IS THE POSITION: This is the relation that the different parts of the body among themselves and with the space (eg. The relationship of the neck with respect shoulders), is a state of balance between body segments. When this ratio is incorrect, an imbalance that causes tension and stiffness, sometimes extreme, affecting the joints, ligaments, muscles and nerves causing pain. The goal of treatment is to relieve postural pain (see above) and reduce these tensions and rigidities, improving flexibility and joint mobility, stretching, strength and muscle definition and coordination. This type of treatment is done through specific exercises and stretching of certain muscles or muscle groups and strengthening and toning of others, breathing exercises, manual techniques, relaxation exercises, spinal stabilization exercises in (very useful in controlling destabilizing postural strength), mobility exercises, etc.
POSITION DEPENDS ON MUSCLE TONE , which is the state of muscle in semitensión rest. Explanation: There are 2 types of muscle fibers: the phasic (fast, serve to move and scroll) and tonic (slow, serve to maintain the position.) These fibers are different from each other at the cellular level, vascular, metabolic, etc. Let's talk about the tonic muscle. AG: It also calls for counteracting the force of gravity, these muscles are always semi-tight, as it is?: while some fibers of these muscles "work" (they are incurred), other "resting" (are relaxed), so they are very resistant to muscle fatigue and allowing for example that we stand for hours, which the phasic could not do and which by their nature are "used up" very quickly and that performing a movement against all its fibers. Tonic muscles are eg. the NTS (which are on the sides of the spine), soleus (leg), etc. Thanks to its permanent contractions can keep the position. But with this function?: muscles have a kind of sensor to the shortening or stretching (necessary stimulus for the muscle work) called the muscle spindle (made up of muscle fibers) that receives the order, and sends this information through nerve fibers to the spinal cord, there this information is integrated and stimulate motor neurons located in the anterior spinal moteneuronas calls that are "cablecito" that innervate the muscle fibers and cause the muscle to contract (this is called the stretch reflex). As the muscles pemanente tonics are shrinking, this reflex acts constantly and maintains proper muscle tone. When sick that affects muscle tone, this may increase (hypertonic) or decrease (hypotonic). It is noteworthy that in turn the muscle tone is regulated by central nervous system structures (cerebellum, brain and others).
tropism: the nutritional status that have a tissue, in the case of the muscles depends on several factors: the innervation free (if you lose muscle innervation eg. To see nerve injury altered the tropism) of its blood supply, metabolism and movement, eg. a person who had a cast for a month and does not move or contract your muscles will not upset their tropism, as well as a person that causes x was long in bed, then the muscles "thin", weaken, and so on., this is called atrophy or hypotrophy as the degree of alteration, hypertrophy is the increase in muscle size is achieved through resistance exercise, adequate food, etc.
