For such polarization setting red plug is a
negative electrode and black plug is a
positive electrode. Warning means that such
a setting is the reverse of commonly
accepted way of marking polarity.
ALT

Rectangular pulse currents
Rectangular pulse current consists of pulse sequence of rectangular shape and independently adjusted times
of pulse and pause. It may consist of a series of pulses with amplitude modulation, where the intensity of
consecutive pulses in the series gradually increases and decreases (training program). As a result,
electrostimulation parameters can be individually adjusted, depending on the patient's condition and the
purpose of the treatment.
This current is used to stimulate properly innervated muscles. It is also applied in electrodiagnostics to determine
the I/t curve.
