Can a simple step test replace the 6-Minute walk for heart rehab?
NCT ID NCT04699136
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether a 6-minute stepper test (ST6) can accurately measure exercise tolerance in people with heart conditions undergoing rehabilitation. Researchers compared the stepper test results with the standard 6-minute walk test and a cardiac stress test in 60 patients. The goal was to see if the stepper test is a valid, practical alternative for assessing heart patients' fitness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could provide a simpler, space-saving way to assess exercise capacity in heart patients during rehabilitation.
- What could go wrong
- This is a small, completed validation study, not a treatment trial. The stepper test may not prove as reliable as existing methods for all patients.
