Cross Education for ACL Rehab


The phenomenon of maintaining strength by training your UNINJURED limb when your INJURED limb is immobilised is called Cross Education.


And it potentially has a powerful effect on overall rehab outcome; especially ACLR rehab.


In a recent study by Harput et al (2018), a group of ACL injured patients were divided into 3 groups who all performed the same standardised ACL rehab.


However, one group did 3x extra sessions per week of concentric knee extensions on their uninjured leg for 2 months, another group did 3x extra sessions per week of eccentric knee extensions on their uninjured leg, and the other group did nothing extra (control group).


At 6 months post-op the authors found that the quads strength for the group that did extra sessions of concentric-only knee extensions was 28% greater compared to the control group, and the group that did extra sessions of eccentric-only knee extensions had 31% greater quad strength when compared to the control group!


Take home message: you might be injured, but you also have a healthy opposite limb that can and should be trained as normal - and in doing so, can benefit your currently injured limb in the months ahead
