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 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.
14
INTELECT LEGEND STIM USER MANUAL
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.

Muscle Contraction
Two waveforms are available for muscle contraction therapy; Twin-Peak High Volt and Russian. The appropriate selection of a
waveform for relaxing muscle spasms, increasing local circulation, re-educating muscles that have atrophied from disuse or injury,
or to maintain or improve joint range of motion can be difficult. Both models 2S and 4S of the Intelect® Legend Stimprovide the
needed waveforms to address these clinical problems.
High Volt
High Volt stimulation has output ranges between 300 and 500 volts. True Twin-Peak High
Volt is designed to deliver very short-duration pulses, which are very low in pulse charge. High
Volt is available through channel 2 and 4 on the model 4S and channel 2 on the model 2S.
Method gives you the option of delivering High Volt to the patient either by Pads (default) or
Probe application.
Polarity of the active electrode can be changed from Positive (default) to Negative by
selecting POLARITY and pressing the ENTER button. When Positive (default) polarity is selected,
the Red leadwire is positive polarity and the Black leadwire is negative polarity. IF YOU
SELECT NEGATIVE POLARITY, the Red leadwire becomes negative polarity and the Black
leadwire becomes positive polarity.
Cycle Time parameter controls the on/off cycle time of the current. There are 7 available
options: 5/5, 10/10, 10/20, 4/12, 10/30, 10/50 and Continuous (default).
Method
Sweep is frequency modulation of the High Volt current. When you select SWEEP and press the ENTER button, 4 options are displayed.
They are Continuous (default at 100 pps), 1-10 Hz, 80-150 Hz and 1-150 Hz. The Continuous option allows you to select a continuous
fixed frequency from 1-120 pps.
Frequency is the number of pulses per second of the waveform. To change the Frequency select FREQUENCY and press ENTER,
then use the UP or DOWN arrows to change the frequency, from 1-120 pps.

INTELECT LEGEND STIM USER MANUAL
Ramp controls the amount of time required to bring the stimulation up to the selected
amplitude. When you select RAMP and press ENTER, 4 options are displayed. They are 0.5
seconds, 1 second, 2 seconds (default) and 5 seconds.
Display provides two options of viewing output. The options are Voltage (default) and Peak
Current. The ability to assess peak current can help determine tissue response, and an
indication of impedance to current at the electrode skin interface.
Russian
The Russian current is a 2,500 Hz sinusoidal carrier wave, interrupted to create pulse trains or
"bursts." The number of bursts per second is determined by the burst
frequency and the length of the bursts is determined by the duty cycle.
Ramp
Mode provides three methods of treatment including Single channel application, Reciprocal
application where stimulation alternates between agonists and antagonists and Co-Contract
where the timing of stimulation can be coordinated through two channels to simultaneously
co-contract agonist and antagonist or differing sections of a larger muscle group.
Cycle Time parameter controls the on/off cycle time of the current. There are 7 available options:
5/5, 10/10, 10/20, 4/12, 10/30, 10/50 (default) and Continuous.
The Burst Frequency is the number of bursts per second (bps) and the available range is 20 bps
to 100 bps.
Ramp controls the amount of time required to bring the stimulation up to the selected
amplitude. When you press the Ramp button it will toggle between .5 seconds,
1 second, 2 seconds (default) and 5 seconds.
Mode
INTELECT LEGEND STIM USER MANUAL
Duty Cycle is the ratio of on time to total time of the burst and is expressed as a percentage.
