The rest that's best- the shoulder

Subacromial pressures vary with simulated sleep positions: Journal of Shoulder & Elbow Surgery, 10-10; Werner et al..

The researchers studied subacromial pressure in subjects side lying, prone, and supine.  Both the side lying & prone positions place at least one arm in an abducted and/or internally rotated positions for 8 hours at a clip.  Not suprising they increase subacromial pressures greater than the supine posture.  The authors were studying this in the context of the post surgery environment, but I think it's safe to assume the same happens in the throwing athlete recovering from a tough day of practice. 

It's interesting when 2 years ago researchers were studying sleeping posture relationship to kidney stones, the side lying position was again implicated in 88.2% of patients.

But yet the side lying position is often advocated in patients with low back pain, and the back to nature primal enhusiasts.

I don't know, when I sleep I'm flopping all over the place like a fish.  Does anyone know if a sleeping position can be taught?

Joe, Check with some submariners from WWII on sleeposition training.
On another note, I have started doing some reto-treadmill and lateral treadmill work with a 14% grade and my knee pain has subsided. I definitely feel quads and calf muscles engaged. I have been doing it for a little over a week-can it improve that quickly? Martin

Remember Jack the Neuro returns way before the muscular. Sure it is possible.
