Spinal Cord Stimulator

Here’s an overview of how a spinal cord stimulator implant typically works:

1. Trial Period: Before undergoing the permanent implantation of a spinal cord stimulator, patients usually undergo a trial period. During this trial, temporary leads (thin wires) with electrodes at the tips are inserted through a needle into the epidural space near the spinal cord. These leads are connected to an external stimulator device that the patient wears outside the body. The patient then evaluates the effectiveness of the spinal cord stimulation in managing their pain over a period of several days to weeks.

2. Permanent Implantation: If the trial period is successful and provides adequate pain relief, the patient may be considered for permanent implantation of the spinal cord stimulator. This involves a surgical procedure in which one or more permanent leads are placed in the epidural space near the spinal cord, typically in the thoracic or lumbar region of the spine. The leads are then connected to a small implanted pulse generator (IPG) or battery pack, which is usually implanted under the skin in the abdomen or buttock area.

3. Programming: After the permanent implantation, the spinal cord stimulator is programmed by a healthcare provider to deliver electrical impulses at specific frequencies, amplitudes, and durations tailored to the individual patient’s needs. The programming can be adjusted as needed to optimize pain relief and minimize side effects.

4. Activation: Once the device is programmed, it is activated, and the patient can control the stimulation settings using an external programmer device provided by the manufacturer. Patients can adjust the stimulation intensity and settings to achieve optimal pain relief and comfort.
