When discussing needle size we can look at two characteristics: length and diameter.
The length of the needle used can vary based upon the examiner's preference or how much tissue exists between the skin and the desired muscle for the doctor to examine. Most needles are usually around one and one half inches but the sizes tend to vary from 1-3 inches in length
The diameter of the needle is measured in gauges, with the larger the number of the gauge corresponding to a smaller diameter. Most needles used for EMGs range from 26 gauge to 30 gauge.
Most of the pain that occurs with any needle insertion is usually from the initial insertion of the needle through the skin. This reduced by the technique of the doctor, the gauge (or diameter) of the needle, and the shape of the tip of the needle.

There are two types of test you should be getting; one is a nerve conduction study and the second is an EMG. An EMG is where the provider uses very small needles that are inserted into the muscles of the arms and sends small electrical impulses to test certain nerves in the upper extremities. No there is just about nothing too it. Had the test done on both hands and hardly remember having it done other then paying the doctor.
What is the medical term meaning recording of the strength of muscle contractions?
The medical term for recording the strength of muscle contractions is electromyography (EMG). This test involves placing small electrodes on the skin or inserting needles into the muscles to measure electrical activity during muscle contraction and at rest. It is often used to diagnose nerve or muscle disorders.
What is the purpose of EMG?
EMG is performed most often to help diagnose different diseases causing weakness. Although EMG is a test of the motor system, it may help identify abnormalities of nerves or spinal nerve roots that may be associated with pain or numbness.
