This study examined birth outcomes in Czech primiparous women giving birth spontaneously vaginally at term, head down, and compared differences between women exercising with Aniball and those who did not.
The study concluded that Aniball helps prevent perineal injuries. It confirmed that it is safe - its use does not increase the risk of pelvic floor damage and does not cause urogynecological problems later in life.
There was no difference in the incidence of pelvic floor injury (levator ani muscle avulsion) between the two groups, dispelling concerns raised by opponents that Aniball disrupts the integrity of the pelvic floor and impairs a woman's quality of life after childbirth.
More frequent exercise does not lead to a further reduction in the number of birth injuries or an improvement in their spectrum. On the contrary, less frequent exercise (every other day) appears to be more beneficial.
The most common maximum balloon circumference was 25 cm - which confirms that it is not desirable to inflate the balloon more. The goal of the training is to practice pelvic floor relaxation and not to achieve the largest possible balloon circumference.
Exercising women did not report a decrease in quality of life (in terms of incontinence or sexual dysfunction) after childbirth. On the contrary, stress incontinence and a deterioration in the quality of the lovemaking experience after childbirth were reported more by non-exercising women: stress incontinence (p = 0.066) and sexual dysfunction (p = 0.14).
Furthermore, analysis of reasons for women dropping out of the study after delivery revealed a non-significant reduction in vaginal extractions in women who exercised (6.8% vs. 17.3%, p = 0.0895). This interesting side finding could prompt further research into the potential benefits of balloon use?
