Prenatal Physiotherapy Guide Oakville | RCP Health
Pregnancy changes everything — including how your body moves, loads, and holds itself together. Over more than two decades of practice, I’ve worked with hundreds of pregnant and postpartum patients at RCP Health Oakville, and what strikes me consistently is how often women minimise their physical symptoms during pregnancy, assuming discomfort is simply part of the experience. Some of it is. But a great deal of it is genuinely treatable, and early physiotherapy input can make a meaningful difference to how you feel throughout pregnancy and how efficiently your body recovers afterwards.
Common Pregnancy-Related Conditions
The three presentations I see most frequently in clinical practice are low back pain, pelvic girdle pain (PGP), and diastasis recti. While they’re often discussed separately, they frequently overlap — and that overlap is clinically important.
Low back pain during pregnancy typically involves the lumbar facet joints and surrounding musculature responding to postural shifts driven by a changing centre of gravity. As the abdomen grows, the lumbar spine often moves into increased extension (an exaggerated inward curve), loading the posterior structures more heavily. What surprises many patients is that the pain often isn’t caused by the baby’s weight alone — it’s the compensation pattern the whole kinetic chain adopts in response that creates the problem.
Pelvic girdle pain is a distinct condition involving the sacroiliac joints and/or the pubic symphysis. A pattern I notice consistently with PGP is that patients describe asymmetrical pain — worse on one side, aggravated by single-leg activities like climbing stairs, rolling in bed, or getting dressed. This asymmetry matters clinically: it often indicates that one side of the pelvis is moving differently than the other, which guides treatment decisions around load management, manual therapy, and targeted stabilisation exercises.
Diastasis recti — the separation of the rectus abdominis along the linea alba — affects a significant proportion of pregnant women, particularly in the third trimester. What many patients don’t realise is that the concern isn’t the separation itself, but the functional capacity of the tissue that remains. A wide diastasis with good tension may function better than a narrow one with poor load transfer. This is why self-diagnosis from online measurements can be misleading, and why a proper clinical assessment of linea alba function changes the rehabilitation approach entirely.
Facts and Figures
A study published in BJOG: An International Journal of Obstetrics and Gynaecology found that pelvic girdle pain affects approximately 20% of pregnant women, with a smaller subset experiencing severe, functionally limiting symptoms. Low back pain is even more prevalent, reported in up to 50% of pregnancies. These figures reflect how common musculoskeletal complications of pregnancy are — and how significant the case for proactive, evidence-based physiotherapy care is for this population.
Safe Exercise Across Each Trimester
Exercise recommendations shift as pregnancy progresses, and what felt effortless in the first trimester may require significant modification by the third. A broad principle holds throughout: we aim to maintain strength and mobility without imposing loads or positions that challenge pelvic floor integrity or cardiovascular tolerance beyond appropriate limits.
- First trimester: Most patients can continue their existing exercise routines with minimal modification. Focus on building a foundation of deep stabiliser activation — transversus abdominis and pelvic floor co-contraction — before symptoms develop.
- Second trimester: As the abdomen grows, supine exercise positions may become less comfortable and are generally avoided after 20 weeks due to potential compression of the inferior vena cava. Side-lying, seated, and standing variations become more central.
- Third trimester: Load management is key. Walking, swimming, stationary cycling, and modified strength work remain appropriate for most patients. High-impact activities and exercises that produce coning or doming at the midline should be discontinued.
- Throughout all trimesters: Breathwork — specifically learning to exhale on exertion and coordinate intra-abdominal pressure with movement — is one of the most practically useful skills I teach pregnant patients, and it directly supports both safe exercise and labour preparation.
- Pelvic floor exercises: These are appropriate throughout pregnancy, but the prescription matters. Overly tight pelvic floors need lengthening and relaxation work as much as strengthening. Blanket advice to “just do Kegels” frequently misses half the clinical picture.
Pelvic Floor Preparation for Birth
Internal pelvic floor assessment during pregnancy — conducted with informed consent and appropriate clinical reasoning — provides information that is genuinely difficult to obtain any other way. I can assess resting tone, the ability to contract and relax voluntarily, and perineal mobility, all of which are directly relevant to labour and delivery outcomes.
In clinical practice, I frequently see patients whose pelvic floors are hypertonic — chronically guarded and unable to fully relax — rather than weak. For these patients, the preparation work looks very different: it emphasises downtraining, lengthening, and perineal massage rather than strengthening. Teaching the body to release on command is arguably more relevant to vaginal birth than strength, and this is a nuance that gets lost when pelvic floor preparation is reduced to contraction-based exercises alone.
Perineal massage, typically introduced from 34–36 weeks, has reasonable evidence supporting its role in reducing perineal trauma in first-time mothers. I teach this directly in clinic at RCP Health Oakville so patients feel confident continuing it at home.
Postnatal Recovery
The postpartum period is not the time to rush back to previous levels of activity — but it is absolutely the time to begin thoughtful, progressive rehabilitation. The six-week clearance from a GP or OB is not a functional assessment; it’s a check that healing has occurred. What it doesn’t tell you is whether your pelvic floor can manage a run, a heavy lift, or a return to higher-intensity training.
Postnatal physiotherapy at RCP Health addresses diastasis recti rehabilitation, pelvic floor restoration, and the gradual reloading of the trunk and lower body. Timelines are individual, symptoms matter more than weeks postpartum, and patients who invest in this phase consistently move into later parenthood with stronger foundations.
