You are correct that the Alpha-Stim is very similar to the TENS Unit. My husband lived on the TENS Unit before he lost his battle with Dioabetes in 1997. It literally allowed him to work 4 years longer than he otherwise would have been able to.
The Alpha-Stim has 3 different models, from what I can tell. The Alpha-Stim 100 and the Alpha_Stim SCS (Stress Control System) are both used for anxiety, depression and insomnia. The Alpha-Stim PPM (Personal Pain Manager) is designed as an alternative to the TENS Unit for localized pain.
Hopefully, this will help you for what you are looking for.
Good luck and again, it's nice to see you on the PM Forum........Sherry :)
