Hello Mary,
I always look up unfamiliar treatments or solutions for pain to see what the experts say...not just physicians, but the researchers who study these things.
I had never heard of "Scenar" before, so I googled as a beginning and found many ads an promotions, but no evidence of independent testing or scientific studies. So, I dug a little further, to see if there were any clinical studies (one started but results never reported), research papers (none), reports from universities or teaching hospitals (no) or in clinical journals (no). So is the device tested or approved by the FDA No. Is there any information about the qualifications of the people selling and/or recommending the devices? No.
Do we hear about it in mainstream medicine or PT? No, and we surely would have if it was as fabulous as advertised - it has been on the market for about 30 years.

Where did you hear about it? What kind of pain are you hoping to relieve?
Sue

Hi Mary
I just joined the neuropathy support group here and found your question when I searched SCENAR. I see it’s been a couple of years but here’s my experience with SCENAR and I’m happy to answer any questions. I’d been dealing with post-surgical neuropathy for over a year and decided to do some research for something that might help. I found SCENAR and was lucky there’s a certified provider in my area. It IS FDA approved and widely use in Europe and Asia. My provider thinks it’s somewhat geopolitical that it’s not more known or used in the US because it was first developed in Russia. Anyway, after my first session, I felt the ground under my feet in a way I hadn’t since my surgery/neuropathy. I also felt more flexibility in my feet and ankles. I heard my ankle ‘crack’ for the first time since then. It’s helped dramatically with pain control after multiple sessions. It’s too bad it’s not more widely known or covered by insurance. My practitioner charges $60 per session (1 - 1&1/2 hrs). It’s electro stimulation and not painful, maybe occasionally a little sharp). It uses a million or so random signals so the brain doesn’t get used to it. It sends signals to the brain to tell the body to pay attention to certain areas and wakes up the body’s natural healing abilities.

The inventor of TENS, widely used in PT, wrote a book comparing the 2 and he concluded that SCENAR is head over heels better. It’s for all kinds of pain management.
