NCT ID NCT07075549
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at a questionnaire designed to measure how leg swelling (lymphedema) affects daily life. Researchers tested a French version for accuracy and checked if the Dutch version can track changes over time. Over 450 people with leg lymphedema filled out the questionnaire twice. The goal was to make sure the tool works well for French and Dutch speakers.
