About this trial
Rationale: While total knee replacements (TKA) are one of the most commonly performed surgical procedures in the United States, this procedure can also be very painful. Postoperative mobilization and rehabilitation is vital to a patient's recovery, but inadequate pain control can impede patients' progress. Diaphragmatic breathing is an additional non-pharmacological and non-invasive tool with no adverse effects that could aid in recovery. This will serve as a pilot study for a possible larger controlled trials.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients (participants) undergoing total knee arthroplasty with a continuous peripheral nerve block catheter
Disqualifiers
Inability to perform or learn diaphragmatic breathing exercises or do not wish to participate in diaphragmatic breathing or study protocol
Pregnant patients
Patients without continuous peripheral nerve block catheter
Trial population
Patients (participants) undergoing total knee arthroplasty with placement of continuous peripheral nerve block catheter between the ages of 50-90 years of age at the Keck Hospital of USC who want to participate and consent to participate in the study. The control group will be made up of patients( 50-90 years of age) who underwent total knee arthroplasty with placement of a continuous peripheral nerve block catheter over the year prior, without participation in breathing exercises, at the Keck Hospital of USC.
