Graham-Field Grafco Digital TENS Unit

More Information

• Contraindications:
  - Any electrode placement which applies current to the carotid (neck) region
  - Patients with implanted electronic devices (for example, a pacemaker) or metallic implants should not undergo TENS treatment without first consulting a physician
  - Any electrode placement which causes current to flow transcerebrally (through the head)
  - The use of unit whenever pain symptoms are undiagnosed and the etiology is unknown
• What is TENS (Transcutaneous Electrical Nerve Stimulation)?
  - TENS is a treatment whereby electrical impulses are applied to nerves through electrode pads placed on the skin
  - TENS is non-invasive and does not use pharmaceuticals
• TENS uses a 2-pronged approach to pain relief:
  - First, sensory nerves are targeted, stimulating them to block pain signals and prevent their transmission to the brain
  - Second, TENS promotes the production of endorphins, eurochemicals occurring naturally in the brain which have analgesic properties
• Operating Grafco:
  1. Connect the lead wires to the electrodes before applying the electrodes to the skin. Note: Ensure both intensity controls for Channel 1 and 2 are turned to the OFF Position (counterclockwise) before applying the electrodes.
  2. Place the electrodes on the skin as recommended by your physician/clinician.
  3. Insert Lead Wire Connector into the Device: Plug end of lead wire into the channel output port (jack) to be used; push the plug in as far as it will go.
  4. Select Treatment Settings: Ensure your unit is still set to the proper settings recommended by your physician/clinician.
  5. Adjusting Channel Intensity Control: Locate the intensity control knob (Channel 1 or 2) at the top of the unit. Slowly turn the intensity control knob clockwise until the stimulation is at the level recommended by your physician/clinician. (If you do not feel anything, turn the knob OFF then ON again and carefully turn the control knob until you feel a tingling or slight twitch under or around the electrodes.) Always start with the lowest setting and increase the intensity slowly. If the stimulation levels are uncomfortable or become uncomfortable, reduce the stimulation amplitude to a comfortable level; or cease stimulation and contact your physician.
  6. Setting Patient Compliance Counter:
  • To turn counter on: While the unit is ON, hold down the UP button and press the MODE button at the same time.
  • To Reset Counter: While the unit is ON, press UP button and press the MODE button at the same time (this will take you into the compliance counter), then push the DOWN button and press MODE button at the same time.
  • Press the UP and MODE buttons at the same time to return to the treatment status.
  If the stimulation levels are uncomfortable or become uncomfortable, reduce the stimulation intensity to a comfortable level; or if problems persist, cease stimulation and contact your physician/clinician.
