H-reflex in Spastic Lower Limb Cryoneurotomy
Sponsor: Vancouver Island Health Authority
Summary
Spasticity is a common complication after many upper motor neurone disorders. Many surgical techniques have been introduced for patients with refractory spasticity though they are not without peri-operative risks. Cryoneurotomy is another procedure which is cheaper, faster and less invasive in comparison to other surgical interventions. While many studies support the use of cryoneurotomy for pain relief, there are not much studies on use of cryoneurotomy to manage spasticity. The purpose of this study to measure the effect of tibial nerve cryoneurotomy on electrophysiological and clinical spasticity measures in adult patients with spastic equinovarus or equinus foot, who will receive this procedure as a part of their treatment based on spasticity treatment available guidelines. The results will provide us valuable information like how long cryoneurotomy is effective, before regeneration happens.
