Researchers at Indiana University School of Medicine have made several novel discoveries in the field of spinal cord injuries (SCI). Most recently, the team led by Xiao-Ming Xu, Ph.D., has been working to determine how to activate movement after a spinal cord injury at the ninth thoracic level, where nerve fibers from the brain down to the spinal cord are interrupted. Instead of focusing on the injury site, researcher Qi Han and his colleagues modulated the spared lumbar circuits below the injury to improve recovery from SCI, using animal models.
Spinal cord injuries caused by accidents, violence and disease paralyze from the neck down more than 5,000 people every year. In the first few months after injury, some people regain some movement and sensation in their limbs. Those who do not show improvement in the first few months are unlikely to ever recover.
Novel approach also shows promise for autoimmune diseases
Paralyzing damage in spinal cord injury (SCI) is often caused by the zealous immune response to the injury. NIBIB-funded engineers have developed nanoparticles that lure immune cells away from the spinal cord, allowing regeneration that restored spinal cord function in mice.
Researchers from Australia have successfully “rewired” the nerves within the paralyzed arms of some accident survivors and provided them with successful movement of arms and hands.
The results of the study titled, “Expanding traditional tendon-based techniques with nerve transfers for the restoration of upper limb function in tetraplegia: a prospective case series”, were published in the latest issue of the Lancet.
A systemically injectable peptide, which may make it possible to restore lost functions in spinal cord injury patients, is moving toward clinical trials in early 2020.
The treatment, which was developed by Jerry Silver, a professor of neurosciences at Case Western Reserve University’s School of Medicine and advisor for NervGen Pharma, is the culmination of decades of work, and in pre-clinical studies, it has shown robust results in animal models.
Spinal cord injury (SCI) commonly results in paralysis from the injury site down, even when the spinal cord hasn’t been severed completely. The remaining nerve cells that might bridge the gap appear to switch off, resulting in total loss of muscle control and sensation. Scientists at Boston Children’s Hospital have now identified a small molecule drug that effectively reactivates the signaling pathways between these remaining nerve cells and the brain, restoring walking ability in mice that had been paralyzed by SCI.
After suffering a severe cervical spinal cord injury from a bad fall at work, Scott McConnell had little function remaining in his hands and arms.
Today the Epidural Stimulation Procedure brings new hope for Patients with Spinal Cord Injury.
Third patient recovers two motor levels; three of six (50%) patients in AIS-A 10 million cell cohort have now recovered two motor levels on at least one side
FREMONT, Calif., June 13, 2017 /PRNewswire/ — Asterias Biotherapeutics, Inc. (NYSE MKT: AST), a biotechnology company pioneering the field of regenerative medicine, today announced that new 9-month follow-up data from the AIS-A 10 million cell cohort in the company’s ongoing SCiStar Phase 1/2a clinical trial shows three of six (50%) patients have now recovered two levels of motor function and previously-announced improvements in arm, hand and finger function at 3-months and 6-months following administration of AST-OPC1 have been confirmed and further increased at 9-months.
A new discovery at the University of Alberta will fundamentally alter how we view spinal cord function and rehabilitation after spinal cord injuries (SCI). Neuroscientists found that spinal blood flow in rats was unexpectedly compromised long after a spinal cord injury (chronically ischemia), and that improving blood flow or simply inhaling more oxygen produces lasting improvements in cord oxygenation and motor functions, such as walking.
Previous work had shown that while blood flow was temporarily disrupted at the injury site, it resumed rapidly, and it was more or less assumed that the blood flow was normal below the injury. This turns out to be wrong.
