I have the Boston Scientific spinal cord stimulator. First, you have to have a trial one for 7 days and nine worked awesome. Just had the permanent one 6 weeks ago and still to early but getting up and down and sleeping has improved 100%. The walking and standing so good yet but have been told it could take months, I'm hopeful! At least I am not screaming out with pain. Research. Before surgery I used a Tens unit.
