shoulder locking

[ajay.physio01]

hi
as you are a physio it will be very kind of you if you use the commonly used terminologies and put up your assessment clearly and a bit in detail.then only i feel people could help you out.
bcos the word you used"locking"-doesn't give a clear cut idea whether the patient is having full rom,type of end feel etc etc.i hope you agree with me
cheers

Active ROM of abd:90
flx: 105
PassiveROM of abd:110
flx: 140
Power are for all muscle is :4 within available range
end feel: empty

I think the biomechanics is malfunctioning but could not make out the exact thing.
I feel that his head of humerus "slipps" while going beyond 90degree.and it gets locked while returning to adduction or extension with severe pain.
Not a labrum injury or other injury.

any literature related to this then please do attach with reply.

hi friend
so according to you eccentric movements ya movements in the opposite direction are painful.
the anteroposterior translation of humeral head during normal conditions is 4-6mm.the restraints are capsule,labrum-static stabilizers
rotator cuff -dynamic stabilizers-by concavity compression action
so for excess translation/locking to take place any of the structures should be affected
have you observes the scapula kinematics
strangth of scapula stabilizers
rotator cuff special tests
tests for labral injuries
SLAP lesions
history of any trauma
general laxity
