The effect of noise on the postural control process is of ongoing interest. This exploratory study aims to determine the effect of personal listening devices (PLD) on postural stability among adolescents and young adults.
Participants aged between 13 and 25 with a history of PLD usage were included. The study was carried out in two parts. The first part involved determining the PLD listening level and the preferred sound level. In the second part, postural stability was assessed using the modified Clinical Test for Sensory Interaction in Balance (mCTSIB) and dynamic postural stability.
64 participants were recruited with a mean age of 18.78 (SD: 3.11). The majority were female (62.5%) and of Chinese ethnicity (38.1%). The reported mean PLD listening level and preferred volume levels were 57.50 dB (SD: 6.15) and 46.48% (SD: 15.98), respectively. Male PLD users had higher listening levels and preferred volume levels. Adolescents were found to have a higher listening level than young adults. Female PLD users revealed a higher sway and postural stability index than male PLD users. Young adults were found to have a higher sway and postural stability index. Statistical significance is demonstrated between the age of PLD users and mCTSIB sway index (coef: 0.367; p = 0.003).
The current study suggests that the younger generation is susceptible to postural instability following PLD exposure. Yet, the provided data is inadequate to draw a conclusion, and future randomised controlled studies with large sample sizes are warranted.
噪声对姿势控制过程的影响一直是人们关注的焦点。本探索性研究旨在确定个人听力设备（PLD）对青少年和青年成年人姿势稳定性的影响。
纳入年龄在13至25岁之间且有PLD使用史的参与者。该研究分两部分进行。第一部分涉及确定PLD的收听水平和偏好音量水平。第二部分使用改良的平衡感觉交互临床测试（mCTSIB）和动态姿势稳定性来评估姿势稳定性。
招募了64名参与者，平均年龄为18.78岁（标准差：3.11）。大多数为女性（62.5%），华裔（38.1%）。报告的PLD平均收听水平和偏好音量水平分别为57.50分贝（标准差：6.15）和46.48%（标准差：15.98）。男性PLD使用者的收听水平和偏好音量水平更高。发现青少年的收听水平高于青年成年人。女性PLD使用者的摇摆和姿势稳定性指数高于男性PLD使用者。发现青年成年人的摇摆和姿势稳定性指数更高。PLD使用者年龄与mCTSIB摇摆指数之间存在统计学意义（系数：0.367；p = 0.003）。
当前研究表明，年轻一代在接触PLD后易出现姿势不稳定。然而，所提供的数据不足以得出结论，未来有必要进行大样本量的随机对照研究。
