General Medical Info on Jaylon Smith Nerve Regeneration

[Doc50]

Foot drop (peroneal nerve palsy) is not an all or nothing condition.
His severity initially was likely a 9 or 10 (0-10 scale), and it's improved quite a bit in the last several weeks.
His deficit now is probably only about a 2, but he therefore still technically has the disorder.

Again, his rehab has been constant and comprehensive, with lots of muscle stimulation to maintain viability and prevent atrophy.
And remember, his push-off is intact, so a major portion of his athletic functionality is preserved, and he's using that daily.

While we fans hunger for info, consider a logical team approach:
1) Media is a huge distraction for them, and is frequently poisonous in many ways.
2) Part of the definition of team includes unity, circling the wagons against all opposition (including mediots, and even fans that want to "throw the bum out" after 1 or 2 bad plays)
3) Such team unity would logically involve a sense a privacy, a resolute commitment keep all issues in house. Bottom line, they play for each other, respect and rely on each other, and and those feelings are steadfast despite the shifting winds of fandom.
4) Therefore, inside info such as injury and non-football issues are not discussed outside the locker room. Certainly, one would not want to ever disclose anything that might give a competitor any advantage.

Garrett and others in interviews this year have uniformly stuck to the same message -- we're staying focused, taking it one play or practice at a time, and avoiding all distractions.

Discipline and patience are virtues.

Why not just not click on the thread, Miley? Or is this like a 'moth to a flame' type thing? Same goes for those that "liked" your post. Masochists? Hate-threadin' it?

Waldo, thanks for keeping us updated, brother. Good bulletin board material for those of us that are interested,

check out doc50 reply

Thanks Waldo, might've missed it if you didn't reply.

Thanks, @Doc50 Excellent stuff, as always

There was a lot of confusion about whether the recovery would be on/off, so your answer is much appreciated.
Google showed push-off (plantar flex) is controlled by different muscles (so different nerves I guess)

I really wish the Jaylon Smith threads would stop. He's not playing this year, and all the other people who have had similar injuries have nothing to do with his rehab and how HE heals.

I can say the same thing about the post you just made. How the hell do you know he is not playing this year? Only God knows.

This is an article that answers some of our questions in reference to Jaylon's update. I will try to get more information from a couple researchers today or tomorrow.

This is original text from US NIH on nerve regeneration. This is general nerve regeneration, not just peroneal nerve injury for Jaylon's case. After the text, I will translate as well as I can for relevant facts:

"EMG testing can be used to demonstrate neurological recovery."
"True axonal regeneration occurs at the site where the nerve has been injured and where axonal degeneration begins [2]. For axonal regeneration to occur, there must be an intact anterior horn cell also known as the motor neuron cell body and an intact channel for regeneration, the endoneurial tube. When axonal injury occurs, the axon distal to the site of injury undergoes Wallerian degeneration, whereas the proximal axonal component usually remains intact. The proximal axon forms a bud that begins to regenerate distally through the endoneurial tube toward the denervated muscle. This process occurs at a rate of 3–4 mm/day so axonal regeneration is length-dependent [3, 4]. Neurological recovery is also dependent on healthy viable muscle tissue. This is necessary for the release of nerve growth factors from denervated muscle. These factors act as a catalyst to stimulate the axon to regenerate. If the denervated muscle becomes fibrotic, these factors may no longer be released. Muscle tissue must also remain viable and electrically active if a regenerating axon is going establish a connection with a functional neuromuscular junction. Chronically denervated muscle will eventually become fibrotic and electrically inactive. This usually happens somewhere between 18 and 24 months."


Take Away Facts:
1. EMG testing can be used for testing nerve regeneration. They are using this with Jaylon and the updates include EMG results are improving. That is a good thing.
2. From other info - there are 2 types of regeneration needed - (1) Regrowing the 6" of the nerve cell that died after the injury and reinnervation of the muscle. (2) Reinnervation of the muscle once the regrowth gets to the muscle.
3. The nerve cell nucleus itself (above the knee) is fine or there would be no regrowth and everyone would be crying already.
4. Regrowth of the nerve axon is 3-4 mm per day. If the growth is having problems, there are surgical options. Since there has been no additional surgery, the regrowth is/did not having major problems.
5. If the nerve takes more than 18-24 months to get to the muscle, we are in trouble because the muscle changes. We are at month 10.

Nice post Waldoputty!!!

Nice post Waldoputty!!!

doc50's 2 posts are much nicer

Pretty sure Stephen and Jerry know, too. But OK.

I'll wait for a real doctor's assessment, thank you.

I listen to doc50. I've told him so. I just haven't waded through the entire thread. Do you want to cite the number of his post so I can go straight to it? Thanks.

And once again you're speaking as if you have intimate knowledge of his medical status.

Multiple insiders have both said he has no ability to lift his foot (drop foot).

Highly doubtful.

No, they have not said that.

Sorry you have to deal with this stuff.
I just ignored them...
