Enrollment: 60
Sex: ALL
Minimum age (years): 18
Maximum age (years): 50
Standard ages: ADULT
Accepts healthy volunteers: no
Time perspective: CROSS_SECTIONAL
Sampling method: NON_PROBABILITY_SAMPLE
Study population: Sixty subjects (36 males and 14 females, age: 22.5 ± 2.6) were recruited.Potential participants from outpatient clinic in a University hospital and local internet media were evaluated and recruited. They read and signed the informed consent approved by the Hospital institutional review boards.

Brief summary: Study Design: Clinical measurement (cross-sectional)

Objectives: The purpose of this study was to investigate the reliability and validity of the novel scapular dyskinesis classification test.

Background: A visual-based clinical assessment with sufficient reliability and validity to identify scapular dyskinesis provides information for rehabilitation treatment.

Methods: A visual-based palpation method was evaluated by two independent physiotherapists in 60 subjects with unilateral shoulder pain to test reliability. This method classified the scapular movements during arm raising/lowing movements in scapular plane as single abnormal scapular patterns (inferior angle/ medial border/ superior border of scapula prominence and abnormal scapulohumeral rhythm) or mixed abnormal scapular patterns. Different patterns of scapular dyskinesis were also validated by corresponding alternation of the scapular kinematics and muscular activities assessed by electromagnetic motion-capturing system and surface electromyography (EMG).
