WAVEFORMS - DEFINED
The amplitude, pulse rate, pulse
width and the mode selectors
operate independently of each
other, but interact to achieve
the desired result. As individual
syndromes differ, the controls
are adjusted to a setting which
gives optimal comfort and pain
relief.
Amplitude: The amplitude con-
trols the intensity and the depth
of the pulse. The higher the
amplitude, the higher the pulse
peak and the stronger the pulse.
If the electrodes are placed over
scar or over adipose tissue, care
should be taken that the am-
plitude is set at a level that is
both effective for the patient’s
treatment and does not cause the
patient any discomfort. Set the
QuadStar® Elite amplitude
to the appropriate level accord-
ing to patient comfort. There is
no benefit to painful stimulation.
.
Pulse Width: The pulse width
governs the width of the pulse.
A comfortable sensation cover-
ing the injured area is the main
purpose of the pulse width. The
pulse width has been fixed (pre-
set) in the QuadStar®Elite In-
terferential Modality and HVPS
Modality.
Pulse Rate: The pulse rate
controls the number of pulses
emitted through the electrode to
the skin.
The pulse rate is also referred
to as:
1. Frequency
2. Cycles per second (c.p.s.)
3. Pulses per second (p.p.s.)
4. Pulse Pairs per Second
(p.p.p.s, High-volt
modality only)
A Hertz (Hz) is a unit of fre-
quency equal to one pulse per
second, e.g. 50 Hertz = 50 p.p.s

INTERFERENTIAL SAFETY INFO.
Federal law (USA) restricts this device to sale or use by, or on the order of, a
physician so licensed by the state. For external use only. Keep out of reach
of children.
Indications: Interferential Stimulation is used for symptomatic relief and
management of chronic (long-term) intractable pain and/or as an adjunctive
treatment in the management of postsurgical and post-traumatic acute pain.
Contraindications: Interferential stimulation devices can affect the opera-
tion of demand-type cardiac pacemakers. TENS is not recommended for
patients with known heart disease without a physician's evaluation of risk.
Do not stimulate over the eyes or carotid sinus nerves. Do not apply Interfer-
ential stimulation devices for 1. undiagnosed pain syndromes until etiology is
established, 2. electrode placement that causes current to flow transcerebrally
(through the head).
Warnings: This device should be used only under the continued supervision
of a physician. Interferential stimulation is ineffective for pain of central
origin, (i.e. appendicitis, hepatitis). Interferential stimulation is of no cura-
tive value; it is a symptomatic treatment which suppresses pain sensation
which would otherwise serve as a protective mechanism on the outcome of
the clinical process. Safety of Interferential stimulation devices for use dur-
ing pregnancy or delivery has not been established. Electronic equipment
such as EKG monitors and EKG alarms may not operate properly when In-
terferential stimulation is in use. This device should not be used over metal
implants or sleep apnea monitors.
Precautions: Skin irritation may occur under electrodes in isolated cases
following long-term application. Consult physician if skin irritation devel-
ops. Avoid adjusting controls while operating machinery or vehicles. Turn
the stimulator off before applying or removing electrodes. Long-term stimu-
lation at the same electrode site may cause skin irritation. Use only for the
specific pain problem prescribed by the physician. Effectiveness is depen-
dent upon patient selection. Do not immerse device in water or other liquids.
Adverse Reactions: Possible allergic reaction to tape or gel. Possible skin
irritation or electrode burn under electrode.

BioMedical Life Systems, Inc.’s
Model QuadStar®Elite offers the latest
advances in Interferential Stimulation
Treatment. Interferential Stimula-
tion is different to that stimulation
received from using TENS or NMS.
In TENS and NMS stimulation, low
frequencies or pulses per second are
used over a wide area to achieve pain
relief. Most stimulation is directly
under the electrodes and radiates out.
In Interferential therapy, two medium
frequencies of different cycles are
used in such a way that they criss-
cross, delivering a low frequency at a
specific point.
The QuadStar®Elite has two types of frequency. One that is fixed at 4000
cycles per second and the other which is adjustable within the range 4001 to
4150 cycles per second. This in combination allows one to stimulate from 1
to 150 pulses per second, at a specific point.
The QuadStar®Elite has four channels, which can be used with two, four or
eight electrodes, and has four different stimulation patterns. At low levels
of stimulation the QuadStar®Elite‚stimulates the sensory nerve cells that are
used for pain relief.

Insertion of Lead Wires and
Electrodes
Insert pin connector of lead wire
into pig tail of electrode. (When
inserting or removing pin con-
nector, grasp connector—not
lead wire—to prolong lead wire
life.) For some electrode loca-
tions, it may be preferable to
insert the pin connection before
attaching the electrode to the
skin. Follow the directions on
the package of electrodes for
further information.
Beginning Stimulation:
When satisfied with all parame-
ters and nothing on the screen is
blinking or “active,” press keys
12, 13, 14 and 15 in the upward
direction repeatedly to set de-
sired intensity. Doing so starts
the stimulation through

10
INTERFERENTIAL OPERATING INSTRUCTIONS
the electrodes to the skin, and
controls the intensity of the
device. Do not press buttons
12-15 until the user is ready for
stimulation. In full interferential
mode, either button of a channel
pair (1&2 or 3&4) will change
the intensity of both channels.
The LCD display will begin
to show bars under the corre-
sponding channel to indicate the
intensity is being adjusted and
will remain illuminated.

Federal law (USA) restricts this device to sale or use by, or on the
order of, a physician so licensed by the state. For external use only.
Keep out of reach of children.
Indications: External electrical neuromuscular stimulation using
biphasic output is indicated as therapeutic adjunct for: prevention
or retardation of muscle disuse atrophy; relaxation of muscle spasm;
muscle reeducation; maintaining and increasing the range of motion;
increasing local blood circulation and as immediate postsurgical
stimulation of calf muscles to prevent venous thrombosis.
Contraindications: Powered muscle stimulators should not be used
on patients with cardiac demand pacemakers.
Warnings: The long-term effects of chronic electical stimulation are
unknown. Stimulation should not be applied over the carotid sinus
nerves, particularly in patients with a known sensitivity to the ca-
rotid sinus reflex. Stimulation should not be applied over the neck or
mouth. Severe spasm of the laryngeal and pharyngeal muscles may
occur and the contractions may be strong enough to close the airway
or cause difficulty in breathing. Stimulation should not be applied
transthoracically in that the introduction of electrical current into
the heart may cause cardiac arrhythmias. Stimulation should not
be applied transcerebrally. Stimulation should not be applied over
swollen, infected, or inflamed areas or skin eruptions, e.g., phlebitis,
thrombophlebitis, varicose veins, etc. Stimulation should not be ap-
plied over, or in proximity to, cancerous lesions.
NMS SAFETY INFORMATION

NMS SAFETY INFORMATION
Precautions: Safety of powered muscle stimulators for use during
pregnancy has not been established. Caution should be used for pa-
tients with suspected or diagnosed heart problems. Caution should
be used for patients with suspected or diagnosed epilepsy. Caution
should be used in the presence of the following:
a.When there is a tendency to hemorrhage following acute trauma or
fracture;
b. Following recent surgical procedures when muscle contraction
may disrupt the healing process;
c. Over the menstruating or pregnant uterus; and
d. Over areas of the skin which lack normal sensation.
Some patients may experience skin irritation or hypersensitivity due
to the electrical stimulation or electrical conductive medium. The
irritation can usually be reduced by using an alternate conductive
medium, or alternate electrode placement. Electrode placement and
stimulation settings should be based on the guidance of the prescrib-
ing practitioner. Powered muscle stimulators should be used only
with the leads and electrodes recommended for use by the manufac-
turer. Portable powered muscle stimulators should not be used while
driving, operating machinery, or during any activity in which invol-
untary muscle contractions may put the user at undue risk of injury.
Adverse Reactions: Possible allergic reaction to tape or gel. Pos-
sible skin irritation or electrode burn under electrode.

Neuromuscular Stimulation
(NMS) is the use of electrical
stimulation on muscle groups to
contract and reeducate muscles.
Some of the uses of NMS are as
follows:
1. The Prevention or Retarda-
tion of Muscle Disuse Atrophy:
Muscle disuse atrophy is a re-
duction in muscle contraction
and size due to disuse/lack of
use resulting from prolonged
impairment or joint immobility
from surgery or injury.
2. Relaxation of Muscle
Spasms: Muscle spasms often
occur in areas of localized pain
and tenderness. Stimulation is
used to fatigue the spasmodic
muscle.
3. Increasing Local Blood
Circulation:Rhythmic muscle
contraction helps improve local
blood circulation.
4. Immediate Post surgical
Stimulation of Calf Muscles to
Prevent Venous Thrombosis:
The use of NMS or EMS to
increase local blood circulation
assists in the prevention of ve-
nous thrombosis.
