The Myotest provides train-of-four, single twitch (1 and 10 s), and tetanic stimuli.
It features a unipolar constant current impulse with adjustable amplitude (0-40 mA).
Powered by standard batteries, offering 200 hours of effective use.

Main Results:

The device is designed for ease of use and clear interpretation of responses.
Effective for tetanic and post-tetanic stimulation, enhancing diagnostic capabilities.
Consistent power delivery and adjustable parameters ensure reliable performance.

Conclusions:

The Myotest is a versatile and user-friendly nerve stimulator.
Its features facilitate accurate neuromuscular monitoring in clinical settings.
It represents an advancement in tools for assessing neuromuscular function.
