children who are partially or completely limited in voluntary movements. Depending on the nature of the disease and the severity of the deficiency, children are conventionally divided into 3 groups. The first group includes children suffering from residual manifestations of peripheral paralysis and paresis, isolated disorders of the foot or hand, mild manifestations of scoliosis, etc. The second group includes children suffering from various orthopedic diseases caused mainly by primary lesions of the musculoskeletal system (with the preservation of the motor mechanisms of the central and peripheral nervous system), as well as children suffering from severe forms of scoliosis. A special group consists of children with the consequences of poliomyelitis and cerebral palsy, in whom musculoskeletal disorders are associated with developmental pathology or damage to the motor mechanisms of the central nervous system.
