Microcurrent
Modality Information
Microcurrent is low-volt pulsed microamp stimulation which has been used for symptomatic relief of chronic intractable
and post-surgical pain. With the Dynatron Solaris Plus both attended or unattended Microcurrent therapy can be applied.
Unattended therapy is delivered using electrodes. Attended therapy is delivered using the optional Dynatron hand-held
MultiStim probe.
Due to the very low frequencies generally associated with a Microcurrent treatment, the current is commonly not felt by the
patient. However, Microcurrent at high intensity settings or during a probe treatment can sometimes be felt by the patient
and may even be uncomfortable. During a probe treatment, this may be the result of current being concentrated at a very
small area.
As with all forms of electrotherapy, current density is dependent upon the current setting, the intensity setting, size, and type
of electrodes used, and conductance. Higher current density increases the possibility for patient discomfort. The current
density can be reduced by decreasing the amount of current (intensity) or increasing the area through which the current is
being delivered. The area can be increased by using larger electrodes and/or making sure that the total area of the electrode
is actually delivering current.
Microcurrent Waveforms
Three different output waveforms (polarities) may be
selected with the Dynatron Solaris Plus. Positive and
Negative selections are available for both probe and
electrodes. An additional bipolar option is available when
using electrodes. With Conductance Bar turned off, the
first two are unipolar square waves having a monophasic
pulse at a 50 percent duty cycle (equal on and off times).
In the illustration, the first unipolar waveform has negative
polarity only, and the second has positive polarity only.
The third waveform is a bipolar (negative and positive)
square wave with a 50 percent duty cycle.
