Dear physio in (cyberspace),

I too am interested in your perspectives about this stretch since I am a personal trainer and public servant (during the day).
I injured my shoulder 4 years ago and as a personal trainer and injured dancer I would be interested in your perspectives on how to 1) improve scapula mobility and 2) thoracic mobility. In January 2010 I compressed the ulnar nerve which has affected my ability to use the computer for long periods of time and to type.

I have been working on scapula stability for about 4 years now and have good strength but my scapula mobility is still poor. It seems to get stuck and because it sticks it causes the levator and neck muscles to do more work. I would be interested in advice on potential exercises I could try. I also have poor thoracic mobility but it improves after lying on a foam roller and manipulation from my physio.

Because of the constant flare ups in levator and infraspinatus along with the nerve compression, he is suggesting that I consider a CT scan guided cortisone injection around the nerve root C5/6. I am hesitant because 1) it is invasive, 2) there is a possibility that it may not work and 3) his diagnosis may not be correct. Can anyone shed light on some potential options or considerations other than a cortisone, and how I can increase scap mobility.

Suggestions or literature I can look at to try to increase mobility and considerations other than cortisone are greatly appreciated.
Many thanks in advance.
