摘要: Scapula motion is significant for support of the arm and stability shoulder. The effect humeral elevation on scapular kinematics has been well investigated normal subjects, but there are limited published studies investigating adaptations after shoulder arthroplasty. was measured 10 shoulders (eight subjects) with a reverse total joint replacement. measurements were performed using an instrumented palpating technique. Every subject three simple tasks: abduction, in scapula plane forward flexion. Results indicate that, lateral rotation significantly increased (average 24.42% over rhythm) change variable. Despite variability, clear trend correlating performance (R2 0.829). There clearly adaptation patients reason this unclear may be related to pathology or muscle following
