Dorsal Column Stimulation: A Guide to Understanding This Pain Relief Treatment

Spinal cord stimulation is a minimally invasive treatment option that has been shown to be effective in relieving chronic pain. The process begins with a trial period, during which patients receive a temporary spinal cord stimulator implant to test its effectiveness.

During the trial period, which typically lasts between 4-7 days, patients are able to assess how well the stimulator works to relieve their pain at home. The device is connected to leads that are inserted through a hollow needle into the epidural space or spinal canal under x-ray guidance. When activated, the device sends impulses that block pain messages to the brain.

The trial period helps guide doctors in determining whether permanent implantation of a spinal cord stimulator is indicated. Patients typically have two to three years to live with the device before considering removal. While there is no objective way to gauge pain levels, surgeons aim for at least a 50% reduction in pain when initially implanting a spinal cord stimulator.

The mechanism of action behind dorsal column stimulation involves the antidromic activation of dorsal column fibers, which activate inhibitory interneurons within the dorsal horn. This helps to relieve chronic pain and improve quality of life for patients.

Dorsal column stimulators have been shown to be effective in treating a range of chronic pain conditions, including complex regional pain syndrome (CRPS). According to population-based studies, CRPS affects between 5 and 26 per 100,000 people per year.

Overall, dorsal column stimulation is a promising treatment option for patients suffering from chronic pain. With the ability to assess its effectiveness through a trial period, patients can make an informed decision about whether this treatment is right for them.
