Portable Electrotherapy Units
There are different types of Portable Electrotherapy units. They all have different functions for healing and
pain. Many overlap in their therapies. Check with your doctor to see
which electrotherapy unit is best for you.

Portable TENS machines stimulate sensory nerves to block
pain signals, stimulate endorphin production to help normalize sympathetic
function. TENS units are used primarily for pain relief, not
TENS devices use a two-pronged approach to pain
relief. First, they target your sensory nerves, stimulating them to block
pain signals and prevent their transmission to the brain. Second, TENS
promotes production of endorphins, the body’s natural pain reducing

EMS (or NMS) differs from TENS in that it is designed
to stimulate muscle motor nerves, while TENS is designed to stimulate
sensory nerve endings to help decrease pain.
This type of stimulation is characterized
by a low volt stimulation targeted to stimulate motor nerves to cause a
muscle contraction. Contraction and relaxation of muscles has been found to
effectively treat a variety of
conditions. An injured muscle usually experiences little
if any movement. NMS therapy remedies this by using low-voltages to
stimulate motor nerves to cause involuntary muscular contractions.
Like exercise, NMS helps to strengthen the injured area
and has been found to effectively treat a variety of problems. Most common uses: Prevent or retard disuse
atrophy, strengthening programs, reeducate muscles, post-op orthopedic
surgery, joint replacement, gait training, shoulder subluxation and
reduction of muscle spasms.

Interferential therapy is characterized
by the crossing of two electrical medium, independent frequencies that
effectively stimulate muscle fibers. These
frequencies interfere with the transmission of pain messages at the spinal
cord level and help block their transmission to your brain.
Obviously, the fewer pain messages that make it through, the less it
This deep tissue penetration can be
adjusted to stimulate nerve fibers for increased blood
flow. Interferential pain control differs from TENS because it allows a
deeper penetration of the tissue with more comfort and
increased circulation, thereby offering the patient not only pain relief
but also a degree of healing.
Common uses: Pre and post-orthopedic
surgery, joint injury syndrome, cumulative trauma disorders, increasing
circulation and pain control.

Microcurrent therapy is thought to mimic the
body’s own electrical system. It uses subtle current to build upon
naturally occurring impulses to decrease pain. Microcurrent devices take
what you already have and make it stronger, amplifying your ability to
Where TENS is used to
hide pain, Microcurrent electrical therapy, because of it is close to our own body’s
current, is thought to work on a more cellular level. It is believed that healthy tissue is the result of the direct flow of
electrical current throughout the body. Electrical balance is disrupted
when the body is injured at a particular site, causing the electrical
current to change course. The use of Microcurrent therapy is
thought to realign this flow, and help in tissue repair.

Iontophoresis or ElectroMotive Drug Administration (EMDA)
is a very effective method of delivering drugs to the affected site.
Iontophoresis is defined as the topical introduction of ionized drugs into the
skin using direct current. It is non-invasive, painless and it eliminates
potential side effects and adverse reactions which can occur with medications
delivered orally or by injection.
We carry the Ionto Plus products because we
feel that it is the quality that we want to offer our customers.
stimulation uses high voltage direct current therapy and is
most useful in acute injuries associated with major tissue trauma with
bleeding or swelling.
In contrast to TENS and Interferential units, which apply
alternating current, galvanic stimulators apply direct current.
Injured tissues are often surrounded by an
excess of fluid, which prevents nutrient- and oxygen-rich blood from
reaching them. Pulsed direct current devices remove excess fluid and
increase blood flow to the injured site to encourage rehabilitation.
pulsed galvanic stimulation (HVPGS) is gaining widespread use for wound
healing, edema reduction and pain relief Carpal Tunnel Syndrome and
Diabetic Foot are two major areas of use.
