The SCE are the initials for Spinal Cord Stimulator. It generates a pulse to block the pain that travels from the affected area to the brain. Not everyone receives 100%. I did quite a bit of research before I received one. In the research, it reported that most folks receive between 50-80% pain relief.
If you google Abbott Laboratories you will find a video showing the SCS procedure. The stimulator that I have has a battery that does not require charging and it lasts for 10 years. I received it at 78 and I don't think that I will be around at 88 or who know. I did not want to have to charge the SCS every night like many of the others out there, require.
I had one MRI done for the Lumbar and the second was done for the Cervix.
I hope that I have adequately answered your questions. If you would like to chat on the telephone, my number is 805-551-8734 and I am in the Pacific time zone. God bless you. Charles
