I bought one from local rehab supply company. About $800, but was covered by insurance.

Make sure it can do "Russian" stimulation. Otherwise, it's just a tens unit and that is not what you need. Ask your PT to recommend a supplier.

If you want details of the one I have, let me know.

If you don't mind sharing the details of yours I would be greatly appreciative. No insurance here but I will pay. My PT didn't really have a recommendation. He suggested I asked someone who had a good outcome with the use of a specific model.

It is made by SpectraMed. It the Polaris Athlete (don't have a model number), but picture is attached. You can also see the settings that I use. These settings came from advise of by rehab doctor and me trying different settings. It is pretty small, about the size of a deck of cards, but it is powerful. Make sure you get one that has 2 channels and Russian stim capability. To get one that has high current output capability (Russian stimulation), you have to have a prescription from a doctor. Anything that says "TENS" is probably not what you want. Amazon wont sell one because of the prescription requirement. Here is a link to one that looks similar to mine Polaris TENS | Dual Channel TENS | Medi-Stim, Inc..
