Just as cardiologists use an electrocardiogram (a test to measure the
electrical activity of the heart), spinal specialists use electrical
studies to determine the function of the nerves and muscles.
These tests can show both the patient and practitioner what progress
is being made with treatment.

Needle Electromyography
by Dr. Gary Farr 4/22/2002
An EMG is sometimes recommended to assess the electrical activity of a nerve root. After three weeks of pressure on a nerve root, the muscle the nerve goes to will begin to spontaneously contract.
Somatosensory Evoked Potentials (SSEP)
by Dr. Gary Farr 4/22/2002
SSEP’s are sometimes ordered to assess the speed of electrical conduction across the spinal cord. If the spinal cord is significantly pinched, the electrical signals will travel slower than usual.

Surface Electromyography
by Dr. Gary Farr 4/22/2002
The letters EMG represent Electro Myo Graphy, which refers to the measurement of electrical activity of muscles. In a similar way, ECG refers to Electro Cardio Graphy which is the measurement of electrical activity of the heart muscle. Just as cardiologists use ECG or EKG to accurately evaluate the heart, and neurologists use EEG to accurately evaluate the brain, chiropractors, neurologists, researchers and clinicians use surface EMG to more accurately evaluate muscles. EMG measures the capacity of muscles to function.
