1. INTRODUCTION
INTENDED USE
IF stands for Interferential Stimulation. IF is indicated for symptomatic relief of chronic
intractable pain.
The Flexistim IF is intended for use in both the Hospital and Home
Healthcare Environments.
Flexistim IF provides interferential therapy to treat conditions where inammation is a
problem such as Back Pain, Osteoarthritis, Rheumatoid Arthritis, Muscular Pain / Strain,
and Sports injuries, or where deep penetration of low frequency stimulation is required.
Flexistim IF produces a low frequency current treatment that uses two medium frequency
currents, which “interfere” with each other to produce a beat frequency that the body
recognizes as a low frequency energy source.
The aim is to overcome the problems caused by low-frequency currents, while maintaining
their claimed therapeutic effect. Unlike TENS, which delivers intermittent pulses to
stimulate surface nerves and block the pain signal, Interferential Current Therapy delivers
continuous stimulation deep into the affected tissue.
The actual stimulation is produced by crossing two alternating currents with medium
frequencies simultaneously to a targeted body region. As a result, these two currents will
superimpose to form a new low frequency current deep within the tissue.
FLEXISTIM IF FEATURES
Flexistim IF includes many of the features of a professional desk-top unit in a compact,
portable, battery operated device.
1. Power Supply
Removeable, rechargeable Li-ion battery, with option of operation through external mains
power adaptor.
2. Output
60mA Peak to Peak pure sinusoidal carrier wave with constant energy (modied constant
current) control and 40mA safety override for home use.
1 2
3. Flexible programmes
3 preset and 3 adjustable programmes give a wide selection of treatment options.
4. Memory
Flexistim IF allows you to save and recall a particular programme setting and has a
Usage Timer to record the time it has been used.
2. WARNING AND CAUTIONS
Contraindications:
1. Do not use this device on patients who have a cardiac pacemaker, implanted
debrillator, or other implanted electronic devices, because this may cause electric
shock, burns, electrical interference, or death.
2. Do not use this device on patients whose pain syndromes are undiagnosed.
Warnings:
1. Do not apply stimulation over the neck or mouth because this could cause severe
muscle spasms resulting in closure of the airway, difculty in breathing, or adverse
effects on heart rhythm or blood pressure.
2. Do not apply stimulation across the chest, because IFT currents penetrate deep into
the tissue and the introduction of electrical current into the chest may cause rhythm
disturbances to the patient’s heart, which could be lethal.
3. Do not apply stimulation over the pregnant uterus.
4. Do not apply stimulation over open wounds or rashes, or over swollen, red, infected,
or inamed areas or skin eruptions (e.g. phlebitis, thrombophlebitis, varicose veins).
5. Do not apply stimulation over, or in proximity to, cancerous lesions.
6. Do not apply stimulation in the presence of electronic monitoring equipment (e.g.
cardiac monitors, ECG alarms), which may not operate properly when the electrical
stimulation device is in use.
7. Do not apply stimulation when in the bath or shower.

9. Consult with your physician before using this device, because the device may cause
lethal rhythm disturbances to the heart in susceptible individuals.
10. Apply stimulation only to normal, intact, clean, healthy skin.
11. Using the device directly over metallic implants could cause the currents to focus
over a small area, causing tissue burns. If you have metal implants, do not place the
pads near, or across the implant, and adjust the intensity with care.
Precautions:
1. Since the effects of stimulation of the brain are unknown, stimulation should not be
applied across the head and electrodes should not be placed on opposite sides of the
head.
2. The safety of electrical stimulation during pregnancy has not been established.
3. Some patients may experience skin irritation or hypersensitivity due to the electrical
stimulation or electrical conductive medium (gel).
4. Patients with suspected or diagnosed heart disease should follow precautions
recommended by their physicians.
5. Patients with suspected or diagnosed epilepsy should follow precautions recommended
by their physicians.
6. Use caution when the patient has a tendency to bleed internally, such as following an
injury or fracture.

3. HOW DOES IFT WORK
Many users will be familiar with TENS, which delivers intermittent pulses to stimulate
surface nerves and block the pain signal. Unlike TENS, Interferential Therapy delivers a
continuous stimulation deep into the affected tissue.
IFT achieves this deep penetration by using a 4000Hz carrier wave to overcome the
skin impedance. TENS signals travel around the top 1cm of the skin surface. IFT signals
travel almost directly between the electrodes.
Interferential Therapy uses two medium frequency 4000Hz currents that ‘interfere’ with
each other to produce a beat frequency that the body recognises as a low frequency
energy source.
Unlike TENS, which delivers intermittent pulses to stimulate surface nerves and block the
pain signal, IFT delivers continuous stimulation deep into the affected tissue.
In addition to providing pain relief by the same mechanism that TENS uses, most
physiotherapists consider that IFT’s major role is to accelerate the inammatory or
healing rate.
IFT is believed to work by stimulating parasympathetic nerve bres to give increased
blood ow and oedema reduction and by passing currents across cell membranes; these
currents vary depending upon the tissue involved. By using particular frequencies in the
range, different systems within the body can be stimulated or used to increase the blood
supply, which in turn hastens the healing rate. IFT is used to treat almost any condition
where inammation is a problem. For example, sports injuries; arthritic conditions;
bruising and swellings, back pain, osteo-arthritis, rheumatoid arthritis, muscular pain.
Many practitioners use a “Sweep” treatment which uses constantly changing interference
pulse frequency. Practical clinical experience suggests therapeutic benets for these
sweeps in addition to those of conventional nerve stimulation.
The range of this beat frequency in the
Flexistim F is 1 to 160Hz

STEP 4: PLACEMENT OF ELECTRODES
Ensure wherever you intend to place the electrodes, the skin is clean and thoroughly
dry. Remove the electrodes from the clear plastic shield and position on your body
as required.
Life of the Electrodes:
The electrodes are water based and can dry out if left outside of the PVC storage bag.
If the electrodes lose their adhesive quality in this way, it is possible to reactivate their
adhesiveness by applying a ne spray of water.
Replace the electrodes when they stop sticking well. This can affect the efciency of the
unit and may lead to skin irritation.
STEP 5: READING
Read sections 11 to 16 and decide how to use the unit for the treatment.
NOTE: AFTER USE
Always ensure that the unit is switched OFF before removing the electrodes. After use,
return the electrodes to the clear plastic shields and seal them in the PVC bag. There is

9. FURTHER CLINICAL INFORMATION AND
TREATMENT PROTOCOLS
For further information and clinical references go to www.tenscare.co.uk, and look on
the Flexistim IF product page.
10. ELECTRODE PAD PLACEMENT
Ensure that intensity is zero before connecting electrodes.
Insert connection lead(s) into the sockets below the handle.
Rotate the body of the plug to lock the lead in place. Plug the lead pins into the
sockets in the pad pigtails.
To avoid damage, remember to rotate the plug to unlock it before removing
the lead.
Only pull the lead by holding the body of the plug.
The interferential electrical signal is created by the interaction of the signals from all four
pads (i.e. between the pairs of pads of each channel). So the pads need to be applied in
positions so that the signals from each channel cross over the point to be treated.
8.1 Choosing settings
IFT works in the same way a TENS, but penetrates much deeper into the body. So you
can use IFT with the same settings as the TENS programmes.
Many therapists believe, however, that IFT has additional effects and can be used to
reduce swelling and muscle tension. One of the leading textbooks says:
2Hz Around this frequency the metencephalins are stimulated which will result in
short term pain relief.
10Hz This frequency has a benecial effect on the immune system and tends to
make patients wakeful yet relaxed.
130Hz This frequency stimulates the production of endorphins and results in longer
term pain relief and some local anaesthesia.
1-100Hz This frequency sweep will increase the inammatory rate.
45-90Hz This frequency sweep will depress the sympathetic nervous system so
allowing increased activity of the parasympathetic system and increase the
blood supply.
8. PROGRAMMES
19 20
Programme table:
P1 Constant. The pulse frequency is selectable. 2-16-Hz
P2 2-10 Hz Sweep over cycle time
P3 2-100 Hz sweep over cycle time
P4 80-150 Hz sweep over cycle time
P5 The pulse frequency varies set LOW frequency to set HIGH frequency over
Cycle Time and back. The transition is ramping (triangular wave function).
P6 The pulse frequency varies from set LOW frequency to set HIGH frequency
over Cycle Time and back. The transition is abrupt (square wave function).
The two channels add and subtract
to create an interference pattern. In
theory this pattern looks like the cross
shaped diagram below. In real tissue
the pattern is difcult to predict and you
may need to adjust the pad positions
until you can sense the stimulation in
the correct area.
The diagrams on the following pages
show how pads can be placed in
various body areas.
They all follow the same principles.

11. CARE OF ELECTRODES
The electrodes that are supplied with your Flexistim IF are self-adhesive and can be used
several times. Skin must be allowed to breathe, so the electrodes should be removed
periodically. When not in use, the electrodes should be placed onto the clear plastic shield.
The condition of the electrodes has a direct effect on conductivity and therefore the
effectiveness of the treatment. When the electrodes start to lose their adhesive quality,
it is possible to reactivate their adhesiveness by applying a ne spray of water to the gel
side of the electrode. In time, this technique will not work, the gel will not reactivate and
new electrodes should be used.
GENERAL PAD ADVICE
• The electrode pads supplied are reusable but are for single patient use.
• In order to obtain the best conductivity through the pads always ensure that they are in
good condition and tacky.
• Before use make sure your skin is clean and dry.
• Peel the electrode pads from their protective plastic shield by holding and lifting one
corner of the pad and pulling. Do not pull on the pigtail wire of the pad.
• After use always replace the pads on the plastic liner and replace in the re-sealable plastic bag.
• If the pads dry out then it is best to buy a replacement pack of electrodes. In an emergency
it may be possible to restore some of the tackiness of the pad by adding a tiny drop
of water on each pad and spreading around. If too much water is added the pads will
become too soft then it is suggested in order to try to re-establish some adhesiveness to
place them sticky side up in a refrigerator for a few hours.
• In very hot weather the gel on the pads may become soft. In such cases place the
pads, still on their plastic liners and in their bag, into a fridge until they return to their
normal condition.
WARNINGS
Do not use any electrodes less than 50mm X 50mm.
Allergic reactions to the self-adhesive electrodes can occur even though they
are hypoallergenic.
• Do not apply to broken skin.
• Do not apply electrodes to areas with less than normal sensitivity. This could lead to
setting intensities at higher levels than intended.
