1. How does a TENS work?
T.E.N.S. is an acronym for Transcutaneous
Electrical Nerve Stimulation. With the development
of modern medicine doctors and scientists have perfected
the use of electric pulses to treat and eliminate
pain. TENS units use electro frequency at about 80
to 90 MegaHertz. According to doctors and medical
professionals the TENS device is the most highly effective
treatments for pain relief. A TENS unit is a device
that transmits small square electrical pulses to the
electrodes, which transmit this electrical pulse to
the underlying nerves. The fundamental components
of a TENS unit are the electrodes, a highly advanced
computer chip, and an electrical battery source. The
small amount of electricity is transmitted through
the computer component then to the electrodes, which
transmits the electrical waveform to the underlying
nerves. The user can personalize the pulse frequency,
which is the strength of the electrical current given
to the electrode. The strength of electric current
is measured in megahertz. The user can also adjust
how long each pulse width is. This pulsation effect
gives a cycle of higher and lower electric wavelengths.
This measurement between the wavelengths is measured
in time by microseconds. The strength of the pulse
and the width on duration of that pulse are the two
main adjustments found on TENS units. Two more features
that you can get on a TENS unit are settings for a
burst mode and a modulation mode. A burst mode changes
the time and duration of the pulse and makes a series
of seven quick pulses followed by a rest. This cycle
repeats itself two times every second. The modulation
mode changes the time and duration of the pulse with
but uses a combination of burst and the continuous
features that were preset, (pulse strength and with).
This setting is often used for long-term users to
confuse the pain receptors in the brain so that it
cannot learn to ignore these pain-relieving frequencies.
2. How can I get a TENS unit?
You will need a prescription from a doctor –
chiropractor, obstetrician, Pediatrician, internal
medicine doctor or other doctors. Simply mail or fax
your prescription to us and we will ship you your
TENS.
3. How long will it take for my TENS to help
my pain?
It takes approximately 30 minutes or less to feel
the effects. Some people Prefer to use their TENS
all day or for several hour at a time. Our AUTOMATIC
TIMER TENS can be used to help you go to sleep.
Every individual has different needs. If you have
two different areas of pain you may use two sets of
electrodes (each have two pads) so that your TENS
can treat your pain simultaneously.
4 . How do I use my TENS?
We include directions with your Tens Unit. Using
a TENS is very easy. It is portable and may be clipped
to a belt, shirt pocket, bra or other clothing. Depending
on the level of pain for a certain day the Tens Device
may be adjusted for different intensities. Please
follow your Medical professionals instructions on
how to use your unit that his specific to your needs.
5 . Is using a TENS dangerous?
Absolutely not. Our TENS are FDA (Food & Drug
Administration) approved and are completely safe to
use when used properly. The only area of restriction
for using a TENS is that it should never be used on
your head or face area or if you have a pacemaker.
If you have pain in your face or head area you may
use one of our MICRO CURRENT ENS. This unit is designed
to treat migraine headaches.
6. Are there side effects?
Definitely not. Unlike prescription or over the counter
drugs, TENS are side
effect free when used as directed from your medical
professional. Most Pain Control medicines are narcotics,
which are highly addictive especially if used for
a substantial amount of time. Many people who suffer
from long-term pain and are taking pain control medicines
have developed a dependence on these narcotic medicines.
That is one of the many reasons why people use TENS
instead of narcotic medicines. By using our state
of the art TENS, you may continue to lead a more active,
less painful lifestyle.
7. Will using a TENS hurt or give me more
pain?
Absolutely not. If our Tens Units are used as directed
your pain may be reduced. You will feel a tiny tingling
sensation which is a minor to no discomfort at all.
This is because it has a high frequency, which means
the stimulation is approximately one hundred times
per second. Using our Tens your pain should be lessened
or disappear.
8. How do I get additional electrodes or
batteries?
The average monthly use of a Tens Units accessories
are two packs of electrodes (8 electrodes) and one
9V battery.
If you sign up for the automatic
reorder program you will receive a discounted
price on electrodes and batteries. This program simplifies
the process of replacing your electrodes and batteries.
If you are using you unit because of an accident such
as a workers comp claim then most insurance companies
will pay for this program as long as you are in your
recovery phase. If you would like to see if you are
eligible for this please fill
out this form.The replacement items are sent directly
to your home or office.
9. Will you accept my health insurance?
We accept certain
health insurance companies. We do not accept HMO’S
or Medicare. Please use our insurance
form. (CLICK HERE TO FILL-OUT OUR SHORT FORM).
10 . Will you accept Medicare or Medicaid?
No. Medicare will only pay for a rental tens unit.

payment for Tens Units we can not accept payment by
medicare.
11. What is Tensunits.com's warranty?
It is very uncommon for our Tens units to experience
problems. They are very durable and reliable. In most
cases the reason a unit stops working is because of
water damage. Our warranty DOES NOT
cover water damage. It is very easy for out tech people
to diagnose this cause when the unit when it is inspected
and it will not be fixed or replaced free of charge.

We guarantee out TENS
for five years. This is a pro-rated
warranty and the item will be replaced free of
charge for the first year. Each year after this
the item will be replaced with 20% pro-rated discount
from the original price. (example for a $100 item)
Example $100 x 20% = $20. The replacement cost
for the second year would be $100 -$20 = $80.
For the 3rd year $60, 4th $40 and so on. |
If for some reasons your unit has a problem and needs
to be replaced repaired. Please use the following
guidelines in the RMA Section.
12. Who should use a TENS UNIT?
TENS should be used only under the continuing supervision
of a physician. Some of the most common doctor reccomended
uses for TENS are: Rheumatoid Arthritis, Multiple
Sclerosis, Cancer, Bursitis, Postoperative pain back
pain, foot, knee, sciatica, sprains, carpal tunnel
syndrome, bursitis, labor pain (not before nine months),
and many other types of pain. Non pain uses are for
swollen joints, spasms, relaxes muscles, and overall
body relaxation.
People who
should not use TENS:
According to medical Doctor Chris Wells, 30 percent
of North Americans suffer from chronic pain, and many
believe nothing can be done to help them. With our
state of the art TENS UNIT, pain sufferers can be
helped. According to Dr. Patrick D. Wall, “Twenty
million Americans are in pain from arthritis; 30 million,
of whom are wholly or partially disabled, have endured
spells of persistent back pain at some time in their
lives; and millions more are in pain from cancer,
angina pectoris, and other causes. No single sickness
comes anywhere near equaling pain in the sheer scale
of incidence. It is a silent epidemic!” (1)
If you have tried conventional methods and they have
not given you pain relief then using our TENS UNIT
may give you effective pain
relief.
13. I have migraine headaches. What can I
use to relieve my pain?
You can use our MICRO CURRENT TENS. This unit is
excellent for head, face and neck pain. Please follow
your doctors recommendations.
14. Can TENS be used for for pregnant women
and during labor?
Yes, more and more expectant mothers are using our
TENS unit during their last trimester (full-term)
for delivery. Now, thanks to out TENS many women have
experienced pain relief during labor. Please check
with your doctor for proper treatment during pregnancy.
15. How does Interferential therapy differ
from TENS?
Interferential differs from EMS and TENS because
it delivers stimulation deep into the affected tissue.
Interferential uses the interference of two separately
generated sinusoidal currents applied to the body
simultaneously. It is 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 range of this frequency is usually 1-250 Hz. The
body itself produces low frequency currents between
1 and 256 Hz. These currents are produced across the
cell membranes by ionic exchange, and they will vary
depending upon the tissue involved. By using frequencies
in this range, different systems within the body can
be stimulated.
Interferential Units are most often prescribed by
medical professionals for more serious injuries and
for treatment after surgery. Interferentials are much
more delicate in the way that they use the low electrical
frequencies.
16. How does a TENS differ from a EMS (Electrical
Muscle Stimulator)?
EMS Muscle stimulators are used to relieve pain,
reduce spasms and edema, tonify weak muscles, and
assist the healing process, muscle tension, stiffness
in joints or back areas, increasing motion restricted
from disuse or atrophy and for increasing local blood
circulation. EMS Units run at from 1 to 130 Mega Hertz.
TENS is designed to help relieve certain types of
chronic and acute pain. An EMS is designed to treat
more of the muscle area than the nerves. This can
help reduce swelling and muscle inflation which can
have a negative effect when a strained muscle can
pull joints out of place.
17. What other electrical
devices use electric current on the body for treatment?
Yes. Muscle stimulators relieve pain, reduce spasms
and edema, tonify weak muscles, and assist the healing
process, run at from 1 to 130 Hz. TENS units are used
to block pain run at about 80 to 90 Hz. Interferential
Therapy units are a type of muscle stimulator run
at 3000 to 4000 Hz. Bio Feedback instruments used
to modify behavior and retrain the nervous and muscular
systems, run from below 1 Hz to about 40 Hz. Bone
Growth Stimulators, used to heal broken bones, run
at various frequencies. Deep Brain Stimulators, which
use implanted electrodes to impart electrical pulses,
run from between 120 and 160 Hz directly to the brain
to control involuntary muscular tremors in Parkinson's
disease. Heart Pacemakers use an electrical impulse
to regulate the heart's rhythm.
