Abstract:Objective To explore the application value of fascial release technique combined with Waff core exercise in postpartum rectus abdominis diastasis.Methods A total of 96 parturients with rectus abdominis diastasis who delivered at Huai'an Maternal and Child Health Hospital from June 2023 to January 2024 were enrolled in this study. Using a blinded method, the participants were randomly allocated by computer-generated sequence into two groups: an observation group and a control group, with 48 cases in each group. The control group received Waff core exercise therapy, while the observation group received combined fascial release manual therapy on the basis of the control group. The rehabilitation treatment lasts for 8 weeks. Compare the inter rectus abdominis distance (IRD), rectus abdominis thickness, waist circumference, urinary incontinence symptoms, uterine prolapse symptoms, lower back pain, emotional state, and quality of life scores between two groups.Results The differences in IRD at 5.0 cm above the umbilicus, umbilical IRD, and IRD at 5.0 cm below the umbilicus before and after treatment were significantly greater in the observation group than in the control group (P < 0.05). After treatment, the thickness of rectus abdominis in the observation group was larger than that in the control group, and the waist circumference was smaller than that in the control group (P < 0.05). Significantly greater differences in urinary incontinence and uterine prolapse symptom scores before and after treatment were observed in the observation group than in the control group (P < 0.05). The difference in low back pain symptom scores before and after treatment was shown to be significantly higher in the observation group than in the control group (P < 0.05). The differences in HAMA scores, HAMD scores, and SF-36 scores before and after treatment were all demonstrated to be significantly greater in the observation group compared to the control group (P < 0.05).Conclusion The combination of Waff core exercise and fascial release technique in the treatment of postpartum rectus abdominis diastasis can help reduce the patient's IRD, promote the recovery of rectus abdominis muscle, alleviate symptoms such as urinary incontinence, uterine prolapse, and lower back pain.
