Top Features

1) Portability and Flexibility

Most EMG systems have a variety of uses, so the ability to use it on the move or for multiple test types can be crucial. Because of this, having an EMG machine, like the TECA Synergy N2 EMG Machine, that’s adaptable and features a  laptop computer is highly recommended.

2) A Large Powerhouse

On the other hand, if your exam room is more conducive to a stationary operation, a larger, more powerful EMG, such as the Cadwell Sierra II Wedge EMG System, may be better suited for your needs. Capable of accommodating almost any need, larger units boast most of the features of portable units in a single-room, rooted format.

3) Online Reports

The accessibility and readiness of results and reports can set an EMG system apart from the competition. From online access, to customizable reports, and immediate access to results, choosing an EMG system, similar to the Cadwell Sierra II Wedge EMG System, with a state-of-the-art reporting system is one of the best choices you can make.

4) Faster Testing

The faster testing can occur, the faster your patients can be diagnosed, making this one of the most important features you can find in an EMG system. With this in mind, making sure that you choose an EMG system, like the TECA Synergy T2X NCS EMG Machine, that has all the bells and whistles necessary is one of the most important aspects to consider when making a purchase.

5) Electrical Stimulator Probe

Patient comfort is of the utmost importance when using an EMG system. Machines such as the Nicolet EDX EMG/NCS/EP/IOM System, that come with the right electrical stimulator probe make it easy for you to ensure that your patient will be comfortable throughout the entire procedure and that you’ll get the most accurate results possible in the process.
