Mechanisms involved in referred pain, temporal summation, muscle hyperalgesia, and muscle pain at rest were attenuated by the N-methyl-D-aspartate (NMDA) antagonist, ketamine, in FM patients. Delayed ...

Temporal summation is produced by stimulating the muscle rapidly enough so that one contraction is not finished before another begins. Thus, the effect of the second contraction is added to at least a part of the first contraction, and so on.

Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the...

• If you wait until relaxation is complete from the first stimulus, then give a second stimulus to the same muscle, temporal summation will not occur.

This study applies a multi-modal test procedure11 to clarify three aspects of the pharmacological actions of epidural fentanyl: segmental spread, modulation of temporal summation and muscle pain.
