Current form [DC (direct) /PC (pulsed)]
The Fischer
®
gives you the option to
choose between direct current or
pulsed current treatments. The direct
current setting is symbolized by a solid
bar; pulsed by a broken bar (pictured
right).
Direct current (DC)
is more effective than pulsed current based on experience.
With direct current, power slowly ramps up and maintains the maximum value
throughout the treatment.
Pulsed current (PC),
on
the other hand, it’s perceived as being more
comfortable because patients can tolerate higher currents. However, pulsed
current is not as effective because you is only receiving a small portion of the
treatment at the maximum value. Instead of maintaining the maximum value
throughout the treatment, pulsed current fluctuates the current up and down.
Put it this way:
what’s the more effective way of driving down the highway?
Accelerating to 65 mph and keeping a steady speed until you reach your
destination and then slowing to a stop? (direct current) Or accelerating to 100
mph, then decelerating down to 0, then re-accelerating back up to 100, all the
way down the highway? (puled current) Sure, you were technically “going faster”
in our pulsed current metaphor (100 mph vs 65 mph), but did it really get you to
your destination any faster?
Pulsed current should only be selected in those cases where direct current is
perceived as being too painful even at relatively low current values, or if your
skin is highly sensitive. Additionally, patients who are seeing a reduction in
sweating may choose to switch to pulsed current for their regular maintenance
sessions.
Direction of Current Flow [E1/E2]
We recommend starting out in the
AUTO mode. This will automatically
switch the polarity from positive to
negative between the two silicone-
graphite electrodes (labeled E1 & E2).
