Abstract:

Objective： To explore the effect of yiqi xingnao yin（YQXN） combined with functional exercise guided by VR technology on elderly patients with lower limb dysfunction after ischemic stroke.Methods： A total of 90 elderly patients with lower limb dysfunction after ischemic stroke treated in our hospital from July 2017 to July 2022 were selected. The patients were randomized divided into 3 groups， namely， yiqi xingnao yin group （Group A）， yiqi xingnao yin combined with VR-guided functional exercise group （Group B） and VR-guided functional exercise group （Group C）. The patients in group A were treated with yiqi xingnao yin （20 mL·d^-1， tid） while group B were given the combined treatment of yiqi xingnao yin （20 mL·d^-1， tid） combined with VR guided functional exercises （once a day）， and the patients in group C received VR-guided functional exercise therapy once a day. After 3 months of treatment， the clinical efficacy of the three groups was evaluated， and the FMMS score， lower limb muscle strength， degree of neurological deficit， motor ability， daily living ability， and changes in blood lipids of patients in each group were compared before and after treatment.Results： The treatment efficacy of the three groups was 78.57%， 89.66% and 67.80%， respectively， all of which demonstrated the capacity to enhance lower limb functionality in ischemic stroke patients， and there was no statistial difference between the groups. FMMS scores were significantly higher and lower limb muscle strength scores were lower in all groups after treatment compared to pre-treatment （P<0.05）， and FMMS scores were significantly higher and lower limb muscle strength score was lower in group B after treatment （P<0.05）. NIHSS scores and CSS scores were lower in all groups after treatment than before treatment （P<0.05）. The NIHSS scores and CSS scores of group B patients decreased more significantly after treatment （P<0.05）. There was no significant difference in the scores of the BI index among the three groups of patients after the treatment. Compared with pre-treatment， the levels of CHO， TG， and LDL of patients in group A and group B reduced after treatment （P<0.05） and there were statistical difference with those in group C （P<0.05）， and there was no significant difference in the levels of HDL between the groups.Conclusion： Yiqi xingnao yin combined with VR guided functional exercise can improve the motor ability of elderly patients with lower limb dysfunction after ischemic stroke， reduce levels of CHO， TG， and LDL in the body， and improve the patient's ability of daily life.
