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.
