The study developed and validated a predictive model for predicting pelvic floor muscle weakness in the early postpartum period in primiparous women after vaginal birth[1]. The research included 3514 women, of whom pelvic floor muscle weakness was diagnosed in 25.55% (898 women)[1]. The patients were examined using electromyography of the pelvic floor in the period 42–90 days after delivery[1]. A predictive model was created based on the analysis of maternal and birth factors using logistic regression[1]. The model demonstrated high accuracy with a C-statistic value of 0.866 in the training set and 0.870 in the validation data[1]. This tool can help in the early identification of high-risk women and enable targeted rehabilitation to reduce long-term pelvic floor complications[1].
