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

Abstract

BackgroundRectus 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. ObjectivesDetermine the effect of four abdominal exercises as well as Tubigrip or taping in reducing rectus abdominis diastases three weeks postpartum. DesignCross-sectional repeated measures comparison. Methods32 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. ResultsAt 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. ConclusionThe 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.
