The effect of Tubigrip and a rigid belt on rectus abdominus diastasis immediately postpartum: A randomised clinical trial.

BACKGROUND: Rectus abdominis (RA) diastasis is a risk factor for abdominal muscle dysfunction and reduced quality of life postpartum. It is thought that supplementary abdominal supports might reduce the diastasis. However, there is limited research assessing the efficacy of abdominal supports/binding. OBJECTIVE: To determine the effects of Tubigrip and a rigid abdominal belt in reducing RA diastasis in the first eight weeks postpartum. DESIGN: Randomised clinical trial. METHODS: 62 women undertook ultrasound imaging to measure their RA diastasis prior to and after an eight week intervention wearing either Tubigrip or a rigid abdominal belt. Data analyses involved repeated measures ANOVA and correlational methods. RESULTS: The RA diastasis reduced by 46% from a mean 4.6 cm-2.5 cm over the eight week intervention period with no significant difference (p > 0.05) across groups. Women wore the Tubigrip for a significantly (p < 0.05) longer number of hours (Median: 278) compared to those in the belt group (Median: 81 h). The length of time that women wore Tubigrip or the belt was not associated with the percentage reduction in the RA diastasis (p > 0.05). There was no significant difference in the diastasis across vaginal and Caesarean section deliveries at baseline. There was a significant difference (p < 0.05) in the percent reduction of the RA diastasis across deliveries post-intervention (vaginal delivery mean: 48% vs C-section: 40%). CONCLUSION: There was no difference across groups post-intervention in the RA diastasis, and it is questionable whether either support improves upon that associated with natural healing alone.

Exercises, Tubigrip and taping: can they reduce rectus abdominis diastasis measured three weeks post-partum?

BACKGROUND: Rectus abdominis diastasis is regarded as a risk factor for abdominal muscle dysfunction and reduced quality of life postpartum. It is thought that specific exercises and additional physical support might reduce the diastasis, with a need to establish efficacy in doing so. OBJECTIVES: Determine the effect of four abdominal exercises as well as Tubigrip or taping in reducing rectus abdominis diastases three weeks postpartum. DESIGN: Cross-sectional repeated measures comparison. METHODS: 32 women undertook a single session of ultrasound imaging. Ultrasound measurements of inter-rectus distance were taken at rest and during: 1) crook lying abdominal "drawing in" exercise; 2) crook lying trunk curl-up; 3) early Sahrmann level leg raise; 4) McGill side lying plank. The curl-up and abdominal "drawing in" exercises were assessed under two further conditions: a) wearing Tubigrip, b) taping across the diastasis. Data analyses involved repeated measures ANOVA. RESULTS: At rest the mean inter-rectus distance above and below the umbilicus was 3.5 cm (SD:1.1) and 2.6 cm (SD:1.2) respectively. A significant decrease (19%, p < 0.05) was observed at both measurement points during the curl-up exercise. No other exercises elicited a significant difference compared to resting. At rest, wearing Tubigrip reduced the inter-rectus distance (7%, p < 0.05). During exercise, there was no additional change in the inter-rectus distance (p > 0.05) with supports. CONCLUSION: The curl-up exercise was most effective in reducing inter-rectus distance. As no exercises invoked an increase in the rectus diastasis, they could not be regarded as potentially detrimental. Tubigrip and taping did not add to the effects of these exercises.

A self-report questionnaire for pregnancy-related symphyseal pain.

BACKGROUND: Symphyseal pain (SP) experienced during pregnancy is a common condition that can negatively influence function and wellbeing. Despite its adverse impact on quality of life, standardised diagnostic criteria for SP as a distinct type of pelvic girdle pain (PGP) are lacking. OBJECTIVES: To develop a reliable self-administered instrument that could differentiate SP from posterior PGP in pregnant women, and ultimately be used for epidemiological or clinical purposes. METHOD: Qualitative data from 17 women (four focus groups) were used to develop a questionnaire. The questionnaire was tested against physical therapy diagnoses based on clinical assessment in 122 pregnant women with SP (n = 41), posterior PGP (n = 41) or no PGP (n = 40); 30 women repeated the questionnaire a day later to assess reliability. Multinomial logistic regression models were used to assess the performance of candidate items in distinguishing between the groups. RESULTS/FINDINGS: The single questionnaire item relating to location of worst pain (diagrammatic form) is useful for differentiating SP from posterior PGP and individuals with no PGP. The worst pain location question with the addition of the Pelvic Girdle Questionnaire provides a measure of "SP with impact", and is the best combination for distinguishing SP and posterior PGP. Test-retest reliability scores were excellent. CONCLUSION: These findings provide new opportunities for diagnosing pregnancy-related SP, and highlight questionnaire items which best differentiate SP from posterior PGP. These items could be used in future epidemiological research, and in clinical settings as a quick, effective screening tool.

Management of symphysis pubis dysfunction during pregnancy using exercise and pelvic support belts.

BACKGROUND AND PURPOSE: Symphysis pubis pain is a significant problem for some pregnant women. The purpose of this study was to investigate the effects of exercise, advice, and pelvic support belts on the management of symphysis pubis dysfunction during pregnancy. SUBJECTS: Ninety pregnant women with symphysis pubis dysfunction were randomly assigned to 3 treatment groups. METHODS: A randomized masked prospective experimental clinical trial was conducted. Specific muscle strengthening exercises and advice concerning appropriate methods for performing activities of daily living were given to the 3 groups, and 2 of the groups were given either a rigid pelvic support belt or a nonrigid pelvic support belt. The dependent variables, which were measured before and after the intervention, were a Roland-Morris Questionnaire score, a Patient-Specific Functional Scale score, and a pain score (101-point numerical rating score). RESULTS: After the intervention, there was a significant reduction in the Roland-Morris Questionnaire score, the Patient-Specific Functional Scale score, and the average and worst pain scores in all groups. With the exception of average pain, there were no significant differences between groups for the other measures. DISCUSSION AND CONCLUSION: The findings indicate that the use of either a rigid or a nonrigid pelvic support belt did not add to the effects provided by exercise and advice.
