I personally found the trial misleading for 2 reasons. But yes the trial gave good relief in the calves of my legs, which were feeling very heavy...due Stenosis I believe. It didnt give much back relief but walking was much easier.
I didn't think the allotted time , not even 4 full days was sufficient for an accurate assessment and also its a bit hard to judge due the uncomfortableness of the procedure.
Because the trial " hardware" was so minimal I was lulled into a false sense that the procedure was not overly invasive. The first inkling I had was just before being put 'out' my Dr said ' be prepared, you are going to be pretty sore when you wake up' ...right then I wanted out....I felt my Dr hadn't been honest with me...but I went into it with a positive attitude .
I think pain makes us desperate but its so wrong Drs minimize this procedure, that's my concern. Gd luck to us all !!

yes the trial went perfect but not so much with the permanent one. My original pain doctor who did the trial could not do my permanent because he was not available, so this other surgeon did it. I questioned them about this surgeon and they said he performed a lot of them
