Filter by:The PRIME Study is a first-in-human early feasibility study to evaluate the initial clinical safety and device functionality of the Neuralink N1 Implant and R1 Robot device designs in participants with tetraparesis or tetraplegia. The N1 Implant is a skull-mounted, wireless, rechargeable implant connected to electrode threads that are implanted in the brain by the R1 Robot, a robotic electrode thread inserter.
The purpose of the current study is to evaluate whether a home-based, telehealth-supported intervention combining Blood Flow Restricted Exercise (BES) and Transspinal Stimulation (TS) will improve motor and functional abilities greater than BES+sham TS in persons with chronic, incomplete tetraplegia.
Spinal cord associative plasticity (SCAP) is a combined cortical and spinal electrical stimulation technique developed to induce recovery of arm and hand function in spinal cord injury. The proposed study will advance understanding of SCAP, which is critical to its effective translation to human therapy. The purpose of the study is to: 1. Determine whether signaling through the spinal cord to the muscles can be strengthened by electrical stimulation. 2. Improve our understanding of the spinal cord and how it produces movement. 3. Determine whether spinal surgery to relieve pressure on the spinal cord can improve its function. Aim 1 is designed to advance mechanistic understanding of spinal cord associative plasticity (SCAP). Aim 2 will determine whether SCAP increases spinal cord excitability after the period of repetitive pairing. In rats, SCAP augments muscle activation for hours after just 5 minutes of paired stimuli. Whereas Aims 1 and 2 focused on the effects of paired stimulation in the context of uninjured spinal cord, Aim 3 assesses whether paired stimulation can be effective across injured cord segments. Aim 3 will incorporate the experiments from Aim 1 and 2 but in people with SCI, either traumatic or pre-operative patients with myelopathy in non-invasive experiments, or targeting myelopathic segments in intraoperative segments.
Locomotor training is often used with the aim to improve corticospinal function and walking ability in individuals with Spinal Cord Injury. Excitingly, the benefits of locomotor training may be augmented by noninvasive electrical stimulation of the spinal cord and enhance motor recovery at SCI. This study will compare the effects of priming locomotor training with high-frequency noninvasive thoracolumbar spinal stimulation. In people with motor-incomplete SCI, a series of clinical and electrical tests of brain and spinal cord function will be performed before and after 40 sessions of locomotor training where spinal stimulation is delivered immediately before either lying down or during standing.
