Study summary

This study is a non-blinded randomized controlled trial. Consenting participants will be randomized to routine post-operative ambulation vs. goal-augmented post-operative care (they will be given a goal number of steps to take on each post-operative day) following in-patient gynecologic surgery.

Read the detailed description

This study is a non-blinded randomized controlled trial. Consenting participants will be randomized to routine post-operative ambulation vs. treadmill-augmented post-operative care (placement of non-motorized treadmill in their room) following in-patient gynecologic surgery.

We will approach all women undergoing gynecologic procedures that are expected to ambulate within 12 hours of their operation and are anticipated to remain hospitalized at least 18 hours. Following confirmation of eligibility, we will enroll subjects either in the clinic when they are being consented for their gynecologic procedure or upon presentation to the hospital the day of their procedure. Randomization will occur at the completion of the gynecologic procedure when it has been confirmed by the primary surgeon that the patient is able to ambulate independently within 12 hours after completion of the procedure. At that time, participants will be randomized using opaque envelopes prepared by the study statistician in a 1:1 ratio to receive usual post-operative care or treadmill-augmented care.

All patients will have a pedometer placed on their person in the post-anesthesia recovery unit (PACU) which will be removed the day of their discharge. The primary outcome assessed will be number of steps taken in the 24 hour period prior to discharge as assessed by the electronic pedometer readings.

Pedometer will be placed on patients using a lanyard and pedometer clip in the recovery room. No participant will start ambulation without physician's clinical order. When the patient is ready for the first ambulation she will be accompanied by a nurse to sit up in a chair. Once the patient is able to ambulate herself she may ambulate in her room or in the hallway or if randomized to treadmill group she will be able to ambulate on the treadmill. She will be wearing her pedometer at all times until discharge from Loyola.

What researchers measure

Primary outcomes

  1. Number of Steps Taken in 24 Hours.

    The primary outcome assessed was the number of steps taken in the 24 hour period prior to discharge as assessed by the electronic pedometer readings.

    Time frame: 1 day

Results

Posted Jul 8, 2015
Limitations and caveats
Difficulty ensuring that encouragement was given, as we did not quantify the frequency of encouragement by the health care team. Loss of data due to loss of pedometers

Participant flow

This randomized controlled trial enrolled patients who were going to undergo gynecologic surgery were enrolled from 1/11-6/11 at Loyola University Medical Center .We approached adult (\>18 years) English speaking women prior to undergoing major gynecologic surgery who were expected to have at least a 24-hour hospital stay post-operatively.

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Oct 2010, a primary completion of Jun 2011 and a completion of Jun 2011. It does not say whether these dates are actual or estimated.

Results were first posted in Jul 2015, 4 years 1 month after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 8, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
