WHAT DORSAL COLUMN STIMULATOR TRIAL TRIAL

To our knowledge, this is the first study to compare these 2 neurostimulation methods in patients with CRPS confined to the knee.

WHAT DORSAL COLUMN STIMULATOR TRIAL TRIAL

After finishing the trial period, 10 patients (83.3%) preferred DRG stimulation and 2 (16.7%) preferred DC stimulation (P = 0.04).

Patients with a successful trial period with one or both stimulation methods received a fully implantable system. After receiving DC and DRG stimulation during a trial period of 16 days, patients were asked which of the 2 methods they preferred. DRG stimulation in treating chronic pain due to CRPS confined to the knee.Ī prospective, observational crossover cohort study was conducted comparing 2 methods of neurostimulation, in randomized order, in patients with CRPS confined to the knee. Therefore, this study explores patients' preference for DC stimulation vs. Although results with dorsal column (DC) stimulation in patients with CRPS confined to the knee are often disappointing, the availability of dorsal root ganglion (DRG) stimulation may provide new opportunities for this complaint. Neurostimulation is an accepted treatment for CRPS. Theorized anatomical constraints have included the close relationship with the dorsal columns to the dorsal root fibers, the increased thickness of the dorsal cerebral spinal fluid at T8T9, and the size of the L1 and L2 dermatomes with their close proximity to the T12 dermatome. Patients with complex regional pain syndrome (CRPS) confined to the knee are often therapy resistant.
