Clinical Trial Summary

The purpose of this study is to evaluate the therapeutic efficacy of microdosing BurstDR stimulation in spinal cord stimulation (SCS) patients with chronic intractable back and/or leg pain.

Description:

Microdosing BurstDR consists of periods during which stimulation is delivered with standard BurstDR stimulation parameters alternated with periods during which no stimulation is being delivered.

In this study the investigators propose to evaluate therapeutic efficacy of BurstDR microdosing, and determine optimal microdosing programming parameters in chronic pain patients, who are eligible for SCS therapy.

Intervention

Device:
• Stimulation will be delivered at with different microdosing setting to identify the optimal parameter values for each patient.
BurstDR spinal cord stimulation will be delivered with different ON/OFF periods to identify the best setting for each patients.
