4. Discussion
We investigated the effect of rehabilitation with perturbation
training on lower extremity muscle activity and
function in ACL deficient individuals who pass a screening
examination. We specifically chose this subject
population because they have previously been shown to
successfully compensate for their injury and return to
high level activities short-term after completing training
[19]. This investigation was undertaken to help explain
the mechanism which allows for improved dynamic knee
stabilization after training, information that can be beneficial
to rehabilitation protocols for ACL injury.
