My son was injured 4 months ago (C6 Asia A) and has made great progress in that amount of time (recently evaluated at C7 Asia C). Recently he has developed controlled movement in his legs but only when the legs are in a stretched position. Therapist are not sure if he is indeed controlling it or if just tone. Does anyone else have experience with this type of movement?
I may have something similar. It's close enough so that I want to "share". I'm T 9 incomplete, so that part would look, at first glance, like it wouldn't relate to his condition. But being 'incomplete' can make for some interesting combinations.
I have only one leg. I lost the other one at the moment that the car hit me - and broke my back, so when I mention my "leg", that's the reason I won't be saying "legs". Here goes,...if I'm sitting up and my leg is bent, but I want to straighten it, I can usually get it to straighten out by laying back in bed. Voila! The leg straightens. Not only that, but it 'stretches' out board straight. There's even a secondary reaction where my stump will immediately follow the full leg with a little mini-stretch of its own.
A physical therapist, the best one I had, felt of the calf of my leg once and mentioned that my leg isn't "flacid". But I assure you, I cannot control my leg. I can't bend it or straighten it. However, by giving it a little push with my hand and then manipulating my upper torso, the impression to a casual observer would be that I had "straightened my leg". One rude hospital aide even loudly and triumphantly announced to her co-workers, "She can move it! I saw her move it!"
I can't do anything else with it, not even after it is stretched out. So, at that point, my condition may be dissimilar to your son's.
