A slow angular velocity (5 [degrees].[s.sup.-1]) was set in order to avoid the myotatic reflex (Kay and Blazevich 2010) to obtain a good resolution of the fascicles via ultrasonography.
Of clinical significance for motor activity are myotatic reflex, inverse myotatic reflex and gamma loop reflex, which provide appropriate muscular speed and efficacy [2].
However, there are few studies that assess the myotatic reflex electrical signal of muscles when stretched (5,34).
One of the most important factors affecting the sensory-motor integration is the myotatic reflex, which is done by muscle spindles (15).
(1-13) The reflexive myotatic response of suboccipital muscles has been proposed by several authors as a likely mechanism to place the dura under tension.
The present study monitored the time course of the effects of this molecule on classical electrophysiological parameters of the myotatic reflex arc (H reflex and M response).
Initially manual straightening of the limbs was attempted for application of plaster cast to introduce the inverse myotatic reflex with relaxation of the flexor muscles.
In the myotatic reflex, the transmitter is glutamate at the excitatory synapse between the la fibres and the motor neurons in the ventral horn of the spinal cord; these drugs reduced its quantal release by a presynaptic mechanism, leading to 'inhibition' through reduced efficacy of an excitatory synapse.
They sense how far and fast a muscle is being stretched and, when activated, produce the myotatic stretch reflex.
