Swift Urgent Clinic is supported by Spine Nevada specialists in physical medicine, physical therapy, neurosurgery and radiology.
In order to diagnosis your condition, the providers at
Swift Urgent Clinic will gather patient history information and perform
a physical exam. Your provider may also order electrodiagnostic
tests to record and analyze electrical impulses between muscles
These electrodiagnostic tests (EDX) are used to diagnose, evaluate
and treat neuromuscular, musculoskeletal, and nervous system
disorders. There are two parts to the EDX test, nerve conduction
studies (NCS) and electromyography (EMG), usually performed
together during the same appointment.
It is the policy of the American Association of Neuromuscular &
Electrodiagnostic Medicine that EMG testing must be performed
by a trained physician. The physical medicine & rehabilitation
physicians (physiatrists) at SpineNevada are experienced in
Nerve conduction studies can show your physician how well
the body’s electrical signals are traveling to a nerve. During this test,
small electrical shocks are applied to the nerve in order to record
how the nerve works. The shocks may cause a quick, mild and
tingling feeling. The doctor may test several nerves.
During an EMG, a small, acupuncture size needle is placed
in several muscles to help diagnosis a back or neck condition.
There may be a bit of discomfort when the needle is inserted.
The physiatrist will only test the muscles necessary for diagnosis.
Physicians are able to see and hear the electrical signals that travel
from the needle to the EMG machine.
Common symptoms tested during an NCS/EMG:
Nerve conduction studies and EMGs are types of tests that the spine
physician may use to diagnose the following symptoms and others.
• Painful sensations in the neck and back may be due to an
underlying nerve root irritation.
• Pain radiating or shooting down the arms or legs.
• Pain may become aggravated with certain movements,
such as bending forward or lifting the arms overhead.
• Muscular symptoms may include cramps, spasms,
frequent muscle twitches, muscle weakness or loss of
• Other symptoms include lack of coordination of the hands
or feet, deterioration in handwriting, balance problems
and loss of control of bladder or bowel function.
What to expect during an NCS/EMG:
The EMG / NCS testing is relatively simple. It can be performed in the
office and will take from 20 to 90 minutes. Patients can do normal
activities, like eating, driving, and exercising, before and after the
You will be asked to step into an examination room, and to
change into an examination gown, unless you are wearing very
loose clothing that allows for easy access to your neck and arms and/
or your low back and legs. The test is usually performed with the
patient resting in a reclining position on a comfortable examination
table so that the muscles being tested are relaxed.
