NexWave
Indications for Use
Interferential Current (IFC)
Indications
·
Management and symptomatic relief of chronic intractable, post - traumatic and
post - surgical pain.
Contraindications
·
This stimulator shall not be used on patients with a cardiac demand pacemaker.
·
Electrodes shall not be placed so that current will be applied to the carotid sinus
(neck) region or transcerebrally (through the head).
·
This stimulator shall not be used whenever pain syndromes are undiagnosed until
etiology is established.
Warnings
·
When using the separate external power supply, this medical electrical device
does not incorporate a power switch to isolate the system from the AC mains.
Unplug the power cord of the AC adapter from the AC mains outlet in order to
positively disconnect from the AC mains. Ensure that the AC outlet is easily
accessible.
·
This device is capable of generating current densities for electrodes exceeding 2
mA RMS/cm
2
which may require special attention of the operator.
· Do not exceed 0.5 W/cm
2
with recommended electrodes, assuming a load of 1000
Ω.
·
1” round: Maximum stimulation setting = 50 mA
· 2” round: Maximum stimulation setting = 50 mA
·
2” square: Maximum stimulation setting = 50 mA
·
Output waveform/power information:
When delivering stimulation energy, the NexWave in IFC mode is a constant
current output device. Therefore, its output voltage, current, and power are
dependent upon the load as well as the pulse width and frequency of the output
waveform. Using the supplied AC adapter to power the unit, the maximum peak
voltage that the NexWave can produce is 50 V (1000 Ω load). The maximum peak
current that the NexWave can produce is 50 mA (1000 Ω load). The maximum
output power that the NexWave can produce is 2.5 W per channel into a 1000 Ω
load, 5 W total.

Radicular Back Pain - Sciatica
ELECTRODE PLACEMENT
Place one set of electrodes for one channel close to the spine and follow the pain route
as shown below. The other channel electrodes should be placed to follow pain route
down the leg when pain is felt below the low back as shown below.
