How to Minimize Impedance in Electrical Stimulation

Electrical stimulation is a therapeutic modality used by health care professionals to decrease pain and increase blood flow to a particular area of the body. Units are also available for home use. Current is delivered through adhesive pads to the underlying nerves. To prevent burning the skin and to provide maximum benefit, several steps should be followed to decrease impedance -- or resistance -- under these electrode pads.

Instructions

• 1

  Use an alcohol wipe to remove oil and clean the skin where the electrodes will be placed. Allow the area to dry.

• 2

  Shave the area, if excessive hair is preventing direct contact between the electrode and the skin.

• 3

  Inspect the electrodes to make sure the entire surface is sticky. Burns can occur if current is delivered unevenly. Apply one or two drops of water to the back of the electrode to improve adhesion.

• 4

  Place the electrodes on the flattest area possible, to ensure even contact with all surfaces. For body parts that are not flat, wrap elastic material around the electrode once it is in place, to maintain contact.
