Neuromuscular Consequences of Knee Arthroscopy

Novel rehabilitation methods, that specifically target decreased muscle activation due to
joint pathology prior to strength training, have elicited greater improvements in muscle
function and self-reported disability compared to traditional therapies. Preliminary
evidence suggests applying cryotherapy to a joint prior to exercise can increase quadriceps
activation. It is unknown if applying cryotherapy and intermittent pneumatic compression can
also increase quadriceps force output and voluntary activation. The purpose of this study is
to determine changes in quadriceps force output and voluntary activation following the
application of cryotherapy and compression. The investigators hypothesize there will be an
increase in quadriceps force output and voluntary activation following the application of
cryotherapy and compression.
