| Objective: To explore the influences of hyperbaric oxygen combined with electromyography biofeedback on cerebral oxygen metabolism, nerve function and limb function during the recovery period of acute cerebral infarction. Methods: A total of 106 patients who were treated in our hospital from January 2021 to December 2022 were grouped into control group (53 cases) and combined group (53 cases) according to random sampling method. Both groups were given conventional treatment according to the patients' conditions. The control group was treated with electromyographic biofeedback therapy on the basis of conventional treatment for acute cerebral infarction, and the combined group was treated with hyperbaric oxygen combined with myoelectric biofeedback on the basis of conventional treatment. The clinical efficacy, brain oxygen metabolism index [CaO2, D(a-jy)O2, CERO2] level, National Institute of Health stroke scale (NIHSS) score, Fugl-Meyer rating scale (FMA) score and adverse reaction rate were compared between the two groups before and after treatment. Results: The total effective rate of the combined group was 90.57%, which was obviously higher than 79.25% of the control group (P<0.05); the total incidence of adverse reactions in the combined group was 11.32%, the total incidence of adverse reactions in the control group was 7.55%, and there was no obvious difference between the groups (P>0.05); there was no obvious difference in the levels of CaO2, D(a-jy)O2 and CERO2 between the two groups before treatment (P>0.05); after treatment, the levels of CaO2, D(a-jy)O2 and CERO2 in the two groups decreased obviously (P<0.05), the decrease degrees of the combined group were obviously higher than those of the control group (P<0.05), while there was no obvious difference in CaO2 between the two groups after treatment (P>0.05); there was no obvious difference in NIHSS score between the two groups before treatment (P>0.05), after treatment, the NIHSS score of the two groups decreased obviously (P<0.05), the decrease of the study group was more obvious than that of the control group (P<0.05); there was no obvious difference in FMA scores between the two groups before treatment (P>0.05), after treatment, the FMA score of the two groups increased obviously (P<0.05), the degree of increase in the study group was higher than that in the control group (P<0.05). Conclusion: Hyperbaric oxygen combined with myoelectric biofeedback has significant efficacy in the treatment of patients in the convalescent stage of acute cerebral infarction, which can adjust the level of cerebral oxygen metabolism, improve nerve defect function, effectively promote limb recovery, and has high safety. |
