Abstract：Objective To analyze the effect of lower limb robot in the treatment of lower limb movement disorders after stroke and its influence on walking and balance ability of patients.Methods A total of 110 patients with lower limb movement disorders after stroke who were hospitalized in the Second Affiliated Hospital of Air Force Military Medical University from January 2022 to November 2023 were selected.According to the random number table method,they were divided into the routine group and the observation group,with 55 cases in each group.The routine group was given routine rehabilitation training,and the observation group was given lower limb robot therapy on the basis of the routine group.The clinical efficacy,6-min walk test(6MWT)distance and Berg balance scale(BBS),simplified Fugl Meyer motor function scale(FMA),stroke specific quality of life scale(SS-QOL)scores,lower limb modified Ashworth scale(MAS)grading,levels of serum neuropeptide Y(NPY),brain-derived neurotrophic factor(BDNF),and nerve growth factor(NGF)were compared between the two groups.Results The total effective rate of the observation group was higher than that of the routine group[94.5％(52/55)vs 74.5％(41/55)](P=0.004).After treatment,the 6MWT distance,BBS,FMA and SS-QOL scores of the observation group were longer/higher than those of the routine group,the MAS grade was better than that of the routine group,the serum NPY level was lower than that of the routine group,and the serum BDNF and NGF levels were higher than those of the routine group(all P＜0.05).Conclusion Lower limb robot can effectively improve the walking ability,balance ability and motor ability of patients with lower limb movement disorders after stroke,down-regulate the expression of serum NPY,up-regulate the expression of serum BDNF and NGF,and improve the quality of life,with significant effects.
