During a balanced bilateral vibration of tensor fasciae latae muscles evoking no evident postural changes in a standing human the slow head turns resulted in a pronounced lateral common gravity centre displacements to the 'occipital' side. Neck influences were most prominent at intermediate tonic background and were lacking both during very weak and strong vibratory stimulation in contrast to usual tonic vibratory reflex which becomes stronger with the increase of frequency. Body sway was induced not only by actual head turns but also by illusory ones evoked by neck muscle vibration. The neck influences on standing posture are therefore present in healthy adults, but they require a definite level of tonic readiness for their manifestation and are incorporated in the whole system of body scheme mechanisms.
在阔筋膜张肌进行双侧平衡振动时，站立的人体未出现明显的姿势变化，而缓慢的头部转动导致重心明显向“枕部”一侧横向位移。颈部影响在中等紧张背景下最为显著，与通常随频率增加而增强的紧张性振动反射不同，在非常微弱和强烈的振动刺激期间均不存在。身体摆动不仅由实际的头部转动引起，也由颈部肌肉振动诱发的虚幻转动引起。因此，颈部对站立姿势的影响在健康成年人中存在，但它们需要一定程度的紧张准备才能表现出来，并融入身体图式机制的整个系统中。
