Ambulation for Latency During Expectant Management of PPROM

Purpose

Ambulation in pregnancy has been proposed to decrease stress and anxiety, increasing preterm birth. Whether ambulation is causally related to latency is unknown. The FitBit will be used for tracking the number of steps taken daily by each participant, and for encouraging the intervention group to walk. The FitBit is the most widely used physical activity tracker in medical research, and its use has been validated for research use in pregnant women. The purpose of the study is to evaluate whether ambulation in patients with preterm premature rupture of the membranes (PPROM) prolongs latency.

Conditions

  • Preterm Premature Rupture of the Membranes
  • Pregnancy Complications
  • Pregnancy, High Risk

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Ambulation Group
Participants in the ambulation arm will be allowed ad lib activity and instructed that they should walk at least once per day out of their room with a goal of 2,000 steps per day. The Fitbit InspireTM devices will be set to this goal and notifications will be given on the device for the participants meeting their goals. Upon enrollment, they will be given a pamphlet with instructions to ambulate out of the room at least once per day with a goal of 2,000 steps daily and their Fitbits will be pre-programmed with this goal. Study staff will also remind participants to ambulate via email, text or in-person if they are not meeting their goal of 2,000 steps per day.
  • Behavioral: Ambulation Group
    Participants in the ambulation arm will be allowed ad lib activity and instructed that they should walk at least once per day out of their room with a goal of 2,000 steps per day. The Fitbit Inspire devices will be set to this goal and notifications will be given on the device for the participants meeting their goals
Active Comparator
Routine Care
Participants in the routine care arm will be allowed ad lib activity but no encouragement to walk will be given. They will not have any goals set on their Fitbits. Upon enrollment, they will be given pamphlets with no instruction on whether or not to ambulate and their Fitbits will be pre-programmed to have no goal.
  • Behavioral: Routine Care
    No encouragement to ambulate will be provided to subjects. Their movement will be recorded
