Pelvic Floor Muscle Strength: Rethinking Stress Incontinence

For years, the prevailing wisdom in women’s health has been that a strong pelvic floor is the key to preventing stress urinary incontinence (SUI). We’ve been told to do our Kegels, strengthen those muscles, and bid farewell to leaks. But what if the story is more complex? Emerging research is challenging this long-held belief, prompting a shift in how we understand pelvic floor and stress and address SUI.

As mums, our bodies undergo incredible transformations, and the pelvic floor often bears the brunt of these changes. Stress incontinence, the involuntary leakage of urine during activities like coughing, sneezing, or jumping, is a common concern. But are we focusing solely on muscle strength when there are other factors at play?  

The Traditional View: Pelvic Floor Strength as the Primary Solution

Traditionally, healthcare professionals and women’s health advocates have emphasised the importance of pelvic floor muscle strength in preventing and managing SUI. The logic is straightforward: stronger muscles provide better support for the bladder and urethra, preventing leaks during increased abdominal pressure.  

This approach has led to widespread recommendations for pelvic floor muscle training (PFMT), often referred to as Kegel exercises. These exercises involve contracting and relaxing the pelvic floor muscles to improve their strength and endurance.  

Emerging Research: Challenging the Conventional Wisdom

However, recent studies are prompting a re-evaluation of this traditional view. Researchers are exploring whether pelvic floor muscle strength is the sole determinant of continence, or if other factors related to pelvic floor and stress might play an equally critical role.

One pivotal study compared pelvic floor muscle activity during high-impact activities, such as jumping, in women with and without SUI. The goal was to determine if there was a direct correlation between muscle strength and the occurrence of leaks.

The findings of this research have been eye-opening. While pelvic floor muscle function certainly plays a role, the study revealed that it may not be the only factor influencing continence. In fact, the results suggest that other biomechanical and neurological factors may be equally significant.

Beyond Muscle Strength: A Holistic Perspective

This shift in understanding calls for a more holistic approach to SUI. Instead of solely focusing on muscle strength, we need to consider other aspects of pelvic floor function, including:

• Coordination and Timing: The ability of the pelvic floor muscles to contract at the right time and with the appropriate muscle tension is crucial.
• Neurological Control: The nervous system plays a vital role in coordinating pelvic floor muscle function.  
• Connective Tissue Support: The integrity of the connective tissues surrounding the pelvic organs is essential for proper support.
• Biomechanics: Factors such as posture, gait, and overall movement patterns can influence pelvic floor function.  

Practical Implications for Mums

What does this mean for mums experiencing stress urinary incontinence  Here are some key takeaways:

• Don’t Rely Solely on Kegels: While pelvic floor muscle training remains a valuable tool, it’s essential to recognise that it may not be the only solution.
• Seek Comprehensive Assessment: Consult with a women’s health physiotherapist who can assess your pelvic floor function holistically, considering factors beyond muscle strength.
• Explore Functional Exercises: Incorporate functional exercises that mimic real-life movements, such as squats, lunges, and step-ups.
• Focus on Core Stability: Strengthening the core muscles, including the deep abdominals and back muscles, can provide additional support for the pelvic floor.
• Mindful Movement: Pay attention to your posture and movement patterns, and aiming for good alignment. 

At MumSafe, we believe in empowering mums with accurate and up-to-date information. By understanding the evolving research on SUI, you can make informed decisions about your pelvic health and seek the most effective treatment options.

We encourage you to embrace a holistic approach to wellbeing, recognizing that the pelvic floor is part of a complex system. By addressing all aspects of pelvic floor function, you can achieve optimal continence and confidence.
