Recent studies have described sensory-motor function alterations resulting from vibrations applied to various parts of the body. The present work describes the effects produced at the myotatic loop level by long-term vibration. Hoffmann and Tendon reflexes as well as tendon vibration response were substantially depressed by 18 Hz, +/- 0.25 G vibration applied to the whole body or to the legs of seated human subjects. The reflex inhibition lasted throughout the 15-min vibration period and persisted minutes after stimulus cessation. In contrast, vibration limited to the S's head and trunk showed much weaker effects. This suggests that the vibration acts mainly upon extero- and proprioceptive receptors rather than upon the vestibular organs. The results are discussed in relation to findings derived from experiments involving locally applied short-duration vibration.
近期研究描述了因身体各部位受到振动而导致的感觉运动功能改变。本研究描述了长期振动在肌伸张反射环水平产生的影响。对全身或坐着的人体受试者腿部施加18赫兹、±0.25克的振动,会使霍夫曼反射和腱反射以及腱振动反应显著减弱。反射抑制在整个15分钟的振动期间持续存在,并且在刺激停止后还会持续几分钟。相比之下,仅限于受试者头部和躯干的振动显示出的影响要弱得多。这表明振动主要作用于外感受和本体感受感受器,而非前庭器官。结合涉及局部应用短时间振动的实验结果对这些结果进行了讨论。
