NCT ID NCT07586436
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether using a stress ball or doing breathing exercises can reduce pain and keep vital signs stable when a surgical drain is removed after knee replacement. About 105 adults will be split into three groups: stress ball, breathing exercises, or standard care. The goal is to find simple, drug-free ways to make this short but painful procedure more comfortable.
