Abstract

A recent study has shown that fatigue of the posterior neck muscles, induced by prolonged isometric contractions, causes self-motion misperception. The present study investigates whether focal vibration of the posterior neck muscles can prevent or abolish it. Self-motion perception was assessed by analyzing the tracking of a ground-fixed visual target during passive sinusoidal horizontal trunk rotation, both symmetric and asymmetric, with a stationary head. After prolonged isometric contractions that induced posterior neck muscle fatigue, perceptual responses to symmetric sinusoidal trunk rotation showed a decrease in gain at lower rotation velocities, and an increase in the final position error (FPE). The changes in gain and FPE were completely prevented by prior high-frequency vibration (100 Hz for 3 min) of the posterior neck muscles, whereas they were eliminated when the vibration was applied after the fatigue-induced deficit had already occurred. We suggest that the focal vibration activating the neck muscle proprioception may inhibit fatigue signals, possibly through a gate control mechanism. Furthermore, the persistence of the vibratory effects was examined by testing the perceptual gain and the FPE after prolonged vibratory application (three separate sessions of ten minutes each, at 1 min rest intervals). It was found that the effects of fatigue on the FPE was eliminated even one week after vibration. This finding suggests that the focal vibratory procedure may be useful to attenuate the impact of fatigue on self-motion perception, potentially preventing deterioration of balance and orientation abilities.

长时间的颈部本体感觉振动刺激防止由颈部肌肉疲劳引起的自我运动错觉:即时和持续的效果。
最近的一项研究表明,由长时间等距收缩引起的后颈部肌肉疲劳会导致自我运动的误解。本研究探讨了后颈部肌肉的局部振动是否可以预防或消除它。通过分析头部静止时被动正弦水平躯干旋转(对称和非对称)对地面固定视觉目标的跟踪,评估了自运动感知。在长时间的等距收缩引起后颈部肌肉疲劳后,对对称正弦躯干旋转的感知反应显示,在较低的旋转速度下,增益减少,最终位置误差(FPE)增加。增益和FPE的变化完全被后颈部肌肉先前的高频振动(100 Hz 3分钟)所阻止,而当疲劳引起的缺陷已经发生后施加振动时,它们被消除了。我们认为,激活颈部肌肉本体感觉的局部振动可能通过门控机制抑制疲劳信号。此外,通过测试长时间振动应用后的知觉增益和FPE(每次10分钟,每隔1分钟休息)来检验振动效应的持久性。结果表明,疲劳对FPE的影响在振动一周后消失。这一发现表明,局部振动过程可能有助于减轻疲劳对自我运动感知的影响,潜在地防止平衡和定向能力的恶化。
