Circuit for TENS or EMS

[Ed4tips]

I'm looking for a diagram for a TENS or EMS circuit. Does anyone have one or know where one is posted?

I'll bite! Just what is a TENS or EMS circuit? WHat is it used for? Give some details.

I've forgotten the exact acronym that TENS stands for(someting like Topical Electronic Nerve Stimulator?), but I've got a TENS unit and it works!.

It's basically a small battery powered unit used for pain management. You attach electrodes around the affected area - the lower back in my case - and you can "jam" the appropriate nerves responsible for pain conduction. This is done by tuning the variable frequency, variable amplitude pulse controls to find a setting that suits your particular condition.

I saw one in Elektor Electronics 'TENS ' . Search google for biomedical instrumentation I have seen plenty hobby sites employing 8051/PIC or even 555 for doing that
