Mine is similar and it works. I also have 2 st. Jude stimulators. They have 20 electrode paddles which is awesome. It's been 2 weeks today for me and I'm finally in bed, but still hard to get comfy. Anyway, my cervical stim paddle covers C1-4 and I get great coverage for both arms. Anyway, I hope everything goes great for you. st. Jude reps are amazing.
