Shoulder joint complex 1.​ Anatomic considerations -​ GLENOHUMERAL JOINT: -​ Enarthrodia joint -​ Humeral head + glenoid cavity -​ SCAPULOTHORACIC JOINT: -​ Fake joint -​ Subescapular + anterior serratus -​ ACROMIOCLAVICULAR JOINT: -​ Arthrodia -​ Clavicule + acromion -​ STERNOCOSTOCLAVICULAR JOINT: -​ Reciprocal engagement -​ Clavicule + manubrium + first rib -​ SUBACROMIAL OR SUBDELTOID JOINT: -​ Fake joint -​ Deltoid + supraspinatus 2.​ Range of motion -​ FLEXION: 180º -​ EXTENSION: 45º - 50º -​ ABDUCTION: 180º -​ ADDUCTION: 30º - 45º -​ INTERNAL ROTATION: 90º -​ EXTERNAL ROTATION 90º  3.​ Main shoulder muscles -​ BICEPS BRACHII: Shoulder flexion -​ TRAPEZIUS: Scapular rotation -​ MAJOR PECTORAL: Shoulder flexion, adduction and internal rotation -​ DELTOID: -​ Anterior: Shoulder flexion and internal rotation -​ Middle: shoulder abduction -​ Posterior: shoulder extension and external rotation -​ SUBSCAPULAR: Shoulder abduction and internal rotation -​ SUPRASPINATUS: Shoulder abduction and external rotation -​ INFRASPINATUS: Shoulder external rotation -​ TERES MAJOR: Shoulder extension, adduction and internal rotation -​ TERES MINUS: Shoulder adduction and external rotation. 4.​ Tests: BALL ABDUCTION EXTERNAL ROTATION: -​ Performance: -​ Keeping a 3 kg ball on the shoulder with the elbow flexed -​ Elbow extension until the shoulder is 90º abducted -​ Elbow flexion -​ Lift the ball above the head with the elbow extended -​ Outcome: number of repetitions during 1 minute -​ Clinical significance: weakness in the rotator cuff muscles DROP CATCHES: -​ Performance: -​ 90º of shoulder abduction and elbow flexion keeping a tennis ball -​ Drop the ball and try to catch it -​ Outcome: number of repetitions during 1 minute -​ Clinical significance: lack of reaction speed and/or limitation of internal rotation range of movement BALL TAPS: -​ Performance: -​ Fit ball on the wall at 180º of shoulder abduction -​ Bounce the ball off the wall up to 90º and come back -​ Outcome: number of repetitions during 1 minute -​ Clinical significance: lack of shoulder stability OVERHEAD SNATCHES: -​ Performance: performing squats while lifting a ball of 5 kg overhead and down -​ Outcome: number of repetitions in 1 minute -​ Clinical significance: lack of shoulder muscles strength PUSH-UP CLAPS: -​ Performance: performing a explosive jumping push-up -​ Outcome: number of repetitions in 1 minute -​ Clinical significance: lack of stability and lack of strength LINE HOPS: -​ Performance: -​ Push-up with knee support position and one hand in the floor -​ Try to jump between right and left sides with the hand -​ Outcome: number of repetitions during 1 minute -​ Clinical significance: lack of mobility and lack of stability SIDE HOLD ROTATION: -​ Performance: -​ Side plank position and try to rotate the trunk -​ Touch the hand supported with the other hand and come back -​ Outcome: number of repetitions during 1 minute -​ Clinical significance: lack of mobility and lack of stability MODIFIED CLOSED KINETIC CHAIN UPPER EXTREMITY STABILITY TEST (MCKUES): -​ Performance: -​ Push-up position with the hands separated by 90 cm -​ Try to touch left hand with the right hand and inversely -​ Outcome: number of repetitions during 1 minute -​ Clinical significance: lack of stability
