If we look at this example more closely, what we see is that the knee begins to cross midline prior to:
- Movement of the foot into a pronated position - root cause being more at the foot and ankle
- Movement of the pelvis into a trendelenburg or corkscrewing position - root cause being more at the core
Glut Med Series:
Use of this exercise allows us to target to the glut medius specifically. As indicated in the video, position of the feet is critical for those with weak gluts will toe out during this exercise which will limit the strengthening that occurs at the hip.
Single Leg Lumbar Hip Disassociation:
Due to the fact that we don't know if this is associated with weakness/endurance issues in the muscles of the hip or proprioceptive issues in the hip, using this exercise targets both strength/endurance as well as proprioception. When done properly with proper hip positioning, we find this results in significant increase in EMG activity of the gluteus medius.
Next week, we will conclude this discussion on single limb training with our examination of what is going on at the hip. If you enjoy this blog, please share with your colleagues and follow us on instagram @ bjjpt_acl_guy and twitter at @acl_prevention. #ViPerformAMI #ACLPlayItSafe
