Ischemic conditioning is a phenomenon in which an organ exposed to a controlled, short-term, local, sublethal ischemia protects from subsequent ischemia. Remote ischemic conditioning is another more practical approach where transient ischemia and reperfusion applied to a remote organ or tissue, protects other organs or tissues from further episodes of lethal ischemia/reperfusion injury. Remote limb ischemic conditioning (RLIC) is a clinically feasible way of performing remote ischemic conditioning where alternating, brief ischemia and reperfusion is delivered with cyclic inflation and deflation of a blood pressure cuff on the arm or leg.~The overall goal of this research is to use ischemic conditioning to enhance muscle power, motor leaning, and mobility in children with CP. Our previous work demonstrated that when paired with strength training, RLIC improved muscle strength and activation in healthy, young adults and motor learning in healthy older adults. The current study extends that work to determine if RLIC enhances muscle power, dynamic balance, and walking performance in children with CP. This Phase II study will yield the necessary information to design and execute subsequent randomized controlled trials in children with CP as well as other neurological conditions.
The purpose of this research study is to determine if remote limb ischemic conditioning (RLIC) can increase skeletal muscle power, enhance learning of motor (dynamic balance) task, and improve walking performance in children with cerebral palsy (CP).
