Non-invasive Therapy to Drive Nerve Regeneration

Sponsor: University of Alberta

Summary

Peripheral nerve injuries are common and often associated with poor outcomes including incomplete repair, debilitating pain states and compromised function. Although nerve regeneration can be enhanced by brief electrical nerve stimulation at the time of or before surgical repair in rodents and humans, this approach is invasive. Acute intermittent hypoxia, breathing alternate cycles of regular air and air with \~50% normal oxygen levels (11% O2) is an emerging, promising non-invasive therapy promoting respiratory and non-respiratory muscle function in spinal cord injured rats and humans. Because the entire body is exposed to this therapy, it has the potential to globally impact the nervous system beyond just controlling respiratory and leg function in spinal cord injured patients. Thus, the investigators hypothesized that an acute intermittent hypoxia paradigm similar to that used for spinal cord repair will improve peripheral nerve repair in a manner akin to electrical stimulation, including its impact on expression of regeneration-associated proteins - a predictor of nerve growth states. In recent studies the investigators found this to be the case and now propose to continue these promising studies by performing a pilot clinical trial evaluating this form of treatment on patients with compromised hand function due to severe carpal tunnel syndrome. The goal is to improve nerve repair outcomes in the least invasive and optimal manner.
