Glenohumeral subluxation in hemiplegia: An overview

In case this is one of your problems, they do talk a bit about shoulder pain which was one of my problems although my shoulder never subluxed.
This has nothing to do with chiropractic subluxation.

The shoulder complex consists of four separate joints,
which afford it incredible mobility in all planes of motion,
but at the expense of its stability. The glenohumeral joint
(GHJ) relies on the integrity of muscular and capsuloligamentous
structures rather than bony conformation for its
stability [1]. Injury or paralysis of muscles around the
shoulder complex may lead to GHJ subluxation. Glenohumeral
subluxation (GHS), a frequent complication for
patients with a poststroke hemiplegia, is reported to be
present in 17 to 81 percent of patients with hemiplegia
following stroke [2], However, GHS’s role in poststroke
complications is still controversial. Although the impact
of GHS on the development of shoulder pain (SP) and
upper-limb functional recovery has not been completely
explained, a number of authors [2–6] consider GHS an
important source of SP. Moreover, several recent reviews
focused on SP describe GHS management as the main
intervention to prevent SP [2,5–6]. Thus, although GHS is
probably the most cited problem causing shoulder complications
after stroke, no paper is available that focuses
directly on this problem and describes in detail the main
aspects of the origin, assessment, or treatment of this frequent
and poorly understood complication.
This paper intends to—
• provide an extensive overview on GHS,
• help explain its role in poststroke complications,
• report the reliability and validity of clinical evaluations,
and
• summarize the effectiveness studies on its prevention
and management.
