Summary
A walking prescription helps liver transplant candidates prepare for surgery. We recommend daily step goals based on 6-minute walk test distances, aiding healthcare professionals in prescribing appropriate physical activity.
Area of Science:
- Transplant Medicine
- Exercise Physiology
- Physical Therapy
Background:
- Pre-transplant physical conditioning is crucial for liver transplant recipients.
- Standardized guidelines for prescribing walking exercise are lacking.
Purpose of the Study:
- To correlate 6-minute walk test (6MWT) distances with daily step counts.
- To establish evidence-based walking prescriptions for liver transplant candidates.
Main Methods:
- Patients undergoing 6MWT completed the test.
- Average daily steps were recorded using personal fitness trackers.
- 6MWT results were correlated with daily step data.
Main Results:
- A 6MWT distance <250 m correlated with a recommendation of 1500 steps/day.
- A 6MWT distance of 250-349 m correlated with 3000 steps/day.
- A 6MWT distance ≥350 m correlated with 6000 steps/day.
Conclusions:
- This study provides practical, step-based recommendations for pre-liver transplant exercise.
- Healthcare professionals can use these findings to tailor walking prescriptions.
- Personal fitness trackers can effectively monitor daily activity for transplant candidates.
