Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bed rest has been a commonly prescribed intervention for high risk pregnancies, despite the lack of data to support its benefits, and increasing evidence pointing to potential harms. In this study, the effects of bed rest compared to moderate activity will be on maternal mood and muscle strength will be evaluated in patients with preterm premature rupture of membranes (PPROM).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Historically, bed rest has been considered a beneficial treatment option for patients with high risk pregnancies. The definition of bed rest varies between providers, and can mean anything from being completely bed-bound for months at a time (sometimes called strict bed rest) to walking around within the home a few times a day (sometimes called modified bed rest). Recent studies have highlighted potential harmful effects from bed rest. However, scientific studies need to be carried out to compare the effects of bed rest and moderate activity on the health of mothers and babies.

PPROM is defined as rupture of membranes prior to 37 weeks gestation prior to the onset of labor, and affects approximately 3% of all pregnancies in the Unites States. Women with PPROM are routinely managed in the inpatient setting from the time of diagnosis until delivery. Therefore, PPROM patients are a closely supervised and easily accessible cohort of women.

In this study, participating patients with PPROM will be randomized into two groups: bedrest or moderate activity. Maternal mood and muscle strength will be assessed at enrollment and after delivery to determine whether there are significant differences in these outcomes in the two groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Bedrest

Bedrest is a standard recommendation for patients with PPROM. Subjects randomized to this arm of the study will undergo the following:

1. Receive recommendation for bedrest (standard of care).
2. Have maternal mood and muscle strength evaluated on enrollment and after delivery (observational study procedure).
3. Wear a pedometer to measure activity when out of bed (observational study procedure).

Group Type NO_INTERVENTION

No interventions assigned to this group

Moderate Activity

Subjects randomized to this arm of the study will undergo the following:

1. Receive recommendation to ambulate 150 feet, twice per day (interventional study procedure). Prior to each session of ambulation, an ultrasound will be performed to ensure adequate amniotic fluid volume and appropriate fetal position, and a fetal heart rate tracing will be obtained to ensure that there is reassuring fetal status (observational study procedure). During each session of ambulation, the fetal heart rate tracing will be monitored continuously (observational study procedure).
2. Have maternal mood and muscle strength evaluated on enrollment and after delivery (observational study procedure).
3. Wear a pedometer to measure activity when out of bed (observational study procedure).
