Electromyography (EMG) measures the electrical activity of muscles through intramuscular or surface electrodes. EMG signals can help characterize neurological and muscular diseases. Neuropathies produce longer, higher amplitude muscle action potentials with increased polyphasicity. Myopathies decrease action potential duration and area-to-amplitude ratio. EMG biofeedback uses electrode feedback to control muscle activation and is used to assess muscle imbalance.
Electrodiagnosis uses electrical technology to study the nervous system. It can provide information about nerve injuries, muscle injuries, muscle diseases, and prognosis. Electrical signals are generated in the brain and travel through the nervous system to muscles, causing contraction. Electromyography involves placing a needle in muscles to record electrical activity at rest, during minimal and maximal contraction. It can detect nerve injuries and other neurologic conditions. Nerve conduction studies involve electrically stimulating nerves to induce muscle responses like the H-wave, M-wave, and F-wave, which are analyzed to evaluate neurologic function. The H-wave specifically indicates input from muscle spindles to motor neurons and is used to diagnose peripheral neuropathies and other central
Electromyography (EMG) involves detecting and recording electrical potentials from skeletal muscles. EMG can be used to evaluate neuromuscular diseases or trauma. There are different types of electrodes used in EMG including surface electrodes, fine wire electrodes, and needle electrodes. During a clinical EMG, insertional activity is observed when the needle is inserted and electrical activity at rest and during voluntary contraction is examined.

Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.
10 Benefits an EPCR Software should Bring to EMS Organizations Traumasoft LLC
The benefits of an ePCR solution should extend to the whole EMS organization, not just certain groups of people or certain departments. It should provide more than just a form for entering and a database for storing information. It should also include a workflow of how information is communicated, used and stored across the entire organization.

5. Signal Competition: (gate control theory)
Relaxation: (muscle – referred pain inhibition)
Hormonal Response: (neuropeptide release)
Ionic Movement: (enzyme / substrate orientation)
Membrane Response: (sustained depolarization)
Noise Effect: (signal scramble, no re-excitation)
Self-Organizing Effect: (post-hyperactivity inhibition)
Quantum Effect: (vector potential – polarization effect)
Mechanism Description
Electric Signaling Effects
6. Signal Competition (gate control theory)
Large diameter afferent nerve fibers carry signals faster than the small unmyelinated
pain fibers, creating activity in the inhibitory circuits at the dorsal horn “gate”. This
blocks the perception of pain. (Melzack and Wall)
Mechanism Description
Electric Signaling Effects
7. Relaxation / Anti-Spasmodic Effects
Muscle Function :
Relaxation and spasm release decreases referred pain.
Neuron Function - Exhaustion:
Higher-rate electrical signals producing repeated action impulse at a rate which
cannot be effectively followed by the human nervous system. This depletes the
synaptic transmitters necessary for continued action potential propagation.
Mechanism Description
Electric Signaling Effects
8. Hormonal Response: (neuropeptides)
Increase in Dopamine Concentration:
Electric Signaling (with specific parameters) significantly increases dopamine
concentration (pain inhibitory transmitter)
Decrease in Norepinephrine, Serotonin:
Electric signaling (with specific parameters) decreases norepinephrine and serotonin
(excitatory transmitters).
Mechanism Description
Electric Signaling Effects
9. Hormone Response
Endogenous Opiate Release:
Electric signaling induces the release of powerful endogenous opiates, like
enkephalins and endorphins (morphine effect)
ACTH Secretion:
Electric signaling induces ACTH secretion (MSH hormone). ACTH secretion-induced
melanin becomes insulators when electric cell signals exceed the sensory or motor
threshold (signal inhibition).
Mechanism Description
Electric Signaling Effects
10. Ion Movement
Pain Mediator (metabolite) Response:
Under the influence of alternating–polarity electric fields, ion movement balances
metabolite concentration differences (pH).
Metabolic Facilitation:
A direct Influence on enzyme/substrate activity, which increases the probability of
hormone/ligand “favorable” orientation, transition state and the breakdown of pain
producing metabolites.
Mechanism Description
Electric Signaling Effects
11. Cell Membrane Response
Sustained Membrane Depolarization:
Multiple electric signals, which fall within the refractory period of the cell membrane
induce sustained depolarization…inhibiting the transport of pain signals along the
nerve axon.
Second Messenger Formation (cAMP):
An influence on voltage-gated channels, initiating second messenger formation
(cAMP). This directs all “cell-specific” activity…activates regenerative processes and
the repair of the cell membrane.
Mechanism Description
Electric Signaling Effects
12. Noise Effect
Scrambling Out the Perception of Pain:
Electric stimulation produces noise signals that excite a large area of nerves, self-
focused nerve conduction cannot stabilize…the signal is diffused…no lateral
occurs, re-excitation is impossible.
Disturbance of the Self-Organizing Structure:
Chaotic self-organizing is a decisional factor of signal transmission in living systems
(neuronal pool)...spatio-temporal order is chaotically rearranged…neuronal pool
transmission is altered or inhibited.
Mechanism Description
Electric Signaling Effects
13. Quantum Effects
Cell Membrane Processes:
All microscopic events (cell membrane processes, biochemical events, etc. are
determined by quantum-mechanical rules… electromagnetic potentials determine
processes, not the field
Vector Potential:
Change in vector potential effectively alters the quantum bio-processes…all of the
micro-reactions are dynamical. Vector potential determines water polarization states
(sodium channel).
Mechanism Description
Electric Signaling Effects
14. Stimulatory Class
The physiological effects induced by repeated action potentials in cells
(depolarization and subsequent repolarization activitexcitabley).
Multi-Facilitation Class
The physiological effects induced without action potentials (NO
depolarization and repolarization activity). These include biochemical
effects.
