I have the Abbott SCS for about 7 mos. now, and have had minimal results. I did have the trial for about 10 days and saw some improvement,but during the trial they tell you not to bend over, or lift any objects over 5 pounds. so, it's kind of hard to see the full affect. Anyway, I now have the permanent one and see some minimal relief. I had two back surgeries, one was a laminectomy, and then 13 yrs ago a spinal fusion,, with the rods and pins put in. I have had back pain and have two dropped feet since then. I get around fine but the back pain is still there. I will say the Abbott company rep. has been great. He has met with me many times to try to readjust the implant. I have now 5 different programs on the phone app and have tried them all. So, I'd say if you get the trial, try to make sure you have it for as long as you can, and give it a good try. The only complaint I have about the device is that they tell you it only need charging every 2 or 3 months,, WRONG.. It all depends on the strength settings and to get any relief you have to have the settings set higher. So, then I have to recharge about every 3 weeks.. Not a big deal,,just a pain.. Also, they a have non chargeable one ,but it only last a few years and then you have to go thru the surgery again to put a new one in.. Not really an option for me.
Anyway, I'd recommend giving it a try as most say it gives some relief.
