| WHAT IS EDT? |
|
| Electrodiagnostic Testing (EDT)
studies measure the speed and
degree of electrical activity in
your muscles and nerves. Injuries
and diseases that affect nerves
and muscles can slow or change
the movement of this electrical
activity. If you have pain,
numbness, tingling or weakness in
your hands and arms, an EDT
study which measures these
changes can be an important tool
for your physician to make an
accurate diagnosis of your
condition. |
| |
|
| There are two EDT studies which
are most commonly used: |
 |
Electromyography (EMG) |
|
Nerve conduction studies (NCS) |
|
| |
|
| EMG studies record the level of
electrical activity in the muscles.
NCS measure the speed at which
the electrical signal travels along
the nerve. |
