Abstract：Objective To observe the clinical effect of low frequency neuromuscular stimulation on mild to moderate stress urinary incontinence. Methods All 60 enrolled female patients were enrolled from Harbin First Hospital from October 2019 to May 2021, they were divided into control group (30 cases) and treatment group (30 cases) by random number table method. The control group was treated by simple pelvic floor muscle training, and the treatment group was treated by low frequency neuromuscular stimulation. After 15 days of treatment, the efficacy was evaluated by comparing the surface electromyography and pressure value of type Ⅰmuscle fibre, surface electromyography and pressure value of type Ⅱmuscle fibre, urine leakage volume, frequency of urine leakage, and the degree of influence on patients’ life before and after treatment. Results After treatment, the levels of stress Ⅰ and stress Ⅱ in both groups were higher than those before treatment, while those of the treatment group were higher than those of the control group, the differences were statistically significant (P＜0.05). The levels of electromyography Ⅰ and Ⅱ in both groups were higher than before treatment, while those of the treatment group were higher than those of the control group, and the differences were statistically significant (P＜0.05). After treatment, 1 h pad test urine leakage, average 24 h urine leakage frequency and the score of international consultation on incontinence questionnaire urinary incontinence short form of the two groups were lower than before treatment, while those of the treatment group were lower than those of the control group, and the differences were statistically significant (P＜0.05). Conclusion Low-frequency neuromuscular stimulation can increase the surface electromyography and pressure values of muscle fibers of type I and Ⅱ, inhibit overactivity of detrusor muscle, and improve the clinical symptoms of patients with mild to moderate stress incontinence.
