2 Medical background

2.1 TENS

TENS (Transcutaneous Electrical Nerve Stimulation) gives good results in acute and chronic pain conditions of many

kinds. It is clinically proven and used daily by physiotherapists, other caregivers and top athletes around the world.

High-frequency TENS activates the pain-inhibiting mechanisms of the nervous system. Electrical impulses from

electrodes, placed on the skin over or near the painful area, stimulate the nerves to block the pain signals to the

brain, and the pain is not perceived. Low-frequency TENS stimulates the release of endorphins, the body’s natural

painkillers.

TENS is a safe treatment method and has, in contrast to drugs and other pain relief methods, no side effects. It may

be sufficient as the only treatment form, but it is also a valuable complement to other pharmacological and/or physical

treatments. TENS does not always treat the cause of pain. Consult your doctor if pain persists.

2.2 NMES

NMES (NeuroMuscular Electrical Stimulation) is used successfully both in medical rehabilitation and as a

complement to athletic training on all levels.

The goal of electrical muscle stimulation is to achieve contractions or vibrations in the muscles. Normal muscular

activity is controlled by the central and peripheral nervous systems, which transmit electrical signals to the muscles.

NMES works similarly but uses an external source (the stimulator) with electrodes attached to the skin for

transmitting electrical impulses into the body. The impulses stimulate the nerves to send signals to a specifically

targeted muscle, which reacts by contracting, just as it does with normal muscular activity.

Electrical muscle stimulation is suitable for all the muscles in the body. It can be used to strengthen muscles

weakened by surgery, a fracture, etc., and improve mobility. It is also an excellent tool for stroke rehabilitation,

helping patients in handgrip and gait training.

Electrical muscle stimulation for rehabilitation purposes should be tried out individually by a physiotherapist or other

caregiver for the best results.

3 Precautionary measures

 Inspect the equipment prior to use.

 Use the stimulator only as stated in the operating instructions.

 Only Enraf-Nonius accessories should be used with the stimulator

 Never use the Tensmed P82 or S82 on patients who have sensitivity problems or are unable to let

you know if they feel any discomfort, however slight

3.1 WARNING!

Consult with physician.

o Consult with the patient’s physician before using the device, because the device may cause lethal

rhythm disturbances to the heart in susceptible individuals.

Skin condition.

o Apply stimulation only to normal, intact, clean, healthy skin.

Long term effects.

o The long-term effects of chronic electrical stimulation are unknown.

Stimulation location

o Stimulation over Neck or Mouth. Do not apply stimulation over the patient’s neck (especially the

carotid sinus) or the patient’s mouth, because this could cause severe muscle spasms resulting in

closure of the airway, difficulty in breathing, or adverse effects on heart rhythm or blood pressure.

Stimulation across Chest.

o Do not apply stimulation across the patient’s chest, because the introduction of electrical current into

the chest may cause rhythm disturbances to the patient’s heart, which could be lethal.

Across the head.

o 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.

Stimulation over compromised skin.

o Do not apply stimulation over open wounds or rashes, or over swollen, red, infected, or inflamed

areas or skin eruptions (e.g., phlebitis, thrombophlebitis, varicose veins).

Stimulation near cancerous lesions.

o Do not apply stimulation over, or in proximity to, cancerous lesions.

Stimulation over metallic implants.

o Do not apply stimulation directly over implanted metallic devices, because this may cause shock or

burns.

Stimulation over eyes.

o Do not apply stimulation directly on the eyes.

Environment

o Electronic monitoring equipment. 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.

ENGLISH

081-400-245-43_EN Page 5 of 39

Bath or Shower.

o Do not apply stimulation when the patient is in the bath or shower. Do not apply stimulation in humid

atmosphere exceeding 75% of relative humidity.

Sleeping.

o Do not apply stimulation while the patient is sleeping.

Driving or operating machinery.

o Do not apply stimulation while the patient is driving, operating machinery, or during any activity in

which electrical stimulation or involuntary muscle contraction can put the patient at risk of injury.

Electrodes for Single Patient.

o Do not share electrodes with other persons. All users should have individual set of electrodes to

prevent undesirable skin reactions or disease transmission.

Accessories.

o Use this device only with the leads, electrodes, and accessories recommended by the manufacturer.

Use of other accessories may adversely affect the performance of the device or may result in

stronger electromagnetic emissions or reduce the electromagnetic immunity of the device.

No Modification.

o No modification of the equipment is allowed.

Pregnancy.

o The safety of electrical stimulation during pregnancy has not been established.

Skin irritation.

o Some patients may experience skin irritation or hypersensitivity due to the electrical stimulation or

electrical conductive medium (gel). The irritation may be reduced by using an alternate conductive

medium or alternate electrode placement. Some patients may experience redness under the

electrodes after a session. This redness usually disappears within a few hours. Advise the patient to

consult the clinician if the skin redness does not disappear after a few hours. Do not start another

stimulation session in the same area if the redness is still visible. Don’t scratch the redness area.

Heart Disease.

o Patients with suspected or diagnosed heart disease should follow precautions recommended by their

physicians.

Epilepsy.

o Patients with suspected or diagnosed epilepsy should follow precautions recommended by their

physicians.

Internal Bleeding.

o Use caution when the patient has a tendency to bleed internally, such as following an injury or

fracture.

After Surgery.

o Use caution following recent surgical procedures when stimulation may disrupt the patient’s healing

process.

Over uterus.

o Do not place electrodes directly over the uterus or connect pairs of electrodes across the abdomen if

you are pregnant. The reason is that, theoretically, the current could affect the foetus’s heart

(although there are no reports of it being harmful).

Lack of sensation.

o Use caution if stimulation is applied over areas of skin that lack normal sensation. Don’t apply

stimulation on patient unable to express themselves.

Stimulation.

o The stimulator should only be used with skin electrodes intended for nerve and muscle stimulation.

Muscle soreness may occur after stimulation but usually disappears within a week.

Hot casing or batteries.

ENGLISH

081-400-245-43_EN Page 6 of 39

o Under extreme use conditions, some parts of the casing might reach up to 109 °F (43 °C). Use

caution when manipulating the batteries right after device use or when holding the device. There is

no particular health risk associated with this temperature besides your comfort.

Children.

o Keep this device out of the reach of children.

Electrode Size.

o Do not use electrodes with an active area less than 16 cm2, as there will be a risk of suffering a burn

injury. Caution should always be exercised with current densities more than 2mA/cm2.

Strangulation.

o Do not wrap leadwires around your neck, and keep them out of the reach of children. Strangulation

may result from entanglement in the leadwires.

Tripping.

o Care should be used to avoid tripping on lead wires

 .

Damaged Device or Accessories.

o Never use the device or any of its accessories if it is damaged (case, cables, etc.) or if the battery

compartment is open as there is a risk of electric shock. Carefully inspect the lead wires and

connectors prior to each use.

Inspect Electrodes.

o Inspect electrodes before each use. Replace electrodes when they begin to deteriorate or lose

adhesion. Poor contact between the electrodes and the patient’s skin increases the risk of skin

irritation or burns. Electrodes will last longer if used and stored according to instructions on electrode

packaging. Attach the electrodes in such a way that their entire surface is in contact with the skin.

Heat and Cold products.

o The use of heat or cold producing devices (e.g. electric heating blankets, heating pads or ice packs)

may impair performance of the electrode or alter the patient’s circulation/sensitivity and increase the

risk of injury to the patient.

Pulled muscles.

o Do not apply electrodes over pulled muscles. Using the stimulator on a previously extended muscle

might further pull such muscle. The higher the stimulation intensity, the higher the risk to further

overextends such muscle.

3.2 CAUTIONS

Electrosurgical equipment or defibrillators.

o Disconnect the stimulation electrodes before using electrosurgical equipment or defibrillators.

Otherwise skin burns may be caused below the electrodes and the device might be destroyed.

Magnetic Resonance Imaging.

o Do not wear electrode or the device during Magnetic Resonance Imaging (MRI) scans as this may

result in metal overheating and causing skin burns in the area of the electrode.

Flammable or explosive environment.

o Do not use the device in areas where there is a risk of fire or explosion, such as oxygen-rich

environments, in the vicinity of flammable anaesthetics, etc.

Power supply.

o Never connect stimulation cables to an external power supply as there is a risk of electric shock.

Near other equipment.

o Do not use the device beside or stacked on top of any other equipment. If you must use it side by

side or on top of another system, you should check that the device works properly in the chosen

configuration.

Supervision.

o Use this device only under the continued supervision of a licensed practitioner. Electrode placement

and stimulation settings should be based on the guidance of the prescribing practitioner.

ENGLISH

081-400-245-43_EN Page 7 of 39

Manufacturer.

o The manufacturer does not take any responsibility for any electrode placements other than

recommended.

Foreign bodies.

o Do not allow any foreign bodies (soil, water, metal, etc.) to penetrate the device and the battery

compartment.

Batteries.

o Do not carry batteries in a pocket, purse, or any other place where the terminals could become short-

circuited (e.g. by way of paper clip). Intense heat could be generated and injury may result. Never

open the battery cover during stimulation in order to avoid electrical shock. Remove the batteries

from the device if you do not intend to use it for a prolonged period of time (more than 3 months).

Extended storage of the batteries in the device might lead to batteries and device damage.

Cable.

o The cable is best preserved if left attached to the stimulator between sessions. Do not jerk the cable

or connection.

Additional Precautions for TENS

TENS is not effective for pain of central origin, including headache.

TENS is not a substitute for pain medications and other pain management therapies.

TENS devices have no curative value.

TENS is a symptomatic treatment and, as such, suppresses the sensation of pain that would otherwise serve

as a protective mechanism.

Effectiveness of TENS is highly dependent upon patient selection by a practitioner qualified in the

management of pain patients

3.3 DANGER

Electrodes.

Any Electrode with a minimum active area of 16 cm² may be used with this device. Use of an electrode with an

area less than 16 cm² can cause burns when the unit is used at higher intensities. Consult your clinician prior

to using any electrode less than 16 cm².

•

Dangerous voltage.

Stimulus delivered by the waveforms of the device, in certain configurations, will deliver a charge of up to 20

microcoulombs (µC) or greater per pulse and may be sufficient to cause electrocution. Electrical current of this

magnitude must not flow through the thorax because it may cause a cardiac arrhythmia

3.4 ADVERSE REACTIONS

Patients may experience skin irritation and burns beneath the stimulation electrodes applied to the skin.

• Patients may experience headache and other painful sensations during or following the application of

electrical stimulation near the eyes and to the head and face.

Patients should stop using the device and should consult with their physicians if they experience adverse

reactions from the device.

•Do not disconnect any stimulation cables during a session while the stimulator is switched on. Switch the

stimulator off first. Always turn off the stimulator before moving or removing any electrodes during a session.

• •Do not use electrodes with an active area less than 16 cm2, as there will be a risk of suffering a burn injury.

Caution should always be exercised with current densities more than 2mA/cm2.

ENGLISH

081-400-245-43_EN Page 8 of 39

•Do not apply stimulation in the vicinity of metal. Remove jewelry, body piercings, buckles or any other

removable metallic product or device in the area of stimulation. Never use the electrodes contra-laterally, i.e.

do not use two pins connected to the same channel on opposite segments of the body.

Never carry out an initial stimulation session on a person who is standing. The first five minutes of stimulation

must always be performed on a person who is sitting or lying down. In rare instances, people of a nervous

disposition may experience a vasovagal reaction. This reaction is connected with fear of the muscle

stimulation as well as surprise at seeing one of their muscles contract without having intentionally contracted

it themselves. A vasovagal reaction causes heart to slow down and blood pressure to drop, which can make

you feel weak and faint. If this does occur, stop the stimulation and lie down with the legs raised until the

feeling of weakness disappears (5 to 10 minutes).

Sudden temperature changes can cause condensation to build up inside the stimulator. To prevent this,

allow it to reach room temperature before use

The stimulator turns off after 5 minutes of inactivity to spare batteries.

8.2 SPECIAL INSTRUCTIONS

Mixed frequency stimulation (P4)

Mixed frequency stimulation is a combination of high (80 Hz) and low (2 Hz) frequency stimulation with separate

amplitude settings.

1. First set the amplitude for 80 Hz stimulation when the upper part of the high/low frequency

symbol is flashing

2. When the bottom part of the symbol flashes for the first time, the amplitude for 2 Hz stimulation

will start at the same level as is set for 80 Hz. Adjust the amplitude until you get visible muscle

contractions.

The period between the frequency changes is preset to 3 seconds.

See chapter FREQUENTLY ASKED QUESTIONS for further information on mixed frequency

stimulation

ENGLISH

081-400-245-43_EN Page 13 of 39

Intermittent stimulation + hand switch (P6–P19 and P26-P28)

Programs P6–P19 and P26-P28 are intermittent stimulation programs with rest time between the muscle contractions

(work time), see figure.

The contraction gradually increases during ramp-up time and reaches maximum contraction during work time. During

ramp-down time, the stimulation gradually decreases until the rest time starts. The rest time can be without or with

stimulation (Active Rest).

In intermittent stimulation programs the work/rest symbol is shown on the display. The upper part of the symbol is

flashing during work time and the bottom part during rest time.

Programs P6–P19 and P26-P28 can be used together with the hand switch to manually control the duration of the

work time and rest time. Press the hand switch button during rest time for ramp-up time and contraction. The duration

of the work time is preset but can be shortened by pressing the hand switch button. The rest time lasts until the hand

switch button is pressed again.

See chapter FREQUENTLY ASKED QUESTIONS for further information on using the hand switch.

Intermittent stimulation with Active Rest (P16- P17)

In programs with Active Rest, the stimulation is active also during the rest time, which means that you have to

perform two amplitude settings for each channel.

Amplitude setting for contractions (work time):

When the upper part of the work/rest symbol is flashing, increase the amplitude gradually until you get muscle

contractions without pain.

Amplitude setting for Active Rest: When the bottom part of the work/rest symbol is flashing, increase the

amplitude gradually until you get muscle vibrations.

See chapter FREQUENTLY ASKED QUESTIONS for further information on Active Rest.

10.2 PRESET PROGRAMS – NMES

The TensMed S82 offers additional to the 5 TENS programs 23 NMES programs, adjusted to either smaller or larger

muscle groups. The pulse duration is 200 µs when stimulating smaller muscle groups and 300–400 µs when

stimulating larger muscle groups.

Two programs can have the same headline. The difference between them is for instance the length of the work time

and the rest time and/or the frequency. Have your patient’s status in mind when choosing programs. If the patient’s

muscular capability is assessed the correct program is easier to find. A longer rest time is recommended when

stimulating a weaker muscle since the muscle is then given a longer preparation time before the next contraction.

The use of a hand switch will individualize the treatment even more.
