I trialled with perc leads. Actually, my original stim trial only used a single lead.
My stim is for CRPS, which I think you know from the other discussion? When I had mine implanted, it was only my right leg affected and the doctor decided only to put in a single lead (also, unfortunately, a battery unit that could only accomodate a single lead).
I'd changed doctors after that one more or less dumped me in the 'too hard basket' - partly because I've also got quite bad dystonia/contracture complications and I needed someone who knew how to manage them, partly because I just couldn't get in touch with him when I needed him. about 18 months after my stim was implanted, the CRPS started spreading to my left leg. Sympathetic blocks didn't work, I had a bad reaction to ketamine because I was having some trouble with my heart and when he suggested replacing the battery and putting in a second lead to cover my left leg, I was quite keen.
I had great coverage for a few days but I also have stomach issues and vomit a lot - and the vomiting shifted the lead right out of place. We gave my back a few months to settle down, then he went back in about three months later and replaced the lead- still a perc at this stage. That was in late 2008. Because of my stomach problems, I lost an enormous amount of weight - I ended up in hospital in late '09 weighing less than 60lb - and because of that everything shifted again and the newer lead came out of place. It was causing me a lot of pain even with the stim turned off because it was irritating all the surrounding tissues, but I just wasn't well enough to justify elective surgery.
When I started discussing it with my technician, it was him who told me about this new lead type - he felt it might be better for me given I'd had so much trouble getting the traditional perc to stay in place. We'd also had a lot of trouble getting solid coverage - I'd get a patch here, a patch there, and he hoped that I'd have something more uniform with this new sort. Right on too - Like I said, I can't use it at the moment until we sort out what is going on with my compression fractures, but now that he's got a good program for me it's like wearing a pair of stockings that give a very gentle, rolling massage :)
