MUTU System for Postpartum Incontinence, Diastasis Recti & Sexual Health – What’s The Evidence?

There’s nowhere to hide online. If your product works, if people like what you do, they tell the internet, and if they don’t, well then they definitely tell the internet. In the days of MUTU exercise DVD’s we once got a one-star rating on Amazon that simply stated ‘I haven’t opened it yet.’

Customer survey

To add a little academic detail though, last year we commissioned a survey to ask some very specific questions, based on clinical surveys*, and focussing on three key areas of women’s health:
1. Sexual well being
2. Urinary symptoms
3. Quality of life. 

The survey was sent to a few thousand of our customers who had used MUTU System for 6 weeks or more, and we received 906 complete responses, which were anonymised. This is what they told us:

·   97% of the women who couldn’t successfully locate or engage their pelvic floor muscles before, were able to after using MUTU System

·   92% of women who had experienced bladder symptoms including urinary leakage, saw improvement after using MUTU System

·   88% of women suffering from symptoms of Pelvic Organ Prolapse, reported improvement after using MUTU System

·   89% of women who experienced pain or discomfort during or after sexual intercourse, reported an improvement after doing MUTU System

·   94% of women with diastasis recti (separation of abdominal muscles), reported an improvement after using MUTU System

·   94% of women who used MUTU System felt an improvement in how they felt about their body and what it is able to do.

These results got us noticed by BBC Radio 4 Woman’s Hour, (yes, I actually sat in a studio opposite Dame Jenni Murray *swoon*) and I was also invited to share the results with NHS and private UK midwives in a session at the London Maternity and Midwifery Festival.

We have a medical review of the data from Dr Suruchi Kothari MBBS, BSc(Hons), MRCGP (because hey, we were all in on the academia by this point) which is available below.

When we talk about our physical and mental wellbeing, embarrassing or uncomfortable symptoms, or our self-confidence, we rightly feel vulnerable and in need of reassurance. We want credible guidance, transparent sources and methodology, and honest, impartial reviews from people in the same situation, as well as experts in the field.

This is survey data from our own customer base, not a double-blind controlled clinical study… but it is yet another source of real-world feedback from the customers we serve every day, and which we are continually working with medical professionals to expand.

Pelvic Floor Muscle Exercises and Function: A review of an online modality of training


The pelvic floor sits at the bottom of our pelvis. It is an important and highly integrated structure consisting of muscles, ligaments and connective tissue. The pelvic floor has a few key functions:

Maintaining continence – the pelvic floor muscles (PFM) form sphincters around the urethra, vagina and rectum enabling voluntary control of these orifices. This maintains urinary and faecal continence.14

Sexual Function – the muscles of the pelvic floor help maintain blood flow to the vaginal region, by contracting rhythmically to enhance sexual pleasure.13

Support – the pelvic floor supports the pelvic organs e.g. bladder, uterus and colon, and keeps these organs in place.14

Pelvic and Spinal Stabilisation – the transversus abdominis, pelvic floor, deep multifidus and diaphragm form a muscular cylinder, which supports the spine and the pelvis; these muscles work together as a unit to ensure and maintain trunk stability.11,12


Childbirth and pregnancy can increase the risk of weakening and injury to the pelvic floor muscles (PFMs) and the perineum1. Approximately half of postpartum women may lose some of the supporting function of the PFMs after delivery1. This weakness can lead to urinary incontinence, faecal incontinence, prolapse of the pelvic floor organs and sexual problems.

Although the exact mechanisms of these physiological changes have yet to be fully established. The increased levels of hormones, which prepare the body for pregnancy and delivery, allow the dense structures to soften and increase the pelvic floor laxity. 

As the uterus grows during pregnancy, the pelvic organs are pushed downwards. Resulting in an increase in intra-abdominal pressure; exposing the pelvic floor muscles to stresses and strain4. The hormones and physical changes, as well as the increased pressure on the pelvic floor, play an important role in the development of Pelvic Floor Dysfunction 4,5,6,7.

A systemic review which included over fifteen studies and over six thousand women revealed pelvic floor muscle training reduced urinary incontinence in pregnant women and urinary and faecal incontinence in postpartum women8. Provided there was no serious degree of uterine prolapse and the exercises were followed accurately.8

Prenatal pelvic floor muscle training (PFMT) can decrease symptoms of urinary incontinence9 and improve muscle coordination and produce strong and flexible muscles during labour10. Postnatal PFMT women can effectively reduce the symptoms of pelvic floor dysfunction.8 Furthermore, results of a study looking at pelvic function in nulliparous pregnant women demonstrated the thickness and strength of the pelvic floor muscles in continent pregnant women were found to be higher than in those who suffered from incontinence3.

Mothers to be are most frequently advised to conduct PFMT during the late stage of pregnancy and the early postnatal phase. If PFMT is delayed it is less likely to reduce urinary incontinence.8, 15,16 Guidelines from the National Institute for Health and Care Excellence recommend training pelvic floor muscles as the first point of treatment for women with urinary incontinence and pelvic organ prolapse.19

Currently, PFMT is offered in a range of formats; in person, via internet-based solutions and mobile applications, using devices, through verbal or written instructions provided by health care professionals.

However, performing pelvic floor exercises is not easy; studies have demonstrated that 70% of women were unable to accurately locate and contract their pelvic floor muscles.18 A shortage of PMFT trained physiotherapists, poor attendance at classes and unavailability can add to the challenge in delivering effective in-person PFMT.15 Research has also demonstrated there is no additional benefit in combining PFMT with biofeedback, vaginal cones or electrical simulations.20,21

Thus, based on the literature pelvic floor dysfunction interventions need to be started early8, 15,16, must include the provision of effective instructions, must be widely accessible17 and not require a highly trained expert17.


Aim: To assess the efficacy of an online exercise portal which provides the provision of accurate and effective instructions is widely accessible and can be conducted from the comfort of an individual’s home.

MUTU System is an online exercise programme for mother’s and women with low risk pregnancies. The programme includes real time videos, which include MUTU core and pelvic rehabilitation techniques.

To study the impact of this programme a questionnaire was constructed to gain feedback on five key areas based on existing clinical questionnaires. Key areas included: Ability to accurately identify the pelvic floor; Bladder symptoms including urinary leakage; Symptoms of pelvic organ prolapse; Sexual well being; Quality of life including body confidence; Presence of diastasis recti (separation of abdominal muscles)

Design & survey

Two modes of responses were included as relevant to the question including;

  1. YES/NO questions (polar questions) were used to identify existing symptomatology
  2. A Likert scale ranging from ‘very much improved’ to ‘worsened’ was utilised to measure the change in individual symptoms as a result of conducting the MUTU programme.

This survey was sent to individuals who had used MUTU System for 6 weeks for more and the anonymised results were collated.


906 respondents fully completed the questionnaire.

The responses are collated below the relevant category:

I.    Ability to accurately identify the pelvic floor
97% of women who couldn’t successfully locate or engage their pelvic floor muscles previously, were able to after using MUTU System

II.    Bladder symptoms including urinary leakage
92% of women who had experience bladder symptoms including urinary leakage saw improvement after using MUTU System

III.    Symptoms of pelvic organ prolapse
88% of women suffering from symptoms of Pelvic Organ Prolapse reported improvement after using MUTU System

IV.    Sexual well being
89% of women who experienced pain or discomfort during or after sexual intercourse reported an improvement after doing MUTU System

 V.    Quality of life including body confidence
94% of women who used MUTU System felt an improvement in how they felt about their body and what it is able to do.

 VI.    Presence of diastasis recti (separation of abdominal muscles)
94% of women with diastasis recti (separation of abdominal muscles) reported an improvement after using MUTU System.
