OPERATION
Intelect® Legend Series Stim
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.

Amplitude Modulation/Scan Percentage
When you highlight Beat Frequency and press the enter button, 5 options are displayed. They are 1-10 Hz, 80-150 Hz (default),
1-150 Hz, Variable and Fixed.
The Variable option allows you to select a Low Beat frequency from 1-200 Hz and a High Beat frequency from 1-200 Hz. To make
changes in the Variable frequency, highlight variable and press the enter button. To change the Beat Low frequency, use the down
arrow to highlight Beat Low and press enter. Use the up/down arrows to adjust the frequency. Press enter to accept.
Beat Low describes the lowest frequency in the range of a sweep mode. For example when using a sweep of 80-150 Hz, 80 Hz is the
lowest frequency.
Beat High describes the highest frequency in the range of a sweep mode. For example when using a sweep of 80-150 Hz, 150 Hz is
the highest frequency.

Premodulated
Premodulated is an amplitude modulated sine wave. This waveform is similar to the beat
frequency created by Interferential current. In some cases, Premodulated therapy provides a
good alternative for Interferential treatment especially when treating areas of the body where
four electrodes can not be utilized.
Cycle Time parameter controls the on/off cycle time of the current. There are 2 available
options, Continuous (default) and 5/5.
When you highlight Beat Frequency and press the enter button, 5 options are displayed.
They are 1-10 Hz, 80-150 Hz (default), 1-150 Hz, Variable and Fixed.
Cycle Time
The Variable option allows you to select a Low Beat frequency from 1-200 Hz and a High Beat
frequency from 1-200 Hz. To make changes in the Variable frequency, highlight variable and
press the enter button. To change the Beat Low frequency, use the down arrow to highlight
Beat Low and press enter. Use the up/down arrows to adjust the frequency. Press enter to
accept.
Fixed Option
Beat Low describes the lowest frequency in the range of a sweep mode. For example when
using a sweep of 80-150 Hz, 80 Hz is the lowest frequency.
Beat High describes the highest frequency in the range of a sweep mode. For example when
using a sweep of 80-150 Hz, 150 Hz is the highest frequency.
The Fixed Option, allows you to select a fixed frequency from 1-200 Hz. To make changes to
the Fixed frequency, highlight fixed and press enter. Use the up/down arrows to adjust

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 Series Stim provide 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).

the up or down arrows to change the frequency, from 1-120 pps.
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.

OPERATION
Intelect® Legend Series Stim
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.
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.
Duty Cycle is the ratio of on time to total time of the burst and is expressed as a percentage.
The options are 10%, 20%, 30%, 40% and 50% (default).

HAND HELD PROBE (Optional)
HIGH VOLT Probe
The High Volt probe is used to deliver stimulation manually. Select the High Volt waveform then simply plug the Black lead wire into
the connector of the Probe. The Red lead wire from the same channel should be attached to an electrode and placed near the
treatment site. The default polarity for High Volt is positive. When using this setting, the Red lead is positive and the Black lead is
negative.
• Select the parameters you wish to change then press the start button to begin treatment.
NOTE: Place the ground electrode as close to the treatment site as possible where it will not interfere with placement of the active
electrode; for example, do not place the ground electrode on the leg if you are treating the arm.
