Legend Series Stim
OPERATION
Pain Management
The management of post-traumatic, post-operative or chronic intractable pain associated with many areas of the body can be a
difficult task. Models 2S and 4S of the Intelect Legend Series Stim provide two waveforms and many parameter settings to manage
pain.
Two waveforms are available for Pain Management therapy: Interferential and Premodulated.
Interferential
The Interferential waveform consists of two channels, each with a sinusoidal waveform; one of fixed frequency and one of variable
frequency.
When the four electrodes are positioned so that the two channels cross each other, the two waveforms mix within the tissue to
produce a train of pulses whose frequencies and amplitude are dependent on the sweep mode, beat frequency and amplitude
settings, respectively. Press the Interferential button to select this waveform.
Ch. Select
controls the method for setting amplitude. The Both Channels mode changes intensity equally. The Channel 1 option
changes ONLY channel one and the Channel 2 option ONLY changes channel two. This is helpful when you need to balance the
output between channels.
When you highlight
Amplitude Modulation
and press the
enter
button, 3 options are displayed. They are 40% Scan (default), 100%
Scan and Static (no scan).
Scan Percentage
is the percentage of decrease from the maximum amplitude. Scan is amplitude modulation, expressed as a
percentage of the amplitude. The rhythmical varying of the amplitude of each channel produces the perceived movement of the
Interferential field.
