(EMG) and Nerve Conduction Studies
An electromyogram (EMG) measures
the electrical impulses of muscles at rest and during contraction. Nerve
conduction studies, which measure nerve conduction velocity, determine
how well individual nerves can transmit electrical signals. Nerves control
the muscles in the body using electrical impulses, and these impulses make
the muscles react in specific ways. Nerve and muscle disorders cause the
muscles to react in abnormal ways.
An electromyogram (EMG) is done to:
Nerve conduction studies are done to:
Diagnose conditions that damage muscle
tissue, nerves, or the junctions between nerve and muscle (neuromuscular
junctions), for example, a herniated disc.
Evaluate the cause of weakness, paralysis,
involuntary muscle twitching, or other symptoms. Problems in a muscle,
the nerves supplying a muscle, the spinal cord, or the area of the brain
that controls a muscle can all cause these kinds of symptoms.
Detect and evaluate damage to the peripheral
nervous system, which includes all the nerves that lead away from the brain
and spinal cord and the smaller nerves that branch out from those nerves.
Nerve conduction studies are often used to help diagnose nerve disorders,
such as carpal tunnel syndrome.
Identify the location of abnormal sensations,
such as numbness, tingling, or pain
EMG /NCV testing should be considered
EMG /NCV testing is proudly offered
at our Pleasant Valley office.
There is no response to care, but symptoms
Subjective complaints are evident, but
objective findings are not supportive.
X-rays, CT, MRI, or EMG are negative,
yet symptoms persist.
There is non-resolving radicular pain.
A determination of nerve irritation
or damage needs to be made.
The need for further care is to be evaluated
Real vs. imagined pain is questioned.
