Efficacy of electro-acupuncture in postpartum with diastasis recti abdominis: A randomized controlled clinical trial

Abstract

BackgroundElectro-acupuncture (EA) has promising effects on diastasis rectus abdominis (DRA), defined as a separation of the two muscle bellies of rectus abdominis. To study, there is scant knowledge or scarce high-quality evidence.ObjectiveWe aimed to evaluate the long-term efficacy and safety of EA in treating DRA during postpartum. It was assumed that the improvement of DRA was more obvious in the EA group than in the control group.DesignRandomized, controlled, blinded trial (Clinical Trial Registration: ChiCTR2100041891).SettingHangzhou Hospital of Traditional Chinese Medicine in China.ParticipantsFemales aged 20–45 years without a past medical history of pathological rectus abdominal dissection were recruited from DRA inclusion criteria from 42 days to 1 year postpartum.Intervention110 participants were randomly assigned in a 1:1 ratio to a control group with no EA intervention (n = 55), and EA group (n = 55). The EA group received ten sessions of EA combined with physical exercise or only physical exercise over 2 weeks with a 26-week follow-up after treatment.MeasurementsOutcomes were assessed at baseline, week 2, and week 26. The primary outcome was the change of the inter recti distance (IRD) and electromyographic evaluation of the pelvic floor. Secondary outcomes included elasticity of linea alba (LA), paraumbilical subcutaneous adipose tissue (SAT) measurement, body mass index (BMI), percentage body fat (F%), dyspepsia symptoms, menstrual symptoms, quality of life (QoL), pain performance of patients with lower back pain, postnatal depression symptoms (PDS), postpartum self-image, and DRA-related symptom assessment including urine leakage, frequency, and urgency, constipation, sexual dysfunction, and chronic pelvic pain.ResultsA total of 110 maternal (55 in each group) were recruited. The mean difference in IRD from baseline to week 2 and week 26 in all states of the two groups were reduced compared with those before treatment, with statistical significance (P < 0.05). The mean of IRD at the horizontal line of the umbilicus in the end-expiratory state was smaller in the EA group than in the control group, but the difference was not statistically significant (P > 0.05) at week 2. The mean of IRD at the horizontal line of the umbilicus in head-up and flexed knee state was smaller in the EA group than in the control group, and the difference was statistically significant (P < 0.05) at week 26. Five (9.1%) and thirteen (23.64%) adverse events were reported in EA and control groups, respectively. No serious adverse events were reported.LimitationThe frequency intensity of EA parameters was selected between 4 and 6 because of individual tolerance differences.ConclusionEA is an effective approach to improve IRD, electromyographic evaluation of the pelvic floor, BMI, the elasticity of LA, paraumbilical SAT, and symptoms of DRA, with durable effects at 26 weeks after treatment.Primary funding sourceThe Construction Fund of Medical Key Disciplines of Hangzhou (Project Number: OO20200097), Hangzhou Medical and Health Science and Technology Project No. A20200483, and Zhejiang Traditional Chinese Medicine Science and Technology Plan Project (Project Number: 2021ZQ065).Clinical trial registrationhttp://www.chictr.org.cn/index.aspx, identifier: ChiCTR2100041891.

Therapeutic effect of manual massage on early postpartum rectus abdominis separation and postpartum depression

“…The changes in abdominal appearance caused by postpartum DRA can have varying degrees of impact on the emotions of postpartum women, which mainly manifest as lack of interest, low emotions, and depression, among others[ 19 ]. This may be related to contemporary women’s pursuit of an ideal body shape.…”

Risk Factors and Patient-Reported Outcomes in Chinese Women with Postpartum Diastasis Recti Abdominis: An Observational Study

“…Women who visited the Postpartum Clinic at the Department of Acupuncture and Rehabilitation, Hangzhou Hospital of Traditional Chinese Medicine, Dingqiao District, between May 29 th , 2020 and December 9 th , 2022, were eligible for enrollment in this study provided they met the following inclusion criteria: 10 (1) they were between the ages of 20 and 55 years; (2) they had given birth at least 42 days prior to enrollment; and (3) they were not currently undergoing and had not previously undergone treatment for DRA.…”

“…The exclusion criteria 10 were suspected or diagnosed severe spinal lesions or neurological injuries (such as bone fractures, metastases, inflammatory or infectious diseases, cauda equina syndrome, and widespread neurological disorder); motor contraindications; and severe infectious diseases (such as severe cardiovascular disease and cancer).…”

Differentially expressed genes of esophageal tissue in male acute and chronic sleep deprivation mice

“…Gastroesophageal reflux disease (GERD) is a chronic disease characterized by typical symptoms, including recurrent and troublesome heartburn and acid regurgitation 1 . In addition, some atypical symptoms seriously plague patients, including difficulty swallowing, throat discomfort, chest pain, dyspepsia, postprandial fullness, early satiation and epigastric pain 2 . Gastroesophageal reflux is strongly associated with the development of multiple esophageal diseases, including Barrett's esophagus (BE) and esophageal carcinoma (ESCA).…”
