ACL Tears & the Brain

"Anterior Cruciate Ligament Deficiency Causes Brain Plasticity, Kapreli et al."
AJSM, 12-09

In the April 2005 "Journal of Orthopedic Research", the ACL in mice was found to have a direct connection with the spinal cord, brain stem, & cerebellum.

This research inspired some Greek researchers to investigate this phenomenon in humans. Some key brain MRI findings in ACL deficient athletes:

-visual information contributes more to the configuration of movement.
-these athletes unconsciously "plan" their movement.
Is it safe to assume this phenomenon goes on with other joint instabilities? Let the others argue about what squat is good or bad or whether to suck your belly button in or not. We'll stay on the functional path.
