Neuromodulation: Simultaneous stimulation of the dorsal root ganglion and spinal dorsal column in the application of complex local pain syndrome

Complex Regional Pain Syndrome (CRPS) is a pain, debilitating, and heterogeneous disease that is often difficult to treat effectively
.
The pathophysiology of CRPS involves a complex network of mechanisms, including peripheral sensitization, central sensitization, cortical reorganization, and inflammation, which makes it difficult to treat underlying causes

Traditional spinal dorsal column stimulation (t-SCS) has been used in CRPS for decades and has achieved good results
.
However, this therapy does have some limitations in the treatment of CRPS

Patient radiography

The study included 4 patients with severe CRPS, all of whom had t-SCS implants

The improvement of average pain by different nerve stimulation modes

In studies using t-SCS and DRG-S at the same time, it was found that there are several potential neural stimulation mechanisms that may help enhance pain relief
.
One mechanism may be related to the dual stimulation system better covering the painful areas of the extremities

Both t-SCS and DRG-S are effective in the treatment of CRPS patients
.
In the study of this article, the simultaneous use of t-SCS and DRG-S has a significant improvement in pain and function compared with either device alone
