It's a TENS machine. It sends out electrical pulses and you can use it on your feet and it has pads to use on other places on the body

I have the Dr. Ho system. It's as good a tens unit in physio or hospital, my problem is the help it provides is short lived. Because of that I put it away and forgot about it. Think I'll dig it out again. Thanks for the reminder.

Thank you for explaining

Thanks for explaining. Never heard of it before.

Sorry never heard of it!
