Efficacy of Spinal Cord Stimulation in Burst Mode in the Treatment of Complex Regional Pain Syndromes Type 1 of the Upper Limbs

Overview

In this study, it is the procedure of spinal cord stimulation in Burst mode, its results and the experience of the patients that are evaluated.

There is 1 "classic" spinal cord stimulation setting that can be problematic in the case of cervical spinal cord stimulation because neck movements tend to trigger paresthesias. It is therefore possible, in a certain number of cases, that these side effects prevent the treatment from being effective. Thus, the development of new modes of spinal cord stimulation, mainly aiming at eliminating these side effects, has proven to be particularly interesting. There are 3 new modes of stimulation: high frequency stimulation which uses very short pulse durations and a stimulation frequency of the order of 1000 Hz, high density stimulation which uses long duration pulses and an intermediate stimulation frequency, and "Burst" stimulation which uses stimulation trains repeated 40 times per second. The Burst stimulation mode preferentially activates pathways in the medial part of the pain matrix, leading mainly to the cingulate cortex involved in modulating the affective, emotional and attentional side of pain. This result should theoretically be felt positively by the patient and his entourage, and the benefit should persist, or even improve with time, contrary to what is often observed with other stimulation modes. In addition, the Burst mode consumes little energy, theoretically less than conventional stimulation. It is therefore not necessary to use rechargeable stimulators, which provides greater comfort for the patient.
