Inflammation is the main painful cause in the shoulders with a wear of the cuff, especially because the absence of tendon of the cuff favors the rise of the head under the acromion therefore the conflict with this bone.
It seems logical to try to reduce it (or even disappear).
The physiotherapist, by a work of referral of the humeral head (decoaptation) is able to limit the inescapable rise of the bone of the arm (humeral head) under the acromion (part of the scapula realizing the bone ceiling above the cap) which explains the friction of the cap so the inflammation.
