First impressive Jaylon video

[Melonfeud]

So here's a couple of questions...and this may not be the thread for it.

Let's say that Jaylon's nerve never completely refires....but fires some. You could argue that it is (well, we can obviously argue about anything). Could someone make an AFO that operates bionically based on the signals it is getting? If not now, in the future? And at what point will the NFL limit such bionic devices?

Oh my...look at the questions I just typed. It's only February. This off season is going to kill me.

Didn't you even see that 'robot wars' on t.v.? Cuz that's the probable evolution once the biomechanics threshold is breached and goes lame stream

WOW! Just WOW!

Got to love the human mind and it's opinions. Pair that with the Constitution and you get this thread.

I would love to be setting in front of Jaylon and observe him reading this forum.

lol jaylon may well be given his interest in social media
nothing like checking out the views of the biggest fans who spend at least 1 per day on the website.

and I am well aware of what a leaf spring does and automotive ones do not give very much even under load.

There are aftermarket leaf springs with way more travel than the ones in the image. The original monster trucks had some with a very large amounts of travel. The performance versions have a much bigger radius (arch) and a much bigger back shackle to allow the extended movement.

I have a flat piece a plastic (not sure what type) that's about 1/16" thick I clamped it to a workbench with 12" overhanging the bench. I can deflect it down about about 45% and up about 45%. Material engineered for the specific purpose could likely allow a large range of movement.

It does not take a lot of force to return the foot back up. It just needs a little more force than you would get from wearing a thick and tight neoprene ankle brace.

Again, I didn't say he was wearing a brace exactly like the one in the image I posted.

@FuzzyLumpkins

This video came out several months ago when he was known to be wearing the brace. It the part of the video where he is outside that I saw several months ago.

I don't think he can be doing these movements if the brace only has 15 degrees of movement.

Dude, that's your spin it's all coming from you because you have an agenda. There's not a post on this board where I said Smith will never be cleared to practice. Watching you squirm around that fact is hilarious. lol You got caught twisting my comments, putting your own spin on them and you're still doing it.

I've seen this posted a couple of times and I'm having a hard time trying to figure out what is agenda is other than giving the board info on Jaylon Smith? Being hopeful that he will pan out? I don't see any personal agenda. He wants this pick to workout for both Dallas and Jaylon which would mean it's a win for the fan base. I don't see anything wrong with that. Maybe I'm missing something here.

furthermore on the previous message, i am not aware of a good simple reliable mechanical means for engineering a delay in the spring back.
so to make it a safe return, it would most likely mean a slower return

What your are describing is basically a shock absorber.

The brace in the image has a hinge mechanism with a spring action that pulls the toe-end of the foot up. Even if the spring was really strong, if the hinge was really tight, then the return action of the spring would be slower. The tighter the hinge the slower the return up to the point that if it's too tight the spring won't be strong enough to move it.

right, in my world it is called a spring dampener.
however, that is for the end of the travel.
it does not delay the start of the motion, which if started too early (stiff spring) could interfere with the walking motion.

No, if the hinge is tight, it will slow down how fast the spring returns the foot back. It can slow down both the initial return movement as well as preventing any oscillation at the end of travel (damping).

That was from December and that was also the same time the pics with his nieces without the brace surfaced. The pics with the brace are from training camp in August.

He clearly is not wearing the brace in question there either. His ankles are heavily taped though. If you want to argue with Richiebrace about their product description then have at it but we know the brace that he used to wear did not allow plantarflexion.

The key here is that they used to have him in a hinged brace that did not allow the foot to drop at all when he trained. We have seen him wear it and there is no arguing it. If they changed it to a different brace like you keep wishcasting then that is possible but it also means that he his nerve is firing. Else why change?

@waldoputty

I think they should just install a jumper on the nerve like I would on a circuit board.

I'll offer to do it for them, but it's going to hurt like heck when I start soldering on his leg.

Everything is relative. A monster truck can be 15 feet long. The foot is much smaller. The point is arc of travel.

If you spring load a foot and allow it to travel 45 degrees then it is going to flop all over the place and there is little control because Jaylon would have no control over one direction of motion with a palsy.

Are you saying that there is zero Plantar Flexion in this video?

Break it down with stills and show it. I'm not going to make your argument for you.

It looks to me like he is having to pick up his left knee in an exaggerated motion like people with drop foot do when moving with an AFO. On the kickback his toes are pointed up in a weird fashion.

compare with the angle the right foot lands in the first frame. The gait is not uniform and fluid like it is now.

Very minimal once you consider the leg is at an angle and the camera shot is from the side. Note the appearance of the right angles of the side squares on the cube below when the image is at a similar frame of reference.

That was the beauty of the OP hurdle shot. It was straight on.

I actually the nerve is working better and better

i think the spring would just take time to speed up once it is released.
my point is still why would the rate of the spring action happen to match the other foot.

 

[jobberone]

I'm only using toe(s) as a reference point to the part of the foot where the toe(s) attach. I'm not referring to any actual movement of the toe(s). If you describe the foot in simple terms, one end is the "toe" end and one end is the "heal" end.

I guess I should have said:
The foot rotates with the ankle as the pivot point. Dorsiflexion is the rotation in the direction such that the end of the foot where the toe(s) attach moves up relative to the ground. Plantar Flexion is rotation at the same pivot point but in the direction such that the end of the foot where the toe(s) attach moves down relative to the ground.

In the attached image the red dot is the pivot point for both Dorsiflexion and Plantar Flexion.

I don't need your pictures. The point is no professional speaks of toes when talking about foot drop or the movement of the foot. That's why I brought it up yet the entire thread for the most part is non-professionals speaking a language and topic they don't really know well. And when a professional does speak most of you want to argue.

Which is why I try to stay out of these discussions and why so many others just quit and/or left the site. I'll do a better job.

Anyone trying to determine how Smith will play based off his foot drop/spring in his foot or how his toes are pointed is making a big mistake. Some of what's being posted is cracking me up. LOL His ability to play football at the high level everyone is hoping for will be determined when he puts the pads on and has to make plays on the field.
