Official title: The Effect of Routine Activity on the Risk for Preterm Delivery in Women With a Short Cervix. A Randomized Control Trial
Run by Wolfson Medical Center · NCT06884761 · Data updated 2026-11-12
This study is testing if staying active instead of resting a lot can help pregnant women with a short cervix avoid having their babies too early.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are pregnant women with singleton pregnancies between 24 and 34 weeks who have a cervical length of less than 25 mm.
✕Probably not a fit
Patients with twin pregnancies, medical contraindications to physical activity, or other serious maternal or fetal complications may not benefit from this study.

What this trial studies
This clinical trial evaluates the effects of routine physical activity compared to strict bed rest on the risk of preterm delivery in pregnant women diagnosed with a short cervix between 24 and 34 weeks of gestation. Participants will be randomized into two groups: one group will maintain their usual activity levels while the other will be advised to rest maximally. The study aims to determine if routine activity influences gestational age at delivery and secondary outcomes such as preterm labor and maternal anxiety. Participants will wear a smart band to monitor their activity levels over a two-week period and will have regular follow-ups at a high-risk pregnancy clinic.
Why it matters
Potential benefit: If successful, this study could provide evidence that routine activity may reduce the risk of preterm delivery in women with a short cervix.
How similar studies have gone: While there have been studies on activity levels during pregnancy, this specific approach focusing on women with a short cervix is relatively novel.
