1. Contiguous Placement This form of electrode placement is the most common method used It involves placing the red lead proximal alongside the spine where the dermatome on which your pain lies enters and exists The black lead distal is normally placed over or near to the pain site Your Physiotherapist or Doctor may direct the current to cross through the pain area or using the bracket system allow the current to flow on either side of the pain site through the nerve branches that supply the pain location Acupuncture Points The placement of the red and black electrodes on the skin forms the electrical circuit for TENS It is the skin itself that creates the highest electrical resistance to stimulation The Physiotherapist or Doctor may consider using acupuncture loci which offer much lower resistance properties as a more effective site for placing the electrodes Accurately locating an acupuncture point can be difficult please seek advice from your Doctor or Physiotherapist 12 x NeuroTrac TENS Operation Manual Electrodes Types and Tips Self Adhesive reusable long term electrodes have a typical life span if looked after of 4 6 weeks We recommend cleaning the skin before placing the electrodes After use place the electrodes back onto the plastic film and in the zip tag plastic pouch Store in a cool environment Skin Electrode Types Available CODE DESCRIPTION VS 4040 40 x 40 mm square max 532.
