Spinal Cord Stimulator Trial . The permanent spinal cord stimulator is pacemaker type of generator that is implanted under the skin above the hip and connected to leads placed into the epidural space. The electrodes on the leads stimulate the spine at a higher frequency than do incoming pain nerve signals, thereby causing the spine to filter out most of the incoming pain. However prior to implanting such expensive technology, a trial lead placement is performed for three to 1. During the trial period at home, the patient is able to adjust stimulation settings to optimize pain relief. Spinal Cord Stimulation Informed Consent Information. If this is a “Trial” stimulator placement. In addition, there are some risks that are specific to the spinal cord stimulator. Spinal cord stimulation allows you to be in control of your pain relief. If and only if the patient receives more than 7. Prior to the permanent implant, the trial leads are removed by simply pulling on them. Spinal Cord Stimulator Trial Problems In AmericaHome Care after Spinal Cord Stimulator Trial HFFY#6805. Spinal cord stimulation. A trial electrode will be put in first to see if it helps your pain. Spinal cord stimulation uses low voltage. A spinal cord stimulator. Pre-implant Patient Education Resources. Video; Brochures; Websites; Images. Find out how to evaluate the results of the screening trial for spinal cord stimulation. What are the requirements for a SCS trial? Failed all conservative therapies, oral or transdermal narcotics are not controlling the pain, and there are no other definitive surgeries or procedures that will permanently help the pain. Insurance precertification. MMPI and psychological assessment. PT assessment for suitability for an intrathecal pump. No history of substance abuse, narcotic diversion, or prescription narcotic abuse. Patient is deemed a candidate based on the personal interactions with the clinic physician and staff. No medical issues that would preclude a SCS (infection over the generator or lead placement site, able to undergo an anesthetic, etc.). Chronic constant pain that cannot be relieved completely in any position. Burning type of pain responds better than any other pain.
Trial is performed by a physcian only. What are the pain locations that are usually amenable to SCS? Leg or arm pain more than back or neck pain, pain over the back of the scalp (occipital pain), chest pain, groin pain. What pain sources are usually considered for SCS? ![]() RSD, post- spine surgery pain referring to the foot or hand, angina that cannot be adequately controlled with medications and no surgeries are possible, occipital neuralgia (back of the head), peripheral vascular disease pain. What are the risks? Bleeding, infection, nerve injury, spinal cord injury, blood clots in the spine, abscesses, spinal headaches, weakness or numbness of a leg or arm after the surgery, paralysis, need for further open emergency surgery, and meningitis are all rare. How is a SCS trial conducted? You will be brought to an operating suite in an office, surgery center, or hospital, and sometimes IV sedation is given, an epidural needle is placed into the low back under x- ray guidance. A lead with electrodes attached is then guided into the epidural space and advanced to the mid back for leg pain and to the neck for arm pain. For occipital head pain the placement is across the back of the scalp, and for angina pain the leads are placed at the level of the upper thoracic spine. Electrical stimulation through the leads is given and if the coverage area is adequate, the needles are removed, the leads taped in place, and you will be sent home. If inadequate stimulation is seen prior to removing the needles, the lead position may be adjusted. The leads usually remain in for three to 1. SCS permanent implantation is indicated.

A mild tingling sensation in the back and extremities. Too high a stimulation will result in positional shocks and too low will result in lack of pain control. The leads are floating in the epidural space during the trial period and will result in positional changes in stimulation. Therefore one should not drive with temporary trial stimulator turned on. The permanent leads have much less positional nature after a few months after implantation.
