Proprioceptive afferent input from neck muscles plays an important role in postural control. Forward head posture has the potential to impair proprioceptive information from neck muscles and contribute to postural control deficits in patients with neck pain. This study investigated whether induced forward head posture affects postural control in healthy participants when compared to natural head posture. Centre of pressure sway area, distance covered and mean velocity were measured during 30s of static standing using a force platform with 25 healthy individuals (mean age ± SD = 20.76 ± 2.19 years) in 8 different conditions. Base of support, eyes open or closed and natural or forward head posture varied within these testing conditions. The majority of comparisons between natural and forward head posture were not statistically significant (p>0.05). This suggests that induced forward head posture in young healthy adults does not challenge them enough to impair postural control. Future studies should evaluate whether forward head posture affects postural control of individuals with chronic neck pain.
颈部肌肉的本体感觉传入在姿势控制中起着重要作用。头部前倾的姿势有可能损害颈部肌肉的本体感觉信息，并导致颈部疼痛患者的姿势控制缺陷。本研究旨在比较自然头位和诱导的头部前倾位时，健康参与者的姿势控制是否会受到影响。使用测力板，对 25 名健康个体（平均年龄 ± 标准差=20.76 ± 2.19 岁）在 8 种不同条件下进行 30 秒的静态站立测量，记录了中心压力摆动面积、覆盖距离和平均速度。在这些测试条件下，支撑基础、睁眼或闭眼以及自然或头部前倾位发生了变化。在自然头位和头部前倾位之间的大多数比较均无统计学意义（p＞0.05）。这表明，在年轻健康成年人中诱导的头部前倾位不足以对姿势控制产生影响。未来的研究应评估头部前倾位是否会影响慢性颈部疼痛患者的姿势控制。
