While recognition of surviving pathways in complete injuries has tremendous implications for SCI rehabilitation, currently no effective treatments exist to promote or restore touch perception among those with discomplete SCI. The proposed study will address this need by developing and testing a novel intervention that can provide touch restoration via the primary source of sensory perception: the brain.Complete spinal cord injury (SCI) is associated with a complete loss of function such as mobility or sensation. In a recent discovery we revealed that 50% of people with complete SCI still have surviving somatosensory nerve fibres at the level of the spine. For those with complete SCI this is hopeful news as it means — contrary to previous belief that communication to the brain had been severed by injury — that the brain is still receiving messages. This new SCI type is labelled “discomplete SCI” — a SCI person who cannot feel touch, but touch information is still forwarded from the foot to the brain.
The project will use virtual reality (VR) in a way it has never been used before. We will develop the first immersive VR interface that simultaneously enhances surviving spinal somatosensory nerve fibres and touch signals in the brain in an effort to restore touch perception in people with discomplete SCI. In other words, immersive VR is being used to re-train the brain to identify the distorted signals from toe to head as sensation (touch). For example, participants will receive touch simulation in the real world (e.g., their toe) while at the same time receiving corresponding multisensory touch stimuli in the virtual world (e.g., experiencing walking up to kick a ball).
This project is the first effort worldwide to restore touch sensation in 50% of individuals with complete injuries. The outcomes to be achieved from the current study will represent a cultural and scientific paradigmatic shift in terms of what can be expected from life with a spinal cord injury. In addition, the project allows potential identification of brain mechanisms that may ultimately represent direct targets for acute discomplete SCI rehabilitation, including efforts to preserve rather than restore touch perception following SCI.
RESTORE consolidates the expertise of scientists, clinicians, VR developers and stakeholders from NeuRA and UNSW School of Psychology (A/Prof Sylvia Gustin, Dr Negin Hesam-Shariati), John Walsh Centre for Rehabilitation Research, Kolling Institute and University of Sydney (Prof James Middleton, Prof Ashley Craig and Prof Jim Elliott), Virginia Commonwealth University (A/Prof Zina Trost), Immersive Experience Laboratories LLC (Director Corey Shum) and James Stanley.
If you are interested in being contacted about the RESTORE trial, please email A/Prof Sylvia Gustin (firstname.lastname@example.org) and include your name, phone number, address, type of SCI (e.g., complete or incomplete), level of injury (e.g., T12) and duration of SCI (e.g., 5 years).
This basic science project aims to examine the behaviour of human motoneurones during sustained activation to reveal their mechanisms of recovery after activation. We will take the fundamental findings from this study and compare the behaviour of motoneurones innervating muscles affected by neurological injury such as spinal cord injury and stroke.
Respiratory complications are the major cause of death for people with spinal cord injuries. People with a high level spinal cord injury are 150 times more likely to die from pneumonia than the general population. This is because after high level spinal cord injury, people have a reduced ability to cough and to clear secretions from the lungs. The major group of muscles that produce a cough are the abdominal muscles. If the abdominal muscles are paralysed after spinal cord injury then the strength of the cough will be severely reduced. In our lab, we are looking at ways to improve cough in people with spinal cord injury by using surface functional electrical stimulation of the abdominal muscles. We have shown that this type of stimulation can improve cough significantly. We are now looking for ways to further improve cough through muscle training as well as ways to develop a portable stimulator that would allow independent activation of a cough.
