Diaphragmatic Breathing Exercises for Total Knee Arthroplasty Patients

This observational study is looking at whether simple diaphragmatic breathing exercises can help manage pain and anxiety, and reduce the need for opioid pain medication, after total knee replacement surgery. Researchers will compare pain levels, anxiety levels, and opioid use in patients who learn and perform these breathing exercises to a group of past patients who did not. You may be able to join if you are between 50 and 90 years old, are having a total knee replacement, and will have a continuous peripheral nerve block catheter (a type of pain relief). This study is currently unclear on its recruitment status and aims to enroll 50 participants.

Study design
This is an observational study comparing 50 participants who learn diaphragmatic breathing to a control group of past patients. It is not a randomized controlled trial.
What's involved
You will be taught how to perform diaphragmatic breathing exercises using a handout and videos before and after surgery. Your pain and opioid use will be measured.
Compensation
Not stated in the trial record.
Follow-up
Pain, opioid usage, and anxiety levels are measured prior to intervention, but the duration of follow-up after intervention is not specified.
