Electromyography (EMG) is a technique for analyze the activation signal of muscles. EMG is performed using an instrument called elettromiografo , to produce a record called an electromyogram. An electromyograph detects the electrical potential generated by muscle cells when these cells are mechanically active, and also when the cells are at rest.

The sequence of the various measurements is not fixed for each disease presented, but may vary based on the results obtained gradually.

The electromyographic study makes use of two stages: the Elettroneurografia (ENG) and the electromyography (EMG)

The ENG (Elettroneurografia) is the study of the neurophysiological parameters of nerve conduction . The conduct can be examined from a sensory or motor. In the first case (sensitive) measures the ability to provide information to higher centers collected from peripheral endings. In the second case (motor) measures the ability to send commands to the various muscles engines.

The EMG (electromyography) is the recording of electrical muscle.

Both methods allow you to:

• locate noise ratio (where is the problem and what structures are involved?)

• identify the underlying pathological process is .

• characterize the deficit .

• assess the seriousness of the deficit .

• monitor the course of the disease

• To provide a prognosis

• assess the effectiveness of therapies taken
