hi sweens ;

I think the issue of Trigger point therapy still needs research to support ,sometimes i see triggers as just sensitive neural areas/spots .Just my view .
As for this current shoulder case , i think practical assessing of this case is important ,because we can NOT assess the passive abduction if it is available or not to conclude the tear hypothesis ,because pain sometimes may be severe around shoulder that the motion could be thought of as paralysis or tear .

Cheers
