Pain Management
  • For adjunctive treatment of post-traumatic pain syndromes
  • For management and symptomatic relief of chronic (long-term) intractable pain
  • As an adjunctive treatment in the management of post-surgical pain problems
Muscle Stimulation
  • Relaxation of muscle spasms
  • Prevention or retardation of disuse atrophy
  • Increasing local blood circulation
  • Muscle reeducation
  • Immediate post-surgical stimulation of calf muscle to prevent phlebothrombosis
  • Maintaining or increasing range of motion
EMS devices should only be used under medical supervision for adjunctive treatment of medical diseases and conditions.


  • Thrombophlebitis
  • Manifest thrombosis
  • Cardiac demand pacemaker
  • Acute danger of hemorrhage
  • Disturbances in cardiac rhythm
  • In tetany, caution should be exercised in dosing.
  • Acute local inflammatory processes caused by bacterial or viral infection (for example: furuncle phlegmon, herpes simplex, acute herpes zoster)
  • Do not stimulate over carotid sinus!
  • Do not stimulate transcerebally!
  • Should not be used on cancer patients.


  • Federal law restricts the sale, distribution, or use of this unit to, by, or on the lawful order of a licensed practitioner.
  • The safety of interferential current units for use during pregnancy or delivery has not been established.
  • Keep the units out of the reach of children.
  • In pain management, medical professionals using interferential current stimulators are accustomed to set intensity of the units above sensory and below motor threshold. In a few rare cases, the licensed practitioner might observe a motor contraction whereas the patient still will not report skin sensation. Therefore, in these cases the licensed practitioner should observe the contraction, and treat below motor threshold and be aware that in some cases reduced skin sensitivity might exist.
  • Avoid too strong pressure of the vacuum. Adjust the pressure at the minimum required to ensure a firm contact of the vacuum electrodes.
  • Transcutaneous electrical nerve stimulation is ineffective for pain of central origin.
  • Pay attention to contraindications, precautions and try to avoid adverse effects!
  • Transcutaneous electrical nerve stimulation is of no curative value.
  • Transcutaneous electrical nerve stimulation is a symptomatic treatment and as such it suppresses the sensation of pain.
  • Electronic monitoring equipment such as ECG monitors or ECG alarms will not operate properly when a transcutaneous electrical nerve stimulator is in use.
  • The long-term effects of chronic electrical stimulation are unknown.
  • Adequate precautions should be taken in the case of persons with suspected heart problems.
  • Adequate precautions should be taken in the case of persons with suspected or diagnosed epilepsy.
  • Caution should be used in the transthoracic application of EMS devices in that the introduction of electrical current into the heart may cause arrhythmias.
  • Precautions should be observed in the presence of the following:
    • Following recent surgical procedures when muscle contraction may disrupt the heeling process.
    • Over the menstruating uterus.
  • Some patients may experience skin irritation or hypersensitivity due to the stimulation or electrical conductive medium. The irritation can usually be reduced by use of an alternate conductive medium, or alternate electrode placement.
