EMS CONTRAINDICATIONS
Powered muscle stimulators should not be used on people with cardiac demand pacemakers.
WARNINGS
• The long-term effects of chronic electrical stimulation are unknown.
• Stimulation should not be applied over the carotid sinus nerves, particularly in people with a known sensitivity to the
carotid sinus refl ex.
• Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may
occur and the contractions may be strong enough to close the airway or cause diffi culty in breathing.
• Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause
cardiac arrhythmias.
• Stimulation should not be applied transcerebrally.
• Stimulation should not be applied over swollen, infected, or infl amed areas or skin eruptions, e.g., phlebitis,
thrombophlebitis, varicose veins, etc.
• Stimulation should not be applied over, or in proximity to, cancerous lesions.
PRECAUTIONS
• Safety of powered muscle stimulators for use during pregnancy has not been established.
• Caution should be used for people with suspected or diagnosed heart problems.
• Caution should be used for people with suspected or diagnosed epilepsy.
• Caution should be used in the presence of the following:
• When there is a tendency to hemorrhage following acute trauma or fracture.
• Following recent surgical procedures when muscle contraction may disrupt the healing process.
• Over the menstruating or pregnant uterus.
• Over areas of the skin which lack normal sensation.
• Some people may experience skin irritation or hypersensitivity due to electrical stimulation or electrical conductive
medium. The irritation can usually be reduced by using an alternate conductive medium, or alternate pad placement.
• Electrode placement and stimulation settings should be based on the guidance of the prescribing practitioner.
• Powered muscle stimulators should be kept out of the reach of children.

• Powered muscle stimulators should only be used with the leads and electrodes provided for use by the manufacturer.
• Do not apply stimulation while driving, operating machinery, or during any activity in which electrical stimulation can put
you at risk of injury.
• Muscle contractions may put the user at undue risk of injury which may include use while driving, operating
machinery, or during any activity in which involuntary muscle contractions may put the user at undue risk of injury.
ADVERSE REACTIONS
Skin irritation and burns beneath the electrodes have been reported with the use of powered muscle stimulators.
TENS CONTRAINDICATIONS
• TENS should not be used if you have a cardiac pacemaker, implanted defi brillator, or other implanted metallic electronic
device. Such use could cause electric shock, burns, electrical interference, or death.
WARNINGS
• If you are in the care of a physician consult with your physician before using this device.
• If you have had medical or physical treatment for your pain, consult with your physician before using this device.
• If your pain does not improve, becomes more than mild, or continues for more than fi ve days, stop using the device and
consult with your physician.
• Do not apply stimulation over your neck because this could cause severe muscle spasms resulting in closure of your
airway, diffi culty in breathing, or adverse effects on heart rhythm or blood pressure.
• Do not apply stimulation across your chest because the introduction of electrical current into the chest may cause rhythm
disturbances to your heart, which could be lethal.
• Do not apply stimulation over open wounds or rashes, or over swollen, red, infected, or infl amed areas or skin eruptions
(e.g. phlebitis, thrombophlebitis, varicose veins).
• Do not apply stimulation over, or in proximity to, cancerous lesions.
• 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.
• Do not apply stimulation when in the bath or shower.

• Do not apply stimulation while sleeping.
• Do not apply stimulation while driving, operating machinery, or during any activity in which electrical stimulation can put
you at risk of injury.
• Do not use the device on children, if it has not been evaluated for pediatric use.
We also recommend the following:
• Consult with your physician before using this device, because the device may cause lethal rhythm disturbances to the
heart in susceptible individuals.
• Apply stimulation only to normal, intact, clean, healthy skin.
PRECAUTIONS
• 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 is highly dependent upon the individual using. Results may vary.
• The long-term effects of electrical stimulation are unknown.
• Since the effects of stimulation of the brain are unknown, stimulation should not be applied across your head, and
electrodes should not be placed on opposite sides of your head.
• The safety of electrical stimulation during pregnancy has not been established.
• You may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical conductive medium
(gel).
• If you have suspected or diagnosed heart disease, you should follow precautions recommended by your physician.
• If you have suspected or diagnosed epilepsy, you should follow precautions recommended by your physician.

We also recommend the following:
• Use caution if you have a tendency to bleed internally, such as following an injury or fracture. Consult with your physician
prior to using the device after a recent surgical procedure, because stimulation may disrupt the healing process.
• Use caution if stimulation is applied over the menstruating or pregnant uterus.
• Use caution if stimulation is applied over areas of skin that lack normal sensation.
• Keep this device out of the reach of children.
• Use this device only with the leads, electrodes, and accessories recommended by the manufacturer to avoid adverse
reactions.
• Electrode pads are intended for single person use only.
Please be aware of adverse reactions and precautions below:
• You may experience skin irritation and burns beneath the stimulation electrodes applied to your skin.
• You may experience headaches and other painful sensations during or following the application of electric stimulation
near your eyes and to your head and face.
• You should stop using the device and should consult with your physician if you experience adverse reactions from the
device.
