1. The H reflex in normal, spastic, and rigid subjects. Archives of Neurology, excitability of the interneurone pathway. Any monosynaptic component will depend on the same factors as the ATR. In normal subjects with the ankle at 900 vibration of the type used in this study activates about 4000 of the motoneurone pool. The H vibration/H control ratio provides an estimate of the possible potency of presynaptic inhibition. In normal subjects, using the technique described in this study, blocking of about 6000 of the traffic in the monosynaptic line is possible;Angel, R.W.; Hofmann, W.W.,1963
