Spinal Cord Stimulation Trials

Overview

Spinal Cord Stimulator Trial (SCS trial) is a temporary medical device placed under your skin that sends a mild electric current to your spinal cord to block the feeling of pain. The goal of the stimulator is to help you better manage your pain and potentially decrease the amount of pain medication you need. The trial period is like a “test drive” to determine if it will help you long-term.

Spinal Cord Stimulation is commonly used to treat conditions such as failed back surgery syndrome, post-laminectomy syndrome, complex regional pain syndrome (CRPS), neuropathy, refractory lumbar radiculopathy, chronic abdominal pain, and refractory angina pectoris. Many patients with these conditions experience significant relief, often ranging from 50-100%.

It’s important to note that stimulation does not eliminate the source of pain; it simply interferes with the signal to the brain. The trial usually lasts 5-8 days, to achieve a 50-100% reduction in pain. At the end of the trial, the stimulator is removed. If the stimulation works well for you, we can discuss whether you want to have it implanted long-term. However, stimulation does not work for everyone, and if it is not effective, the implant can be removed without damaging the spinal cord or nerves.

Procedure

Healthcare provider will help position you to make sure the procedure can be completed with the least amount of discomfort for you. An IV is placed and antibiotics are given. The skin is cleansed with a sterilizing solution (chlorhexidine) and a sterile drape is placed. A local anesthetic medication typically (Lidocaine) is given to numb the skin. Next, fluoroscopy (x-ray) or ultrasound is used to find the target.

The physician will provide local anesthesia (numbing medicine) and place the needle into your epidural space. They will then place the spinal cord stimulator lead into position. This will all be done under x-ray. Once it is in the right place, the representative from the company will help program it to make sure it is in the best possible location for each patient. Once this is accomplished, the needle is removed and the lead is left in place and taped to your skin with sterile tape. You then can go home and use the device. During the entire procedure, you will be constantly monitored by our team. You will be given time after the procedure to make sure you feel good and are not having side effects before leaving the clinic.

 Risks and side effects?

The procedure is generally safe, with minimal risks and rare serious complications. We prioritize safety and take every precaution to minimize any potential issues. Risks may include but are not limited to, a vasovagal response (fainting), temporary or increased pain, infection, bleeding, permanent skin changes, allergic reactions to medications, and unintended nerve injury. Your healthcare provider will discuss these risks with you and take steps to mitigate them during the procedure.
