This study investigated the effects of music listening on the anxiety, heart rate variability (HRV), and joint range of motion (ROM) of patients undergoing continuous passive motion (CPM) after total knee replacement surgery.
An experimental design was used. Participants in the experimental group (n = 49) listened to music from 10 min before receiving CPM until the end of the session (25 min in total) on the first and second day following surgery, whereas participants in the control group (n = 42) did not listen to music but rested quietly in bed starting 10 min before and throughout CPM.
Compared with the control group, the experimental group exhibited significantly lower anxiety levels (p < .05) and increased CPM angles (p < .05) during treatment and increased active flexion ROM (p < .05) upon discharge. The low-frequency (LF)/high-frequency (HF) power ratio, normalized LF HRV, and normalized HF HRV of the two groups differed significantly, indicating that the patients in the experimental group had greater parasympathetic activity compared with those in the control group.
Music listening can effectively reduce patient anxiety and enhance the ROM of their joints during postoperative rehabilitation. Health-care practitioners should consider including music listening as a routine practice for postoperative rehabilitation following orthopedic surgery.
本研究调查了听音乐对全膝关节置换术后接受持续被动运动（CPM）患者的焦虑、心率变异性（HRV）和关节活动范围（ROM）的影响。
采用实验设计。实验组（n = 49）的参与者在术后第一天和第二天接受CPM前10分钟开始听音乐，直至疗程结束（共25分钟），而对照组（n = 42）的参与者不听音乐，而是在CPM前10分钟开始并在整个CPM过程中安静地躺在床上休息。
与对照组相比，实验组在治疗期间焦虑水平显著降低（p < .05），CPM角度增加（p < .05），出院时主动屈曲ROM增加（p < .05）。两组的低频（LF）/高频（HF）功率比、归一化LF HRV和归一化HF HRV有显著差异，表明实验组患者的副交感神经活动比对照组更强。
听音乐可有效减轻患者焦虑，并在术后康复期间增加其关节活动度。医护人员应考虑将听音乐作为骨科手术后术后康复的常规做法。
