Summary

This trial examines whether breathing exercises can reduce pain after total knee replacement surgery. Researchers enroll 55 adults over 18 who speak Turkish and have no communication or sensory barriers. Participants receive the breathing exercise intervention, and researchers measure pain intensity using a 0 to 10 numerical rating scale. The goal is to see if this non-drug method helps control postoperative pain and support recovery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
breathing exercises
What this could lead to
If breathing exercises help, they could offer a simple, drug-free way for nurses to ease pain after knee replacement surgery and support faster recovery.
What could go wrong
This is a small study of 55 people, and breathing exercises may not relieve pain enough on their own. Results may not apply to other surgeries or patients with different pain needs.
