1 | Introduction of TENS
1. Theory of therapy
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive technique in which a low-voltage electrical current is delivered through wires
from a small power unit to electrodes located on the skin. Electrodes are
temporarily attached with paste in various patterns, depending on the specic condition and treatment goals. TENS is often used to treat pain, as an
alternative or addition to pain medications. Therapy sessions may last from
minutes to hours. The use of electrical stimulus for pain relief was popularized in the 19th centur y and became wide spread in the 1960s and 1970s using
battery power.
Transcutaneous electrical nerve stimulation (TENS) was rst introduced into
current clinical practice following Melzack and Wall‘s gate control theory of
pain in 1965. Davis (1993) and Lewith (1984) explain the gate control theory
of pain as follows. An area of the dorsal horn of the spinal cord, known as
the substantia gelatinosa, acts as a gate to nociceptive impulses. It receives
myelinated nerve bres , the largest being A bres, and small non-myelinated nerve bres (C bres). If pain impulses pass along ne myelinated bres
and C bres rather than along A bres, the gate is opened, and the patient
perceives pain. If A bre transmission of impulses is greater, the gate may
be closed.
There is also evidence that the TENS machine enhances the production of
the body‘s own natural pain killing substances: endorphins and encephalins.
Human body produces endorphins and encephalins, which are opiate-like
substances to counter the pain. Low frequency stimulation causes the release of the endorphins and encephalins.
2. Why consider digital pain relief?
Pain is a warning signal -we need these signals to tell us that something may
be wrong with our body. Without it, we may do not know that part of our body
might be damaged, thereby damaging them further. However, once we have
identied damage, pain serves little purpose. In the case of chronic, regular
pain it can signicantly interfere with daily activities and the quality of life.

3. How does the Digital Pain Relief (TENS) work?
Digital Pain Relief (TENS) works by passing harmless electrical signals into the
body from its pads. This relieves pain in two ways:
19
1. It blocks the body‘s pain signals. These are normally transmitted from the
area of damage through the nerve bers to the brain, TENS interrupts these
pain signals.
2. TENS stimulates the body‘s production of endorphins-its own natural
painkillers.

4 | Product description
The AD-2011 is a battery operated pulse generator that sends electrical impulses through electrodes to the body and reaches the underlying nerves
and muscle.
• The device is provided with one controllable output channel.
• An electrode pair can be connected to the output channel.
The electronics of the AD-2011 Digital create electrical impulses whose
Intensity, Pulse Width, Pulse Rate may be altered according to the program.
Press buttons are very easy to use and the panel cover prevents changes in
the setting.
The AD-2011 corresponds to the below standards:
• IEC 60601-1: 2005/EN 60601-1:2006/AC:2010
(Medical el ectrical equipment -- Part 1: General requirements for basic safety
and essential performance).
• IEC60601-1-2:2007/EN 60601-1-2:2007/AC:2010
(Medical electrical equipment -- Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests).

5 | Important safety hints
Retain the manual for
further use and forward
it to other users!
• Read all of the information in the operation guide and
any other literature in the box before operating the
unit.
• If there is any uncomfortable during using the device, please please stop
using it immediately and consult your doctor
• Turn o the power rst before alternate the electrode pad to the other channel
22
• Do not make sharp kinks in the connecting leads or electrodes.
• Do not use the device if you are connected to, or in the vicinity of,
high-frequency surgical or industrial equipment. This may cause burn
injuries on the skin under the electrodes, as well as problems with the
stimulator.
• Observe caution when using the device in the immediate vicinity of cellular
phones that are switched on.
• This device is not intended to be used unsupervised by children, individuals
with sensory deprivation of any kind or mentally challenged individuals. Any
users falling into these categories should be assisted by a responsible adult.
• Please don‘t use it in the bathroom or other place with high humidity.
• Please do not use it when driving, otherwise, it may lead to incident.
• Please do not use the device while in sleep.
• In the process of stimulating and therapy, please do not allow metal
parts of belts, wristwatches or necklaces touch the leaf electrode pads.
• Please don‘t use it for purposes other than outlined in this manual.
• The device might not meet its performance specications or may cause
safety hazard if stored or used outside the specied temperature and
humidity ranges in specications.
• Pregnant women should not use the device during the rst trimester, and
should always consult a doctor, midwife or physiotherapist prior to use.
• Simultaneous connection of a PATIENT to a h.f. surgical EQUIPMENT may
result in burns at the site of the STIMULATOR electrodes and possible
damage to the STIMULATOR.
• Operation in close proximity (e.g. 1 m) to a shortwave or microwave therapy
equipment may produce instability in the device output.
• Application of electrodes near the thorax may increase the risk of cardiac
brillation.
• Please do not knock down, repair, and rebuild the device privately.
• Please do not use electrode pads other than those supplied by the
manufacturer, otherwise it may bring biocompatible hazard and might
result in measurement error.
• Please do not share the electrode pads with infective persons to avoid
cross-infection.
• The output wave parameters are not be inuence by load resistance, except
output voltage. When the value of load resistance increased, the output
voltage will increase.
• Avoid strong magnetism interference, such as mobile telephone, microwave
oven, etc.
