frozen shoulder origin?

Hi Bernard,
Do you think pecs and pecs alone are the culprits? I'd love to see a picture of latissimus...

Unfortunately, the image is not really well done! I tried to put pecs and latissimus dorsi but I failed. must add some legend?

try to do the levators!

:oops: It seems that I provided not the good ones (images).

Can you explain what goes wrong with lat dorsi and the pecs?

Why do they react in such a way as to cause such pain? Is there any evidence that they suddenly become hypo/ertonic?

Sorry - I see them purely as secondary to a much bigger picture.

Bernard.....

I can barely recall coming across shoulder pain where the pec/s and LD are actively sustained to prevent abd.-though I have seen those ms when a bit tight. I would argue the tight muscle is purely a reaction to pain, causes no pain in itself and shortens because of lack of functional movement in the shoulder.
Do you think it contributes to/causes the loss of ROM?

You will have a tricky time, sea otter, convincing me that muscles are a culprit in any sort of pain.....but, mostly, I will always consider other opinions as valid and interesting.

Also, what about the shoulder which is not injured in any way that can be determined physically - would these big guys still contract actively??

Hi Bernard

Thanks for your reply - I have only just noticed it was way past time to reply!

A bear might be able to catch a sea otter if the otter drifted north on an friendly log and was too busy keeping warm to see the Bear sneaking up!!

For the #10 response - I would say that pain in the shoulder from no specific injury (eg a frozen-type shoulder) might not activate the big guys such as Lat dorsi. I might argue (foolishly) that the pecs and LD would contract (shorten) as a result of loss of abduction and flexion, not pain.

Even in cases of injury to the shoulder, where there is demonstratable damage (such as a severe tear) I do not notice any resistance from pecs/LD on passive movement testing.

I am only mentioning what I see, and I have no literature to back it up, that I have found.

But then, this bear does not care for muscles - rather boring, really - and goes for nerves and the brain! Very tasty, all that slippery axoplasm and chompy cortex.

I have had a tedious day with the big shots from ACT Health trying to develop a mangement plan for a nightmare patient who spends her life ringing and abusing health centres and the hospital....so I am feeling a bit loopy. (Translation: maybe a kangaroo loose in the top paddock_
