Electromyography is a highly used diagnostic technique in neurological and orthopedic fields.
Electromyography provides information both for the peripheral nervous function and skeletal muscles.
The main purposes of electromyography are:
–The analysis of muscle activity at rest during voluntary activation
–The study of nervous, motor and sensitivities.
It is performed through a needle electrode, it is a fairly invasive examination because the needle electrode is inserted into the muscles of the examination. The evaluation is done in three steps.
Thanks to the electromyography, it is possible to check if there are functional alterations to the components of the motor unit and, by evaluating the various alterations, it is possible to define the type of damage more clearly.
Electromyography is mainly indicated. For example, in:
-Compression neuropathies (carpal tunnel syndrome)
