🚨Pelvic health physios🚨
This is a relatively niche one, but I’d really like to use your collective brains as a sounding board.
This post came from a conversation with a PT who had referred her asymptomatic pregnant client to a pelvic health physio, primarily to check that she was activating her pelvic floor correctly.
During the assessment, the client had a measurement taken of her perineum. I don’t know the exact specifics of what was measured, but the client understood from this measurement that she was at a higher risk of perineal tearing during birth and was subsequently advised to stop lifting weights during pregnancy because of this.
I’m acutely aware that this is second-hand information. We all know that what we communicate as clinicians and what a patient takes away from a consultation aren’t always the same thing, so there may well be more nuance to the original conversation.
Nonetheless, the client’s take-home message was that she was at high risk of tearing and that lifting weights could increase that risk. She left the appointment scared to lift.
I don’t routinely take perineal measurements as part of my antenatal pelvic floor assessments, so this sent me down a bit of a rabbit hole:
👉🏼What exactly are we measuring?
👉🏼How well does it predict perineal trauma?
👉🏼Does identifying someone as potentially “higher risk” actually change our management?
👉🏼And, importantly, what are the potential unintended consequences of communicating that risk?
As you’ll see from the carousel, I’m not presenting this as “this measurement is wrong and nobody should be doing it.” It’s really me hashing out my own thoughts after looking at the evidence and having conversations with other pelvic health physios.
So pelvic health physios, I’d genuinely love to hear your clinical reasoning.
Do you take perineal measurements antenatally? If so, what do you measure, how do you use that information, and does it change the advice you give?
And if you don’t measure — why not?
Would love a nerdy pelvic health discussion on this one 👇
