Chronic Transcutaneous Stimulation to Promote Motor Function and Recovery in Individuals With Paralysis or Paresis

This is an early feasibility trial to determine whether transcutaneous neuromuscular electrical stimulation, with or without transcutaneous spinal cord stimulation, using an investigational neurostimulation device improves functional arm/hand movements in individuals with paralysis or paresis due to a spinal cord injury or stroke and improves functional arm/hand or leg/foot movements in individuals with paralysis or paresis due to other brain or nerve injuries. In this study, eligible individuals that agree to participate will be asked to attend up to 5 study sessions a week for 1 year (depending on participant availability), with each session lasting up to 4 hours. At the first study session, participants will have their demographic information collected, vital signs assessed, and have measurements performed of their limbs and torso, as appropriate. They will also undergo clinical evaluations and tests to assess their current functional movement and sensation capabilities. During subsequent study sessions, participants will undergo many tasks designed to improve functional movements in paralyzed limbs. Specifically, participants will receive neuromuscular electrical stimulation to the limb(s) and/or electrical stimulation to the spinal cord to evoke specified movements. The stimulation parameters and locations on the spinal column and/or limb(s) that evoke specific movements will be noted. The movements will be assessed with visual inspection, electromyography, and/or sensors. The clinical evaluations and tests to assess functional movement and sensation capabilities will be repeated throughout the study and at the last study session to assess for functional improvements compared to the first study session. Upon completion of these study sessions, the individual's participation in the study is considered complete.

Deep Brain Stimulation in Patients With Incomplete Spinal Cord Injury for Improvement of Gait

Spinal cord injuries are anatomically mostly incomplete, showing tissue bridges of the spinal cord at the injury site. Of the 60% functionally incomplete patients, about half face a life in the wheelchair. Besides conventional rehabilitation, no prominsing further treatment options exist. One of the most plastic systems involved in locomotion is the pontomedullary reticulospinal tract, which is the oldest locomotor command system existing in most vertebrates, including primates. Muscle activation patterns for limb movements are programmed in the spinal cord and have to be activated and coordinated through commands from the so called mesencephalic locomotor region (MLR). The MLR consists of nerve cells in the lower mesencephalic tegmentum sending uni- and bilateral signals through the medullary reticulospinal tracts. Classical physiological studies showed that electrical stimulation of the MLR induce locomotion. For the first time this approach was transferred and recently published in a model of induced incomplete spinal cord injury by the Schwab group. Rats severly impaired in motor hindlimb control with only 10-20% spared white matter, recovered with fully functional weight bearing locomotion under MLR deep brain stimulation (DBS). Even rats with only 2-10% spared white matter regained weight supporting stepping. DBS is a clinical standard treatment option in patients with movement disorders but does not relieve all symptoms. Therefore, small studies of MLR stimulations have been safely used in Parkinsonian patients showing freezing of gait and frequent falls with variable results. In a translational approach, we aim at performing a multidisciplinary phase one clinical trial with 5 patients and incomplete spinal cord injury. With the means of our established universitary setup for DBS treatments the operations will be performed unilaterally under local anaesthesia in the Division of Neurosurgery, USZ, with perioperative electrophysiological recordings, clinical assessments and gait analysis under test stimulation in the Spinal Cord Injury Center Balgrist.
