Curb Walking During Pregnancy: Does It Actually Induce Labor?
If you’re approaching your due date, you’ve probably heard of curb walking to induce labor. Maybe a friend recommended it, your provider mentioned it, or you’ve seen videos online of pregnant women walking up and down curbs in an attempt to get labor started.
But does curb walking actually work?
The short answer: we don't currently have good evidence that curb walking itself induces labor. However, there are some interesting reasons why it has become a popular labor-preparation technique.
What Is Curb Walking?
Curb walking is exactly what it sounds like: walking with one foot on a curb or other slightly elevated surface while the opposite foot remains on the ground.
This creates an asymmetrical walking pattern, meaning each side of your body is moving and loading slightly differently. From a physical therapy perspective, this creates different movement through the hips and pelvis compared with walking on a level surface.
You may hear people describe curb walking as a way to “open the pelvis.” That phrase can be misleading. Your pelvis isn't simply opening and closing with each step. Instead, there is subtle movement through the pelvis, hips, sacrum, and surrounding muscles and connective tissues as you move.
Does Curb Walking Induce Labor?
This is where we need to separate what we think might happen from what research has actually demonstrated.
There is currently NO strong clinical research showing that curb walking specifically causes labor to begin.
There are theories about why it might be helpful. The asymmetrical movement could provide different movement and loading through the pelvis and potentially encourage fetal movement or descent. However, these are biomechanical theories and have not been proven specifically with curb walking.
That doesn't mean curb walking is ineffective—it means we don't have enough evidence to tell you that it will start labor.
What About Regular Walking?
This is where we have more research.
Several studies have examined walking and physical activity during late pregnancy. Results have been mixed, but some randomized trials have found potential benefits.
One randomized clinical trial involving low-risk pregnant women found that 30 minutes of walking three times per week beginning at 38 weeks was associated with a lower rate of labor induction. However, the researchers did not find a difference in the gestational age at which spontaneous labor began.
Another randomized trial had pregnant women walk for 40 minutes four times per week beginning at 34 weeks. The walking group had higher Bishop scores, a measure of cervical readiness, and differences in spontaneous versus induced labor and delivery outcomes.
However, not every study has found a benefit. Research examining walking during labor has also produced mixed results, with some studies finding no meaningful difference in labor duration or delivery outcomes.
So while there is some evidence supporting regular physical activity and walking during pregnancy, we cannot take those findings and say that curb walking will induce labor.
Can Curb Walking Help Position the Baby?
This is another common claim you'll hear.
The theory is that the asymmetrical movement created by curb walking may give the baby opportunities to move or descend differently within the pelvis. From a biomechanical standpoint, this is a reasonable theory.
But again, we don't have strong research demonstrating that curb walking changes fetal position.
This is an important distinction because pregnancy and birth advice online can easily turn a plausible theory into a statement of fact.
Rather than saying, “Curb walking will turn your baby,” it is more accurate to say that curb walking creates movement variability and asymmetrical movement through the hips and pelvis, which may be one way to explore movement during late pregnancy.
So, Is Curb Walking Worth the Hype?
When patients ask me about curb walking, my answer is usually: don't think of it as a magic labor-induction technique. Instead, think of it as one possible way to keep moving and explore different positions during the final weeks of pregnancy.
For many pregnant individuals, movement throughout pregnancy can be beneficial, including during those final days and weeks. You don't need to stop moving simply because your due date is approaching.
If curb walking feels comfortable, it may be something you choose to incorporate into your day. But if you're doing it solely because you believe it will guarantee that labor starts, the research doesn't support that expectation.
And if curb walking doesn't feel good? You don't need to force it. There are plenty of other ways to move, change positions, and prepare your body for labor.
The Bottom Line
Curb walking has a plausible biomechanical rationale, but there isn't currently evidence showing that it directly induces labor.
Regular walking and physical activity during pregnancy have been studied more extensively, with some research suggesting potential benefits near term. But we should be careful not to confuse research on general walking with research on curb walking specifically.
At Jacobson Physical Therapy, we believe pregnancy education should be evidence-informed without being fear-based or overly restrictive. Our goal is to help you understand how your body is changing, stay active safely, and feel confident preparing for labor.
If you're pregnant and want individualized guidance on exercise, pelvic floor health, mobility, or labor preparation, Jacobson Physical Therapy provides mobile physical therapy throughout the Alpharetta, Milton, and Cumming areas.
