[009] Citation: B. Hannaford, G. Cheron, L. Stark, 'The Effects of Applied Vibration on the Tri-Phasic EMG Pattern in Neurologically Ballistic Head Movements,'
Experimental Neurology, vol. 88, pp. 447-460, 1985.
Abstract
Vibration of agonist or antagonist muscle tendon produced changes in the
triphasic electromyographic pattern of neck muscles; EMG signals were rectified,
averaged, and also integrated by planimetry. The triphasic EMG envelopes
obtained during fast horizontal head rotation showed unmodified early agonist
pulse, the action pulse (PA), under all conditions; increased antagonist pulse,
the braking pulse (PB), only with antagonist muscle vibration; and increase of
late agonist pulse, the clamping pulse (PC), only with agonist muscle vibration.
Vibration experiments can be considered as a model for studying interactions
between central and peripheral effects on control of normal movements.
