They can work very well in the properly selected patient, who has failed most other conservative measures and doesn't have any psychosocial or secondary gain issues. A trial is done first to make sure it helps before implanting one.

The stimulator is placed in the epidural space and it sends an electrical impulse into the back portion of the spinal cord. This is where pain signals are transmitted to the brain. This stimulation then changes the signal (neuromodulation) and the new impulse the brain receives results in a new sensation (numb/tingling) being felt where the pain normally is.

In general, most physicians will perform a trial implant of the spinal cord stimulator. This allows the patient to see how much pain relief they can achieve. A trial is successful if the patient achieves 50% pain relief or greater. This criterion is different regionally. Some docs want to see a higher percentage at trial. Most folks get 40-60% relief. I have seen patients who report 100%.
