The STIMPOD NMS450 Nerve Stimulator includes a Tri-axial accelerometer which provides real time feedback of the strength of contraction of the affected limb (Train Of Four, Double Burst and Post Tetanic Count modes only). The strength of each measured contraction is displayed graphically and the relevant ratios are calculated and also displayed.


The fine movement differences that can be detected by utilizing accelerometry offer major advantages over gauging contraction strength visually or tactilely.


Tri-axial accelerometry calculates the movement vector of the contraction in three dimensions.  This negates the need for calibration as is the case with one-dimensional accelerometers, and reduces the setup time of the procedure.


Combined Nerve Mapping & Nerve Location:

Auto sensing technology provides a solution for simultaneous nerve mapping and nerve location. The Stimpod monitors whether the mapping probe or needle touches the patient and adjusts the current range accordingly, ensuring quick and precise nerve location.

The Stimpod Nerve Mapping Probe was designed to enable transcutaneous nerve mapping at higher currents (to a maximum of 20mA), whilst the tip offers a contact surface small enough to ensure effective discrimination.
