Objective To observe the application of interaction model of client health behavior（IMCHB） in the rehabilitation of pelvic floor function in patients with severe uterine prolapse treated with hysterectomy combined with pelvic floor reconstruction.Methods Seventy-four patients who underwent hysterectomy combined with pelvic floor reconstruction for severe uterine prolapse in a hospital in Luoyang City from March 2017 to July 2020 were selected as subjects and assigned to control and observation groups using the random number table method

with 37 participants in each group.Patients in the control group received conventional health education and rehabilitation training interventions

and patients in the observation group received IMCHB rehabilitation training interventions after the same conventional interventions in the control group

and subjects in both groups received continuous interventions for 6 months.The recovery of pelvic floor function [Pelvic Floor Impact Questionnaire short-7（PFIQ-7）]

psychological state [Kessler Psychological Distress Scale（K10）]

and sexual life [Female Sexual Function Index（FSFI）] were compared between the two groups before intervention and at 3 and 6 months after the intervention.The compliance of pelvic floor rehabilitation training was compared between the groups at 3 and 6 months of intervention.Results The PFIQ-7 and K10 scores of the observation group were lower than those of the control group at 3 and 6 months of intervention;the scores of sexual desire

dyspareunia

active sexual arousal

orgasm

vaginal lubrication during sexual activity

sexual life satisfaction and the FSFI scores were higher than those in the control group

and the differences were statistically significant（P<0.05）.The pelvic floor rehabilitation training compliance of the observation group was higher than that of the control group at 3 and 6 months of intervention

and the differences were statistically significant（P<0.05）.Conclusion The IMCHB rehabilitation intervention can effectively improve the compliance of pelvic floor rehabilitation training in patients with hysterectomy combined with pelvic floor reconstruction

reduce the level of psychological distress

and enhance the rehabilitation effect of pelvic floor function.
