Hi Wes,
I am a 2nd year Physio student from the UK, I can give you information on where you are in the healing process with regards to your shoulder. That might be helpful for keeping active.
You haven't stated your age (or any previous medical history or contraindications) but I presume as you are actively playing hockey and football you are fit and in reasonably good health.
14 days post-surgery = Proliferation Stage in healing (this takes up to 60 days).
Your shoulder symptoms should present similar to -
1. Reduced pain
2. Reduced swelling and bruising
3. Active Range of Movement increasing but not full
4. Muscle strength still reduced / due to pain
5. You may feel afraid to move your arm / shoulder
Treatment Goals
1. To control pain and swelling (using ice or contrast heat and ice)
2. Continue to protect the joint / surrounding tissue (using tape, or protective strapping)
3. Early return to movement
4. Increase - muscle strength, active stability of joint, mobility and functional range of movement. (via graded mobilisations, massage, graded exercise programme)
So bearing all this in mind, I feel that (unless you have been given conflicting information) that it would be ok to use your stationary bike.
I think the point being that you shouldn't lean on your affected shoulder (due to your muscle strength being reduced and the fact that it was a labrum tear - so right inside your glenohumeral (shoulder) joint). Excessive pressure on to this area WILL aggravate it, slow your recover and cause complications.
Ensure you are only using your legs and not weight bearing through your shoulders.
Walking's fine....put your ipod on and go for a good walk (boring I know....but it's NOT sitting on your ass !!)
Some simple gym stuff for core and legs.....obviously the longer and more intensely you exercise....the more chance of your shoulder swelling (due to the increase in heart rate and blood pressure).
A friend of mine who continued running (to the same intensity) while recovering from a fractured wrist complicated his recovery as his wrist became very swollen after exercise.
So this is really down to you, a bit of suck it and see....but air on the side of caution.....unless anyone with experience can correct me ??
Obviously....if you feel any pain....STOP immediately, if your symptoms in your shoulder change....STOP....common sense stuff really.
Sorry if this all seems a little long winded....but it should help you understand your recovery better.
Good luck
