One of the most important factors affecting the sensory-motor integration is the myotatic reflex, which is done by muscle spindles (15).
Another explanation for the differences in neuromuscular preactivation between the mentioned muscles reflects that muscle tuning (Nigg, 2010) as a postural control strategy is adopted during WBV rather than myotatic reflex contractions.
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.
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.
Reticulospinal impulses alter muscle spindle sensitivity, thus modulating myotatic reflex sensitivity, but the rhythm for shivering probably reflects the generation within a spinal cord neural network of a rhythmical neural signal whose amplitude is controlled by the intensity of tonic reticulospinal signal.
They sense how far and fast a muscle is being stretched and, when activated, produce the myotatic stretch reflex.
Functionally, this loop provides a classic myotatic reflex: it damps small displacements of the joint by externally imposed force, and it may also damp SR reflex loops.
Objective: to investigate variations in the masseteric myotatic reflex (jaw-jerk) and the silent period from the 5th to the 9th decades of life.
In our present investigation, myotatic patella tendon reflex was recorded before and after the intervention to investigate the effect of WBV on the stretch reflex.
