Purpose : To describes the important aspects of scapular movement and function used when applying PNF technique to the upper limb and scapular. Method : The scapular was a very important roles in the upper limb movement. This study summarizes the physiologic movement of scapular to the PNF upper extremity patterns or scapular pattems. Result : The shoulder joint has the most freedom of range of motion in the human body, composed of the glenohumeral joint, the subacromial joint, the acromioc1avical joint, the stemoclavicular joint. the scapulothoracic joint, the costostemal joint, and the costovertebral joint. During upper limb movement, the scapular position change at the stemoclavicular joint and the acromioclavical joint. This concerted motion was characterized by scapulohumeral rhythm. In clinical situations, it is import to understand factors affect the scapulohumeral rhythm so that optimal evaluation and therapeutic intervention can be devised. Conclusions : The scapular movement depend on the proper and coordinated contraction of muscles. Physical therapists need to understand the normal scapular movement relationships of the scapulohumeral rhythm under different interventions for PNF techniques application.
