Objective: To explore the effect of bionic electrical stimulation synchronized with intrachamber hyperbaric oxygen on patients with cerebral infarction in convalescent period.

Methods: From August 1, 2016 to October 30, 2017, 68 patients with cerebral infarction in convalescent period who received rehabilitation treatment in the Department of Rehabilitation Medicine of Shanghai Eighth People’s Hospital met the criteria for case selection. These 68 patients were randomly divided into study group (34 cases) and control group (34 cases) treated with hyperbaric oxygen synchronized with intrachamber bionic electrical stimulation and hyperbaric oxygen combined with bionic electrical stimulation nonsynchronously, respectively. Neurological impairment and activity of daily living were assessed by the National Institute of Health Stroke Scale (NIHSS) and modified Barthel index before treatment, 20 days after the start of treatment, and 1 month and 3 months after the end of treatment. The clinical effective rates of the 2 groups were evaluated 20 days after the start of treatment and 1 month and 3 months after the end of treatment.

Results: Thirty-three patients in the study group and 31 patients in the control group were included in the final statistical analysis. Before treatment, there was no significant difference in the NIHSS score and the modified Barthel index between the 2 groups (P > 0.05). At 20 days after the start of treatment and 1 month and 3 months after the end of treatment, the NIHSS scores of the two groups were significantly lower and the modified Barthel index were significantly higher than those before treatment (P < 0.05); the NIHSS scores of the study group were significantly lower than those of the control group (P < 0.05), and the modified Barthel index were significantly higher than those of the control group (P < 0.05); the clinical effective rate of the study group was also significantly higher than that of the control group (P < 0.05).

Conclusion: Hyperbaric oxygen synchronized with intrachamber bionic electrical stimulation and hyperbaric oxygen combined with bionic electrical stimulation nonsynchronously can both improve the functional impairment of the patients with cerebral infarction in convalescent period, especially hyperbaric oxygen synchronized with intracabin bionic electrical stimulation is more effective.
