Knee replacement trial finds lower postoperative pain scores with noise control or music
Pain findings favored all intervention groups; anxiety findings favored passive noise control and chosen music.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
During knee replacement surgery, noise control devices and patient-selected music were followed by lower postoperative pain scores than the control condition. Passive noise control and music also showed greater reductions in situational anxiety. The abstract supports a possible short-term benefit in this surgical setting, but does not show how large the improvements were.
The abstract gives no pain or anxiety effect sizes and does not identify who was blinded. This abstract-based summary cannot establish the size of benefit or fully assess possible influences on subjective ratings.
What researchers found
Visual Analog Scale pain scores: significance statistic
Each intervention group had lower scores than control at 24 h. This P value indicates that such results would be unlikely if there were no real group difference; it does not quantify pain reduction.
Anxiety results need separation
The situational anxiety measure showed greater reductions for passive noise control and music than for control. The abstract does not establish whether active noise control improved anxiety or whether any intervention outperformed another.
What vital signs showed
During surgery, pulse, blood pressure, breathing rate and temperature differed across groups. Some postoperative pulse and temperature differences were also reported, but the abstract gives neither their direction nor their size.
