The NEW Neuromuscular Stimulator TOF monitor

Unique Features

The STIMPOD NMS450X Neuromuscular Stimulator TOF monitor has many unique features including, a Tri-axial accelerometer. This provides real-time feedback on the strength of contraction of the affected limb. The Stimpod is programmable to use the following methods of stimulation: Train of four, double burst, post titanic count modes. The contraction strength of each measure graphically displayed, provide calculated relevant ratios thus providing best practice

These fine movement differences detectable by utilizing accelerometry offer major advantages over gauging contraction strength visually or tactilely.

The only Neuromuscular Monitoring system available with both AMG and EMG sensor technology 


AMG offers the most cost-effective option to implement with a reusable sensor and versatile patient setup options enabling neuromuscular transmission monitoring of the hand, toe or face.

EMG is ideally suited for neuromuscular monitoring of surgeries where tucked hands and arms are required, with optimized performance through a patented, skin-like electrode.

The Stimpod NMS450X Tri-Axial accelerometer

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

Combined Nerve Mapping and 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. Because of this feature, we can ensure quick and precise nerve location.

This technology provides a cost-effective alternative to ultrasound techniques for determining anatomical deviations prior to needle insertion. The technique reduces the time of the procedure and provides favorable patient comfort and safety.

Charge Transfer Waveform of our Neuromuscular Stimulator TOF monitor:

The STIMPOD displays a real-time graphical representation of the actual waveform delivered.

The displayed waveform serves as a quick reference for excessive impedance (> 20kOhm) in the circuit. The waveform will indicate if the pulse delivered according to the settings. If the waveform is not square, this will immediately indicate excessive impedance in the circuit and all elements in the circuit i.e. ECG electrodes and/or skin condition needs to be re-assessed before nerve location can be successfully completed.

NEW FEATURES for the Stimpod NMS450X Neuromuscular Stimulator TOF monitor

  • OneTouch NMT™ monitoring mode for complete case monitoring at the touch of a button

The Stimpod Nerve Mapping Probe is 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.

Proximity Indicator
Visual and audible feedback is given when the target current- and pulse width ranges are reached indicating probable nerve proximity.

The Proximity Indicator provides a safety mechanism that prevents the user from getting confused with the current settings at different pulse widths. Prior to performing your peripheral nerve block, this unique indicator will provide an indication of nerve proximity.

Non-Linear Current Adjustment
In this current adjustment mode, the user can pre-program 20 different current and pulse width settings.

When adjusting the adjustment wheel the STIMPOD Nerve Stimulator will only scroll through the pre-programmed Current and pulse width settings. (The default settings are calculated to facilitate the non-linear nature of the current intensity versus the distance from the nerve.)*
