, the tension increases (tension provokes pain, pain provokes tension). This is usually felt as fatigue, forcing a change in activity in 45-90 minutes.
If the nature of the activity does not change for a long time, the pressure-sensitive points become actively painful, and the zone itself “drops out” of conscious attention so that chronic pain does not distract from the main activity for which there is a clamp.
If the tension lasts for more than two weeks, when you press on the point, a sharp pain arises, up to "up to the jump symptom". Over time, the skill of self-regulation of muscle tone degrades and “profession people” are obtained - according to the stereotype of posture and the location of the trigger points, it is often possible to determine the type of activity of a specialist.
The prevalence of chronic pain is huge, in pharmacies up to a quarter of the names of drugs - analgesics. Taking the pill allows you to reduce the impulses from the trigger points, which allows you to relieve muscle tension for a while and allow you to return the body to its original state during rest. If you persist and do not give rest, then at some point analgesics will cease to help and the person will be forced to go for treatment.
There is another way to get rid of chronic muscle pain and stress - to improve mastery of the skill to the level of the master. Thanks to a qualitatively new way of existence, the muscle clamps required for work are constantly changing, which immediately catches the eye of how coherence, accuracy, slow speed and quality of work.How to remove painful tension through errors?
