Purpose <p>To investigate the effects of three treatment regimens on postpartum pelvic floor muscle hypertonia.</p> Methods <p>One hundred sixty-five patients with postpartum pelvic floor muscle hypertension treated in a maternal and child health hospital from December 2023 to June 2024 were selected as the research participants. According to the random number table method, they were divided into group A, group B, and group C, with 55 cases in each group. Group A was treated with lifestyle intervention, group B was treated with lifestyle intervention + electrical stimulation and biofeedback therapy, and group C was treated with lifestyle intervention + electrical stimulation and biofeedback + pelvic floor myofascial manipulation. The therapeutic effect, pelvic floor muscle resting potential before and after, and pelvic floor myofascial palpation tenderness visual analog scale score were compared among the three groups.</p> Results <p>The total effective rate of group C (94.3%) was higher than that of group A (37.7%) and group B (87.0%) (<i>P</i> &lt; 0.05). After the intervention, the resting potentials of pelvic floor muscles and the visual analog scale of pelvic floor myofascial palpation tenderness in the three groups were lower than before treatment (<i>P</i> &lt; 0.05), and the reduction in group C was the most significant.</p> Conclusion <p>Lifestyle intervention, electrical stimulation, biofeedback, and pelvic floor myofascial manipulation have the highest efficiency and best therapeutic effect in treating postpartum pelvic floor muscle hypertonia. This scheme can be used optimally and is worthy of clinical promotion.</p>
