Special Precautions and Contraindications

We could not find any specific precautions for the application of Aussie Current, however as this is similar to other forms of electrical stimulation the general contraindications indicated for these would also apply.  These are outlined in the APA Guidelines for the use of electrophysical agents.

Contraindications to electrical stimulation include;
  • Transthoracic applications (antero-posterior thorax, arm to arm, leg to arm).
  • Use within 3m of operating short wave diathermy equipment.
  • Pregnancy in the vicinity of the uterus.
  • Placed in the vicinity of an inbuilt stimulator or pacemaker.
  • Unreliable patient.
  • Undiagnosed pain.

Precautions should be made with;
  • Circulatory insufficiency.
  • Risk of dissemination.
  • Exacerbation of existing conditions.
  • Unable to communicate.
  • Sensory loss.
  • Avoid applications over broken skin.
  • Repeated uses of self-adhesive electrodes, electrode sponges and covers   can reduce their conductivity and necessitate higher stimulus intensities.

Electrodes

As Aussie Current is a MFAC small electrodes should not be used (Robertson et al, 2001). In the studies conducted by Ward and colleagues on wrist extensor torque conductive rubber electrodes were used measuring 44 x 40mm. The electrodes were place so as to efficiently stimulate the wrist extensors, ensuring that the cathode was the distal electrode (Ward et al, 2006).

Depending on the target muscle electrode size and placement will vary, but it is important to ensure general safety precautions are adhered to.

  1. Not sure that the cathode behaves as such in an AC field - and why distal when they are so close together anyway? Overall good blog - CY
