Alophysio,

I can't thank you enough for helping to put things in perspective and adding a bit of data to the mix - much easier than trying to sort my way through the diagrams and charts in the user's manuals for these devices!

Initially, I thought that the device that the chiro was using was a TENS device - I did a bit of research on that, and was comfortable with it. Until I saw the manufacturer's label on the machine after my last treatment where it clearly said "interferential".

Anyway, we're flying through Sydney at the end of July on our way to Melbourne (I may be a Yank, but I'm married into a family of wonderful Australians who are already clamoring to see the baby ). I'll wave hello and more thanks when we come through!

thanks again,
