Additionally, my understanding of my daily movement tasks and recovery goals have been clearly identified and explained by my medical team. I would add that none of those folks share your opinions about the toes fellas. Given the choice I believe in their expertise because it is leading me to a full recovery, Yours by comparison is woefully off the mark. Not that I expect internet chat participants to be their equal, you aren't. And that's o.k. until you cross a line and claim otherwise. I for one don't believe you when it comes to this subject.
Jasp, more vaguerie and insinuation but no specifics. Are you telling us that the muscle experts are saying you can lever your body forward from an aft state by lifting the feet? You're saying one lifts their feet, levers off the top of the boot and moves the com forward. Yes? This is what we dispute.
Sorry about your rehab. The foot is complicated and this is partly why we're against lifting the foot as a tip or mantra. You're going to lock up the foot in all sorts of undesireable ways. Skilled skiers might do it briefy as a cue and move on. The less skilled and over thinkers will get all out of sorts and destroy balance and foot movement while accomplishing nothing.
Those who are clenching their toes have already locked up their ankle. It's quite hard to clench toes and close the ankle. So, "lifting the toes" might help. Having them lift the whole fiit to the top of the boot changes one locknup state for another. Possibly it's less bad, but both are poor functioning states.
The Lindsey sequence was used to show what? She's retracting at transition so obviously her feet would be lifted there. This moves her aft not shins into front which is the stated goal of the foot lifters.
The muscles used for dorsiflexing are simply not strong enough. Though I do think the muscles used for plantar flexion are strong enough to move the body back. That may be part of the problem -people pushing back, away from direction of travel because they don't like loss of friction on the feet and the sensation of falling.
You can believe what you want. I teach expert level lessons almost everyday and it has been my experience that the lifting the foot cue works really well for a lot of students. It has also been my experience that when I activate the AT muscle and the CM moves forward that I generate shin pressure and the ball of the foot is pressured down against the bottom of the boot. I could see how if your boots don't fit well or you activate the TA and don't move the CM forward that you would feel foot pressure against the top of the boot and pressure on the heel as you were skiing in the back seat.
Well this is what we dispute. You are not moving your com forward shin into boot because you lifted the foot. You move your com forward because you allowed it to move forward. If you did not allow it to move forward lifting the foot would just put more pressure on the heel, ball of foot looses contact with the ground plane. Plus you have locked the foot up and made it less able to react and assist in balance. Now more of a club foot or even peg leg as the heel is the contact.
So what exactly do you tell these students? Lift the foot when? Also, when do they stop lifting the foot? That's the difference with advanced students. They'll stop doing something on their own when it doesn't work. Who knows what they're actually doing in the boot. Clearly they don't always lift the foot the whole time they're skiing. So it's a parlor trick?
Thanks for the skiing comment btw.
Advanced students can be like young kids in a way. You give them one thing and the may ydo another that works but that thing you gave was a cue. Young kids do all sorts of things that somehow get the skis to work. I've seen 5 and 6 year olds who ski pretty well fall in soft snow and their foot comes out of the boot, boot still in binding.
