Outcome:

Takeup rate of AI-based education and face-to-face midwife instruction in perineal massage practice with compliance of at least 2 times per week, and 10 minutes each time. The take-up rate is defined as follows: Participants are instructed to begin perineal massage starting from the 34th week of pregnancy, performing the massage twice a week for 10 minutes per session. A completed massage session in a given week is considered one take-up. Since the period from the 34th to the 38th week of gesta

Outcome:

To be assessed the perineal pain will be measured using the Visual Analogue Scale (VAS). To record the wound healing will be assessed on postpartum Day 1 and Day 2 using the REEDA scale, which evaluates five parameters: redness, edema, ecchymosis, discharge, and approximation of wound edges. Marital satisfaction questionnaire and Female Sexual Function Index will assess the marital relationships per discussed. In addition, pelvic floor function will be assessed through validated questionnaires

随机方法(请说明由何人用什么方法产生随机序列):

在产前随访招募期间以及孕34周或之后,将进行随机化操作。妇女们将获得一个密封的、非透明的信封。通过置换区组随机化,参与者将被分配到 i) 面对面教学组 或 ii) 人工智能教学组。在每个分层内,妇女将使用大小为4的区组以 1:1 的比例随机分配到面对面教学组或人工智能教学组;参与者将被随机分为两组:i) 面对面教学组作为对照组,以及 ii) 人工智能教学组作为干预组。鉴于干预措施的性质,这是一种单盲设计,分配的分组结果将对负责收集和分析数据的研究者设盲,但对参与的妇女不设盲。

Randomization Procedure (please state who generates the random number sequence and by what method):

Upon antenatal follow up for recruitment and the at 34 weeks or beyond, randomization will be performed. The women will obtain a sealed, non-opaque envelop. Randomization to either i) face-to-face teaching group or ii) AI teaching group will be accomplished by permuted-block randomization. Within each stratum, women will be randomly assigned to face-to-face teaching group or AI teaching group in a ratio of 1:1 using a block size of 4. Participants will be randomized into two groups: i) face-to-face teaching as a control group and ii) AI teaching group as the interventional group.

Blinding:

Due to the nature of intervention, this is a single blinded design with the allocated arm assignment will be blinded to the investigators who collect and analysis the data but who will not blinded to women.
