Condition: Spasticity as Sequela of Stroke · Sponsor: Sue Peters
Spasticity can make regular daily activities difficult or impossible. Cryoneurolysis is a new technique to treat spasticity that is currently being tested. For this technique, a needle is inserted alongside a nerve implicated in spasticity. The needle then freezes and causes the nerve to break down. The nerve breaking down seems to provide relief for spasticity. The investigators are interested in testing the long-term effects of cryoneurolysis on the function of the brain over six months after treatment. The investigators are testing the brain's function using transcranial magnetic stimulation (TMS) which involves a magnet activating specific parts of the brain that cause muscles to fire; magnetic resonance imaging (MRI) which uses to examine brain structure; functional near-infrared spectroscopy (fNIRS) to examine brain function. The investigators believe that there will be a change in these measures that are related to the long-lasting effects of cryoneurolysis. Cryoneurolysis is not a part of standard care after stroke but is approved in Canada for patients. It has been used extensively in the past for treating pain. TMS is a way of studying how the brain sends signals to muscles to make movement. During these sessions, a researcher will use a magnet to turn on specific neurons in the brain that will cause muscles to contract. The investigators can study the way eyes and muscles respond to better understand how the brain is sending information about moving the body to the…
