〔Abstract〕 Objective To explore the effect of pelvic floor surface electromyography combined with low-frequency electrical pulse technology on uterine involution after cesarean section. Methods From March 2018 to September 2019, 60 cases of parturients after cesarean section admitted to the Second People's Hospital of Jiedong District, Jieyang City were selected and divided into observation group and control group according to the random number table method, with 30 cases in each group.The control group was treated with low-frequency electric pulse technique, and the observation group was combined with pelvic floor surface electromyography on the basis of the control group. After 2 weeks of treatment, the uterine involution, clinical features and sign scores, and quality of life scores of the two groups were observed and compared. Results After treatment, the effective rate of maternal treatment in the observation group was 96.67%, which was much higher than 80.00% in the control group. The difference was statistically significant (P < 0.05); The scores of clinical features and physical signs of the observation group were lower than those of the control group, and the differences were statistically significant (P < 0.05); Before treatment, there was no statistically significant difference between the two groups of maternal life quality scores (P > 0.05); After treatment, the quality of life scores of the two groups were improved, and the scores of the observation group was higher than those of the control group, the differences were statistically significant (P < 0.05). Conclusion The pelvic floor surface electromyography combined with low-frequency electrical pulse technology can promote the involution of the uterus of the parturient after cesarean section, improve the clinical symptoms and signs, and improve the quality of life.
