What Is TENS?

  • 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 two-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 neurochemicals occurring naturally in the brain which have analgesic properties.

Indications: 
  • TENS is indicated to be used under a physicians prescription for the symptomatic relief of chronic intractable pain.

How To Connect Grafco Analog TENS Unit?

Insert battery
Turn the device to the OFF position before inserting or removing the battery. When inserting the battery, ensure the battery polarity (+ and -) markings match the markings on the device.

Prepare the Skin
Prepare the skin as previously described and according to the instructions provided with your electrodes. Before attaching the electrodes, identify the area that your physician / clinician has recommended for electrode placement.
  1. Connect the lead wires to the electrodes: connect the lead wires to the electrodes before applying the electrodes to the skin. Warning: Ensure both Intensity Control Knobs for Channel 1 and 2 are turned to the OFF Position (counterclockwise) before applying the electrodes. 
  2. Place electrodes on the skin: 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
  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 dont 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 intensity to a comfortable level; or cease stimulation and contact your physician.

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
