Spinal cord injury: Using cortical targets to improve motor function

A main goal of rehabilitation strategies in humans with SCI is to strengthen transmission in spared neural networks. Although neuromodulatory strategies have targeted different sites within the central nervous system to restore motor function following SCI, the role of cortical … Continue reading

Interaction of reactive astrocytes with type I collagen induces astrocytic scar formation through the integrin–N-cadherin pathway after SCI

Central nervous system (CNS) injury transforms naive astrocytes into reactive astrocytes, which eventually become scar-forming astrocytes that can impair axonal regeneration and functional recovery. This sequential phenotypic change, known as reactive astrogliosis, has long been considered unidirectional and irreversible. However, … Continue reading

Induction of immune tolerance by short-course immunosuppresion after spinal grafting of allogeneic neural precursors in pigs with previous chronic spinal cord traumatic injury.

Current clinical protocols use transient or continuous immunosuppression in patients receiving allogeneic neural precursor grafts for treatment of a variety of neurological diseases, including spinal trauma, stroke or ALS. At present there is no solid evidence, however, that would confirm … Continue reading

Promoting targeted reinnervation of phrenic motor neurons and restoration of respiratory function using BDNF after SCI

We are working a novel approach to promote regrowth of damaged descending bulbospinal respiratory axons and reinnervation of their correct phrenic motor neuron (PhMN) targets after cervical spinal cord injury (SCI). Cervical SCI, which occurs in more than half of all … Continue reading

New Pathways for Recovery of Function Following Paralysis

We are dedicated to developing disease and injury specific devices to help restore optimal physiology function in individuals suffering with paralysis due to injury and illness. We accomplish this by enabling the reactivation of damaged and dormant neural circuits through … Continue reading

The Impact of combination biologics on treadmill quadrupedal locomotion after spinal cord hemi-contusion in non-human primates

Introduction. Non-human primates can be trained to ambulate on a treadmill. Cervical contusions lead to both upper and lower extremity functional deficits. These can be analyzed in a coupled manner using kinematic tracking of forelimb and hindlimb joint cycles. We … Continue reading

Oxygen improves blood flow, restores more function in spinal cord injuries

A new discovery at the University of Alberta will fundamentally alter how we view spinal cord function and rehabilitation after spinal cord injuries. Neuroscientists found that spinal blood flow in rats was unexpectedly compromised long after a spinal cord injury … Continue reading

Discovery Offers New Hope to Repair Spinal Cord Injuries

By Dana G. Smith, PhD / Gladstone News / April 24, 2017 Scientists at the Gladstone Institutes created a special type of neuron from human stem cells that could potentially repair spinal cord injuries. These cells, called V2a interneurons, transmit … Continue reading

Robotic platform maximizing gravity-dependent gait interactions to train standing and walking after neurological disorders

Gait recovery after neurological disorders requires re-mastering the interplay between body mechanics and gravitational forces. Despite the importance of gravity-dependent gait interactions for promoting this learning, this essential aspect of gait rehabilitation have received little attention. Here, we introduce a … Continue reading

Gait rehabilitation enabled by epidural electrical stimulation of lumbar segments in a person with a chronic incomplete SCI

Various studies in animal models showed that robot-assisted gait rehabilitation enabled by epidural electrical stimulation of the lumbar spinal cord improves the recovery of leg motor control after spinal cord injury. Recent studies showed that this stimulation is also capable … Continue reading
