Functional Kinesiology of the Shoulder Girdle Joseph Burris, MD Associate Professor of Clinical PM&R Director, Amputee Rehabilitation Program Overview • Bony skeleton • Anatomic/functional articulations • Other anatomic considerations • Motor control—muscles • Functional kinesiology Anatomic articulations SC Joint Reinforced by: • Sternoclavicular ligament • Costoclavicular ligament • Interclavicular ligament Anatomic articulations • Elevation/depression • Abduction/adduction (pro/retraction) • Anterior/posterior tilt Anatomic articulations • Acromioclavicular joint • Medial-lateral rotation • Anterior-posterior tilt Functional articulations • Suprahumeral joint • Coracoid • Acromion • Coracoacromial ligament Functional articulations Clavicle Serratus anterior ¢ Scapulothoracic joint muscle ¢ Scapula to thorax J Subscapularis muscle Functional articulations • ST joint • Structures to maintain integrity of AC and SC joints Functional articulations • Elevation/depression • Abduction/adduction • Upward/downward (lateral/medial) rotation • Anterior/posterior tilt Other considerations Other considerations ‘©OMMG 2001 Scapulothoracic and scapulocervical muscles • Serratus anterior • Trapezius • Rhomboid major/minor • Pectoralis minor • Levator scapulae Scapulohumeral muscles • Deltoid • Supraspinatus • Infraspinatus • Teres minor • Subscapularis • Teres major • Coracobrachialis Thoracohumeral muscles • Latissimus dorsi • Pectoralis major Shoulder girdle movements • Upward rotation (lateral rotation): movement of glenoid fossa superiorly with inferior angle of scapula sliding anterolaterally along thorax • Downward rotation (medial rotation): movement of glenoid fossa inferiorly with inferior angle of scapula sliding posteromedially along thorax Shoulder girdle movements • Anterior tilt: anterior movement of superior border of scapula along with posterior movement of inferior border of scapula to maintain scapulothoracic relationship during scapular elevation • Posterior tilt: posterior movement of inferior border of scapula along with anterior movement of inferior border of scapula to maintain scapulothoracic relationship during scapular depression Scapulohumeral rhythm Glenohumeral movements • Lateral (external)rotation: lateral movement of the humerus around its longitudinal axis • Medial (internal) rotation: medial movement of the humerus around its longitudinal axis Glenohumeral movements • Horizontal flexion (adduction): anterior movement of the distal humerus in a horizontal plane, after placement of the humerus in 90 degrees of abduction • Horizontal extension (abduction): return from horizontal adduction. May also include posterior movement of the distal humerus in horizontal plane Corresponding movements Glenohumeral movement Scapulothoracic movement Flexion Upward rotation, abduction Extension Downward rotation, adduction Abduction Upward rotation Adduction Downward rotation Lateral rotation Adduction Medial rotation Abduction Horizontal flexion Abduction Horizontal extension Adduction Scapulothoracic action/muscles Upward rotation Upper and lower trapezius, serratus anterior Downward rotation Pectoralis minor, rhomboids Glenohumeral action/muscles Flexion Pectoralis major, anterior deltoid, coracobrachialis, biceps brachii Extension Latissimus dorsi, teres major, triceps long head, posterior deltoid Abduction Deltoid, supraspinatus, biceps brachii Glenohumeral action/muscles Adduction Pectoralis major, latissimus dorsi, teres major, triceps long head, posterior deltoid External rotation Infraspinatus, teres minor, posterior deltoid Internal rotation Subscapularis, teres major, pectoralis major, latissimus dorsi, anterior deltoid WE DO!! • Motor control for manual prostheses • Control cable excursion for manually operated componentry • Myoelectric control for myoelectric prostheses • Myoelectric signal processing from remaining muscles to electrically operated componentry Myoelectric signal acquisition, manipulation, and output tt ill eo.
