Through the onset of post-stroke motor disorders, the normal scapular function is
compromised. As a result, shoulder pain and associated upper limb dysfunctions
frequently arise after stroke. This review aimed to provide a systematic overview
of available literature on scapular function, i.e. scapular three-dimensional
(3D) kinematics and muscle activity during elevation, in healthy persons, persons
with primary shoulder disorders and post-stroke patients. 3D scapular kinematics
have been widely reported in healthy persons and persons with primary shoulder
disorders, whereby a general pattern of upward rotation and posterior tilt during
elevation has been agreed upon. Results on scapular internal/external rotation
are inconsistent. In a post-stroke population, 3D scapular kinematics are less
frequently reported. Scapular muscle activity has thus far been studied to very
limited extend and firm conclusions could not be drawn. Although 3D scapular
kinematics and muscle activity registrations are being increasingly used, some
general methodological aspects should be considered. While the International
Society of Biomechanics already proposed recommendations on the definition of
upper limb joint coordinate systems and rotation sequences, proper result
comparison necessitates further guidelines on other methodological aspects, i.e.
data collection, processing, analyzing, and reporting.
