Session presented on Saturday, July 23, 2016 and Sunday, July 24, 2016: EFFECTIVENESS OF MUSIC LISTENING ON PATIENTS WITH TOTAL KNEE REPLACEMENT DURING CPM REHABILITATION Pi-Chu Lin College of Nursing, Taipei Medical University, Taipei, Taiwan Abstract Content: Aims: This study investigated the effects of music listening on the anxiety, heart rate variability (HRV), and range of motion of joints in patients who were implementation of continuous passive motion (CPM). Methods: An experimental design was adopted, and the participants were patients who received total knee replacement (TKR) surgery (experimental group = 49 patients; control group = 42 patients). The experimental group began listening to music 10 min before receiving CPM at 10 AM until the end of CPM (25 min in total) on the first and second days after the surgery, whereas the control group was required to rest in bed. Results: (1) the experimental group exhibited significantly lower anxiety levels than the control group did (p < .05); (2) the experimental group had significantly higher increase in angles for each CPM implementation compared with the control group (p < .05), and the active flexion angles of the experimental group were higher than those of the control group (p < .05) at discharge; and (3) the low frequency/high frequency power (LH/HF) ratio, normalized low frequency (nLH), and normalized high frequency (nHF) HRV of the two groups differed statistically significantly, indicating that compared with the control group, the experimental group had superior parasympathetic nervous regulation. Conclusions: Music listening can effectively lower patient anxiety levels and enhances the range of motion of joints during postoperative rehabilitation. Therefore, this study suggested that music be included as one of the routine practices for postoperative rehabilitation of orthopedic surgeries.
