The effects of different stimuli (including visual and auditory) on the tonic vibration reflex (TVR) and accompanying motor illusions were analyzed. The vibration of different limb muscles in the absence of vision caused reflex activation of their antagonists (inverted TVR) if no other stimulation or instruction was applied. An autogenic TVR was observed during auditory, vestibular stimulation, or subject's mental activity. Emergence of the autogenic TVR was attributed to 'distraction of subject's attention'. Vibration-induced illusions of movement in isometric conditions also changed their direction due to the experimental paradigm.
