Paresis represents weakening randomly of the arising movements that became result of disturbance of activity of motoriums of a head and/or spinal cord, peripheral nervous or central system. In other words, paresis is an incomplete paralysis.
On degree of manifestation paresis happens easy, moderate, deep and full, that is paralyzes. On localization on a body they are subdivided into paresis of one muscle, paresis of an extremity, part of an extremity, paresis of group of muscles, an akinetic mutism, a paraparesis and a paraplegia, biparez and a biplegiya, triparez and a triplegia. Besides, paresis can be psychogenic, peripheral, central and mixed.
Except paresis of muscles of a skeleton, this term can be used concerning vessels, a bladder, intestines.
Paresis can be both inborn, and acquired, that is to develop as a result of any postponed disease, etc. Inborn paresis of a hand, and only one has the greatest distribution. As a rule, they arise as a result during the birth the brachial plexus of the child is touched. In that case the movements are absent completely or are limited.
In sharp cases inborn paresis of legs and hands on the one hand, or only legs can take place. Such a case are frequent at children with malformations back or a brain. Many cases when children were born with damage of a brain, and in process of a growing, are known several years later, they began development of various paresis.
The acquired paresis practically in all cases is connected with disturbances in work of a peripheral or central nervous system – polyneurites, hereditary diseases, encephalitis, tumors of a nervous system, strokes.
For an assessment of expressiveness of paresis there is a special scale from zero to five points which reflects decrease in force of muscles. Zero points mean that autokinesias are absent and at the patient paralysis is observed, five points reflect the full volume of movements and normal force of muscles.
For paresis the atony, that is decrease in a muscle tone, an atrophy because of decrease in a nervous trophicity, involuntary reductions of separate muscle fibers which are perceived by the patient is inherent, and also are visible for the doctor. Besides, at paresis the hyper tone, that is strong increase of a muscle tone, increase of deep reflexes, presence of pathological reflexes, emergence of convulsive reductions at influence, emergence of consensual movements can be observed, for example, when the person squeezes a healthy brush, similar operations are performed also by a sick brush, however with a smaller force.
For treatment of paresis massage, heat which lead to improvement of a trophicity, development of nervous impulses are used. If muscular activity remains, the patient needs to see off as well special gymnastics, gradually increasing loading, using resistance.
