The role of the scapula in preventing and treating shoulder instability

摘要: The shoulder is a closed-chain mechanism that balances the mobility required by ranges of motion in normal activities with stability to act as stable ball and socket base for those activities. scapula plays key roles being mobile enough place glenoid optimal relation humerus facilitate concavity/compression coordinated muscle activation compress into glenoid. Scapular dyskinesis alters these frequently present many types glenohumeral instability. It may create or exacerbate abnormal kinematics Clinical evaluation methods can demonstrate scapular dyskinesis, if present, rehabilitation should be included non-operative, preoperative, post-operative treatment. Rehabilitation performed specific protocols more successful muscle-predominant instabilities such multidirectional instability repetitive microtrauma Level evidence V.
