Thanx for replying! I didn't think anyone replied because I didn't get an email.... so I am very garteful people replied.
Well, I have been tested twice (emg studies) and the muscle:nerve and nerve:muscle connections are all perfect.
I was tested once (emg) just at the outlet from the spine at L4 nd L2. L4 came back denervated and L2 came back irritated. The neuroligist didn't test the spine the second time so I don't know if L4 is any better.
Some of that left L4 denervation may just be age. I don't know. I am very confused on the subject. The neurologist thinks my problems are myofascial. What I think is that L4 nerves were mildly hurt awhile back, causing initial compensations which then in turn caused myofascial problems caused by the muscle imbalances that resulted.
ok, so I don't understand this. See, if one leg is weaker, I would think that most likely the pelvis & torso will also be unbalanced- I mean, everything will be unbalanced not just the limbs, right?. So even on one leg the person has to make a real effort to keep their hips and shoulders square. Also, if there is any preferential rotation in the spine (and there is in many many people), the person has to be super aware of this.
Ditto for arms- there is subtle torso twisting I would think and it is very difficult to make sure this is the same on both sides. It is also very hard to make sure the trajectory of the weight is the same on both sides- at least for me- because my left shoulder wants to rotate internally and my left shoulder wants to rotate externally etc- I watched myself do the YTWL mobilizations in the mirror and I was horrified to see how different the trajectories were. If I was do that unilatertally, I think I would just keep etching in the mistakes....the machines will at least guide my hands in identical trajectories..
what do I not understand? I know I am usually mistaken- seriously, so I must really be missing something.
I wish I could read something on the subject. I know I was doing a lot of ballet which is at least 50% one-legged work (your version of squats, jumps and straight leg deadlifts) and that is partially what got me into this mess. I am actually MUCH happier on one leg.
I would appreciate any references on unilateral work for correcting muscle imbalances. thanx:)
