Clinical Studies

Pilot Study: Dorsal Root Ganglion Stimulation After Spinal Cord Injury-Related Lower Motor Neuron Damage Rochester, MN
The purpose of this study is to determine if an individual with a SCI below T10 level can benefit from the use of DRG stimulation during task specific training. Changes in motor and sensory activation, motor control/strength, coordination, balance, and gait may be evident comparing before and after the DRG stimulation intervention. Of course, these benefits are dependent upon what the participant’s limitations are at baseline.
Pilot Study: Transcutaneous Spinal Stimulation After Spinal Cord Injury-Related Lower Motor Neuron Damage Rochester, MN
The purpose of this study is to determine responsiveness (present or absent) of spinal sensorimotor circuitry below the level of SCI via transcutaneous spinal cord stimulation (TSCS)-evoked motor evoked potentials (MEPs) in individuals with SCI below T10.

Pilot Study Of Epidural And Dorsal Root Stimulation In Humans With Spinal Cord Injury Rochester, MN
A study to compare electrophysiologic activity of epidural stimulation and dorsal root ganglion stimulation, as well as quantify changes in motor performance with both types of stimulation over the course of 10 rehabilitation sessions.
