About this study

Official title: Aerobic, Strength, Kegel (ASK) Exercise Intervention Perceptions for Postpartum Health: a Pilot Randomized Controlled Trial

The goal of this pilot clinical trial is to learn whether a 12-week home-based exercise programme is feasible, acceptable, and safe for postpartum women in Hong Kong who had hypertensive disorders of pregnancy. The exercise programme is called the Aerobic, Strength, and Kegel exercise programme, or ASK programme.

The main questions this study aims to answer are:

Read more
  • Can postpartum women follow the ASK exercise programme at home?
  • Is the ASK exercise programme acceptable and safe?
  • Does the ASK exercise programme show early benefits for postpartum recovery and health?

Researchers will compare women who receive the ASK exercise programme with women who receive standard postnatal care.

Participants will be randomly assigned to one of the two groups. They will complete study assessments at the beginning of the study and after 12 weeks. Women in the ASK exercise programme group will complete three 60-minute exercise sessions per week for 12 weeks, supported by a mobile app and wearable device. Women in the standard postnatal care group will continue to receive usual postnatal care.

Read the detailed description

This is a parallel-group pilot randomized controlled trial designed to evaluate the feasibility, acceptability, safety, and preliminary effectiveness of the ASK Programme, a 12-week home-based postpartum exercise intervention for Asian women in Hong Kong. The ASK Programme combines aerobic training, strength training, and Kegel-based pelvic floor muscle training, and is delivered through a study app with wearable-supported monitoring.

Eligible participants will be enrolled at 6 to 8 weeks postpartum and randomized in a 1:1 ratio to either the ASK Programme intervention group or the standard postnatal care control group. Participants in the intervention group will complete three home-based ASK exercise sessions per week for 12 weeks. Each session will include warm-up, aerobic training, strength training, pelvic floor muscle training, and cool-down. The control group will receive standard postnatal care.

Assessments will be conducted at baseline and within 1 week after completion of the 12-week intervention. The study will collect feasibility, adherence, safety, acceptability, clinical, behavioral, psychosocial, physiological, cardiometabolic, and exploratory biological data to inform the design of a future full-scale randomized controlled trial.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recruitment rate to the ASK Exercise Programme

    Recruitment rate will be calculated as the number of participants enrolled divided by the number of eligible participants approached. The outcome will be reported as a percentage of eligible participants approached.

    Measured: From recruitment initiation to 12 weeks

  2. Retention rate in the ASK Exercise Programme

    Retention rate will be calculated as the number of enrolled participants who complete the 12-week follow-up assessment divided by the total number of enrolled participants. The outcome will be reported as a percentage of enrolled participants.

    Measured: From baseline to 12 weeks

  3. Dropout rate from the ASK Exercise Programme

    Dropout rate will be calculated as the number of participants who withdraw or are lost to follow-up before the 12-week assessment divided by the total number of enrolled participants. The outcome will be reported as a percentage of enrolled participants.

    Measured: From baseline to 12 weeks

  4. Assessment completion in the ASK Exercise Programme

    Assessment completion rate will be calculated as the number of completed planned study assessments divided by the total number of planned study assessments. The outcome will be reported as a percentage of planned study assessments.

    Measured: From baseline to 12 weeks

  5. Participant satisfaction rate

    Participant satisfaction will be assessed using a study-specific acceptability questionnaire administered at 12 weeks. Satisfaction will be defined as reporting "satisfied" or "very satisfied" with the ASK Exercise Programme. The outcome will be reported as the percentage of participants who are satisfied or very satisfied.

    Measured: At 12 weeks

  6. ASK session completion rate

    ASK session completion rate will be calculated as the number of prescribed ASK exercise sessions completed divided by the total number of prescribed ASK exercise sessions during the 12-week intervention period. Session completion will be assessed using app-recorded exercise completion data. The outcome will be reported as a percentage of prescribed ASK exercise sessions.

    Measured: Throughout the 12-week intervention period

  7. Adverse events related to the ASK Exercise Programme

    Safety will be assessed as the number of participants who experience one or more adverse events related to the ASK Exercise Programme during the 12-week intervention period. Adverse events and exercise-related symptoms will be collected using participant symptom reports and study adverse event records. The outcome will be reported as the number of participants with adverse events related to the ASK Exercise Programme.

    Measured: Throughout the 12-week intervention period

  8. Postpartum recovery score

    Postpartum recovery will be assessed using the Obstetric Quality of Recovery-10. The change from baseline to 12 weeks in the total Obstetric Quality of Recovery-10 score will be calculated. Total scores range from 0 to 100, with higher scores indicating better postpartum recovery.

    Measured: Baseline and 12 weeks

  9. Postnatal depressive symptom score

    Postnatal depressive symptoms will be assessed using the Edinburgh Postnatal Depression Scale. The change from baseline to 12 weeks in the total Edinburgh Postnatal Depression Scale score will be calculated.
