Objective To explore the related factors of immune function in movement disorder children with recurrent respiratory tract infection,and promote the comprehensive rehabilitation of children with movement disorders. Methods The clinical data of 80 patients with movement disorders were collected from the Department of Rehabilitation Medicine in Zhengzhou Children's Hospital,40 cases of recurrent respiratory tract infection during the rehabilitation treatment in group RRI,40 cases of children with movement disorders rehabilitation treatment for the same period as the control group,vitamin A,25-(OH)D₃,inorganic elements (iron,zinc,calcium,copper,magnesium,lead),immunoglobulin (IgA,IgM,IgG) were determined in two groups. Results Vitamin A (0.92±0.38 vs 1.24±0.35),25-(OH)D₃(24.7±5.2 vs 28.1±6.8),zinc (28.96±6.06 vs 44.68±8.70),iron (7.09±0.87 vs 8.25±1.14),calcium (1.31±1.83±0.12 vs 0.26) in RRI were significantly lower than those in the control group;The serum IgA (0.48±0.11 vs 1.32±0.25),IgM (0.88±0.19 vs 1.51±0.32) in RRI were significantly lower than those in the control group,no difference of IgG levels. Conclusions During the rehabilitation treatment of movement disorders children with recurrent respiratory tract infection,vitamin A,D,zinc,iron,calcium deficiency,low humoral immunity are related.To strengthen the monitoring of relevant factors regularly to give appropriate treatment and relative factors of abnormal,can enhance the body's resistance of movement disorder patients,reduce the incidence of recurrent respiratory tract infection rate and shorten the treatment course,and improve the curative effect of rehabilitation.
