If necessary, general anesthesia can be used. Paresthesia testing can still be complete despite the anesthesia. The technique of installation is relatively comparable from one type of stimulator to another. When surgical leads are placed, it is typically done with spinal anesthesia using bupivacaine. Alternatively, older model safety should be reviewed before getting an MRI. Non-rechargeable batteries have a shorter battery life compared to rechargeable, four to seven years, and ten years respectively. Most of the current spinal cord stimulator generators are MRI compatible. Chargeable stimulators charge through the patient's skin. However, more studies need to be determined by their efficacy. Spinal cord stimulators can be either chargeable or non-rechargeable. There are also stimulators being developed that are wireless. This type of stimulator is persistently adjusting settings based on neural input. Closed-loop evoked action potential stimulation is a type of stimulator that uses an algorithm to determine the frequency and pulse amplitude. There are persistently activated stimulators, high frequency, and burst stimulators. Electrical impulse control determines either persistent or tonic delivery.

Stimulators that are paraesthesia based or paraesthesia free are the two main types of stimulators. Thus stimulators affect pain by both peripheral and central mechanisms. The implant has been shown to be effective in reducing pain through the descending inhibitory pathways as well. These are known as dynamic range neurons. A spinal cord stimulator suppresses neurons within the dorsal horn of the spinal cord. When this pathway becomes disrupted as in the case of chronic pain, it is said to be dysregulated. Spinal cord stimulators function by neuromodulating the spinothalamic tract within the spinal cord. Stimulator leads can be implanted within the level of cervical, thoracic, lumbar vertebra, and the sacrum. Electrical signals, either persistent our pulsatile, are applied to the epidural space once the spinal cord stimulator is installed.

The epidural space is at its fullest at the L2 vertebra it starts superiorly with the base of the skull at the foramen magnum, then descends inferiorly until the sacrum at the sacral hiatus. Nerve roots are bathed with cerebrospinal fluid lie within the sac. The epidural space anatomically lies within the dural sac. Blood vessels, lymph nodes, and fat also make up the posterior wall. The dura mater lies anteriorly and the vertebral wall posteriorly to the epidural space. Spinal cord stimulator leads are placed within the epidural space. Revision of the stimulator implantation is very common secondary to lead migration and breakage. Chronic monitoring of the patient following implantation, including adjustment to the stimulator settings and battery replacement is often necessary. Mental healthcare disorders are associated with worse outcomes after spinal cord stimulator implantation. Many insurance companies require psychological screening before the placement of the stimulator. Although severe complications following the installation of a spinal cord stimulator are rare, they can be significant. Various types of stimulators and electrical impulses are used to provide pain relief.įurther research will determine if one type of stimulator is superior compared to another. There are various indications for implanting a stimulator, but it is most commonly done following failed back surgery.

After a percutaneous trial, a permanent stimulator is installed. Patients can have long-lasting pain relief following the procedure. Stimulators have been used for the treatment of both neuropathic and ischemic pain. Spinal cord stimulator implantation is usually reserved for patients who have failed various forms of conservative and pharmacological treatment options. The implantable device offers a nonpharmacological approach to various pain conditions. Spinal cord stimulators are designed to treat chronic pain.
