Abstract：
OBJECTIVE: To assess postural stability, specifically center of body sway during single-leg standing balance, among individuals with and without forward head posture (FHP) during smartphone use.
METHODS: The research recruited 53 healthy smartphone users, aged 18-25, and categorized them into FHP group comprising 26 subjects and the normal (control) group with 27 subjects. Participants were assigned the task of maintaining balance while engaged in smartphone typing during single-leg standing. The experiment involved four specific conditions according to neck posture and stable of surface. The study meticulously quantified body center of pressure (COP) sway amplitudes using the Nintendo Wii Balance Board.
RESULTS: The research revealed that individuals with FHP exhibited significantly greater body sway compared to the control group when using smartphones. Notably, distinct variations were observed in path length sway, anteroposterior (AP), and mediolateral (ML) sway amplitude, particularly evident when maintaining flexed neck positions on a soft surface while engaged with smartphones.
CONCLUSIONS: These findings strongly suggest that individuals with FHP encounter deteriorated postural stability during smartphone use, particularly in challenging head positions.

摘要：
■为了评估姿势稳定性，特别是单腿站立平衡时身体摇摆的中心，在使用智能手机期间有和没有前头姿势(FHP)的个体中。
■这项研究招募了53名健康的智能手机用户，年龄在18-25岁之间，并将其分为由26名受试者组成的FHP组和由27名受试者组成的正常（对照）组。参与者被分配了在单腿站立期间进行智能手机打字时保持平衡的任务。根据颈部姿势和表面稳定性，实验涉及四个特定条件。该研究使用任天堂Wii平衡板精心量化了身体压力中心（COP）摇摆幅度。
■研究表明，与使用智能手机的对照组相比，患有FHP的个体表现出明显更大的身体摇摆。值得注意的是,在路径长度摇摆中观察到明显的变化，前后（AP），和中外侧(ML)摇摆幅度，当与智能手机接合时，在柔软的表面上保持弯曲的颈部位置尤其明显。
这些发现强烈表明，FHP患者在智能手机使用过程中姿势稳定性下降，特别是在具有挑战性的头部位置。
