When A Negative Is a Positive – Achieving Pain Relief With A Tens Or Interferential Unit

Tens items are essentially the most used modality outdoors a ache clinic for ache aid, interferential for many used contained in the clinic, nevertheless each modalities function on comparable ache aid principals. That overriding precept is the usage of constructive or damaging costs for ache aid.

Right here is an choice for anybody with a tens unit or Infrex mixture tens / interdependent unit to achieve extra ache aid by reversing the polarity, fancy solution to say, altering the cost from damaging to constructive or vice versa. Our physique responds in a different way to damaging and constructive costs. For example say one has a bulging disc between two vertebras and the compression is on the nerve. The stress on the nerve root is the causative agent that makes the affected person expertise ache. The irritation / swelling of the disc must subside earlier than there may be considerable ache aid.

Right here is the tip that can assist any tens or interverntial affected person or clinician achieve a bonus over ache, particularly when it considerations "carryover ache aid".

As soon as the electrodes are positioned in essentially the most environment friendly place place the flip off unit off. Now take away the cable from each electrodes and reverse the cables into the alternative electrode. That is referred to as "polar reversal" and actually is altering the costs from constructive to damaging or vice versa. What most sufferers will discover is:

2. If swelling, edema are causative of the ache, the damaging cost might assist cut back the spelling and so take away a few of the structural features that’s inflicting the ache to happen.
