Exploring the efficacy evaluation of electrophysiological rehabilitation services in endometrial repair after induced abortion, providing scientific basis for medical institutions and government post abortion care decision-making. This study is a multicenter randomized controlled intervention study. The main endpoint of the study was the measurement of endometrial thickness by transvaginal ultrasound on days 21-23 after abortion. Secondary study endpoint: 1. Postoperative uterine contraction pain; 2. Patient satisfaction; 3. Menstrual recurrence time; 4. Changes in menstrual flow for two consecutive periods after surgery; 5. The duration of two consecutive menstrual periods after surgery.

On the basis of treatment in the control group, postoperative electrophysiological rehabilitation services were started for 30 minutes each time, once a day, for 6 consecutive days as one course of treatment, for a total of one course of treatment. The patch is located at the projection site of the lower abdomen uterus as shown in the figure, simulating bioelectric stimulation parameters: biphasic pulse current, frequency 2Hz, pulse width 3ms. Simultaneously conducting family health education, including but not limited to: 1. Guidance on postoperative physical recovery after abortion: provide advice on postoperative care, nutrition, activity, and personal hygiene; 2. Introduction to contraceptive methods: Introduce the advantages and disadvantages of various contraceptive methods, and help patients choose the most suitable contraceptive method for themselves; 3. Other related health education: including fertility planning and the best time to conceive again.

Transvaginal ultrasound examination is used to measure the thickness of the endometrium.
On the 21st to 23rd day after abortion, vaginal ultrasound was used to measure endometrial thickness.
Time frame: On the 21st to 23rd day after abortion.
Postoperative uterine contraction pain
The degree of postoperative pain was evaluated using the Visual Analogue Scale (VAS) scoring method. A horizontal line of 10 cm in length was drawn, with the two ends representing 0 and 10 respectively. 0 indicated no pain, and 10 represented the most unbearable pain that could be imagined. Patients were asked to select the corresponding number based on their postoperative pain sensation to describe the intensity of their subjective pain. The time for postoperative pain assessment was as follows: for the experimental group, the VAS pain score was evaluated before treatment on the second day after surgery and after one session of bioelectrical stimulation treatment; for the control group, the VAS pain score was evaluated only once on the second day after surgery.
Time frame: One week after surgery
Patient satisfaction
Survey the satisfaction levels of patients in the control group and intervention group, specifically covering sub item satisfaction evaluations of biomimetic electrical stimulation treatment, doctor attitude, abortion process, and extended home rehabilitation services. Each item is divided into five levels: very satisfied, satisfied, average, dissatisfied, and very dissatisfied. In addition, the overall satisfaction of the above four items will be comprehensively evaluated.
Time frame: 3 months after surgery
Menstrual recurrence time
Observe the time of menstrual recurrence in two groups after surgery, that is, the interval between the completion of induced abortion and the recurrence of menstruation in the subjects.
Time frame: 3 months after surgery
Changes in menstrual flow for two consecutive periods after surgery
Understand the postoperative menstrual flow of the research subjects for two consecutive periods. The specific reference criteria are: compared with the preoperative menstrual flow, it is divided into five levels: much more, slightly more, similar, slightly less, and much less.
Time frame: 3 months after surgery
Duration of two consecutive menstrual periods after surgery
By conducting a 3-month online follow-up on the control group and intervention group, we aim to understand the duration of continuous menstruation in the study subjects after surgery.
Time frame: 3 months after surgery
