IDN recommends using the ES 130. There are other estim units that will work for dry needling. This unit is one that we know works well and is used at all the IDN courses. Below is a link to the ES 130 Unit.
I was wondering if you could let me know how to document the parameters when using the ES130. I am not sure what the numbers on the intensity and frequency (1-10) correspond to in Volts and Hertz. Thanks!
