ReActiv8 Restorative Nurostimulation

After 3 1/2 years trying to determine why I get bent over at the waist after approximately a half hour on my feet it has gotten worse I’ve had several diagnosis but nothing concrete. New MRIs from last week with x-rays now I’m told The deep muscle group in my lumbar region are week and, that is the cause. 3 1/2 years ago I fell on my bottom after a big dog was playing and jumped up on me, after approximately two weeks this weakness began but has become more severe. It was thought that I had some spinal stenosis but now the pain specialist says that’s not an option. He wants me to get the “ ReActiv8 Life” restorative Nurostimulation device implanted. The information I received appeared to be this was used to ease or eliminate pain in the Low back. I have very little pain mine is mainly weakness and only causes pain if I remain on my feet for longer than I probably should. Any information positive or negative would be appreciated thank you
