Abstract

One hundred seconds of vibration of the Achilles tendon at a frequency of fifty-three hertz suppressed both the Achilles tendon reflex (ATR) and the H-response in each of the fourteen normal subjects tested. After vibration stopped, the ATR was potentiated and the H-response returned but was depressed. Neural mechanisms are proposed to explain these interactions of the tonic and phasic stretch reflexes.
