Effects of music therapy on physiological outcomes for post-operative total knee arthroplasty (TKA) patients

Abstract

This study aimed to investigate the effects of music on physiological outcomes for post-operative TKA patients in the recovery unit. Fifty-six patients from Hospital Melaka were randomized equally into intervention (IG) and control groups (CG). IG received the usual care and listened to selected music for 60 min, while the CG received only the usual care. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiration rate (RR) and oxygen saturation (SpO₂) were measured on arrival and after 10, 20, 30, and 60 min in the recovery unit. A significant difference between groups was observed in RR upon arrival (U = 276.5, p = 0.029) and after 10 min (U = 291, p = 0.45). Meanwhile, there were significant differences in DBP (F = 3.158, p = 0.032), RR (χ² = 15.956, p = 0.003) and SpO₂ (χ² = 14.084, p = 0.007) over time in the IG. Overall, listening to music immediately after TKA has an effect on DBP, RR, and SpO₂.
