Can use additional straps/ wall to add deeper stretch 6  PTA 1010 Week 6 lab- The shoulder Girdle Shoulder flexors (elbow bent biases the joint and single joint muscles, elbow extended with pronation biases the biceps brachii) ISOMETRICS (pictured in neutral) Isometrics can be performed in different ranges of motion Submaximal isometrics used in the acute phase of healing Parameters: 1-3 sets, 20 x 5-10 Use a towel or ball and flex the elbow to 90°. Make a fist, position yourself and pictured below depending on the muscle action you are activating at the glenohumeral joint. Push the fist into the wall or towel, contracting the intended muscle group with no movement occurring Flexion Extension Abduction Internal Rotation External Rotation Adduction Section 2: Scapular stabilization & RTC/ Deltoid exercises Review/ Shoulder mechanics: Faulty posture significantly alters scapular kinematics During elevation of the arm, the humerus externally rotates for the greater tubercle of the humerus to clear the coracoacromial arch Deltoid-Short Rotator Cuff Mechanism: The deltoid and short rotators balance forces to elevate the humerus and control the humeral head. The Supraspinatus muscle stabilizes, compresses, and slightly translates the humerus upward 7  PTA 1010 Week 6 lab- The shoulder Girdle Preparing the patient for exercise: ✓ Sitting or standing with upright posture with T/S extended ✓ Abdominals should be actively pulling the rib cage in to allow a stable base to activate the retraction without extending the lumbar spine. ✓ Cervical retraction (to reduce forward head) to neutral must be performed before engaging global muscles- cue the patient to have the head raise up like a helium balloon ✓ Have the patient draw the scapula together in a slightly downward motion. Patient should not shrug the shoulders or elevate the shoulders towards the ears. ✓ When adding shoulder movement into elevation: do not focus on the scapula remaining in the fully retracted position as this will limit the needed rotation or protraction with lifting overhead. Exercise Management: Common compensations: Determine the targeted muscle Over activity of the upper fibers of trapezius Identify the healing phase Trunk movement compensations Let the patient know what they should expect to feel Movement out of external rotation Determine your goals: strength vs endurance Movement away from the body (use the towel roll) Look for substitutions Movement out of plane of motion: especially if in Looks for signs of fatigue allow for muscle recovery elevated abducted ranges Consider the effects of gravity Humerus may drift during shoulder IR/ER Contraction Type: concentric, eccentric or isometric Open kinetic chain vs closed kinetic chain Posture/Positioning Review of muscle activity and function Scapular Motions and Muscles Involved Upward & Downward rotation Retraction & protraction Elevation & Depression www.musculoskeletalkey.com www.musculoskeletalkey.com www.musculoskeletalkey.com Upward Rotation Downward rotation Retraction Protraction Elevation Depression Serratus anterior Rhomboid major Rhomboid major Serratus anterior Levator scapulae Lower trapezius Upper trapezius Rhomboid minor Rhomboid minor Upper trapezius Lower trapezius Levator scapulae Middle trapezius 8  PTA 1010 Week 6 lab- The shoulder Girdle HOW THE MUSCLES WORK TOGETHER: (www.earthslab.com) Lab activity #1 Review the concept of stretch weakness and practice isometrics in the shortened position. Addressing Stretch weakness 1. Muscles postured in a lengthened position for an extended period respond by adding sarcomeres in series, thus making it longer and unable to shorten fully to its original shortened position. This phenomenon is called stretch weakness 2. To strengthen stretch weakness, end range isometrics are performed in regular intervals to retrain the muscle to assume its original length Middle trapezius Lower Trapezius 9  PTA 1010 Week 6 lab- The shoulder Girdle Lie on your back on the floor in half kneeling Lie on your back on the floor in half kneeling Place your UE in 90/90 or a “touchdown pole” Place your UE in 130° abduction over the head or a position “diamond” position If you have limited shoulder ER, prop the If you have limited shoulder ER, prop the forearms forearms onto pillows, leaving the elbows on the onto pillows, with the elbows and wrists resting on the floor pillows Cue the patient to draw in the TrA and pull the Cue the patient to draw in the TrA and pull the lower lower ribs towards the pelvis ribs towards the pelvis Pushing the distal forearm (not the hands/wrists) Pushing the distal forearm (not the hands/wrists) back back into the floor for 10 seconds into the floor for 10 seconds Perform 10 sets of 10” Perform 10 sets of 10” Watch for excessive arching of the back or Watch for excessive arching of the back or elevating of elevating of the ribs the ribs Lab activity 2: Scapular Isolation Exercises- depression and retraction Learning a proper scapular retraction is important as the activation is key before moving into additional scapular strengthening exercises. It is important for the patient to be able to retract without scapular elevation, or overuse of the upper trapezius. Each person will respond differently to the different ways of activating these muscles. Find the way the patient responds best Arms across chest Arrested posture resisted Retraction prone with a weight Lie with the arm over the edge of the table with a weight Keep the arm straight (elbow exteded) hanging with gravity Raise the scapula and arm up towards the ceiling (keeping the arm straight) The motion is scapular retraction Ensure the scapula is not elevating towards the head during the movement 10  PTA 1010 Week 6 lab- The shoulder Girdle Lower Trapezius Ball Depression Start by standing alongside a hi/lo table with the table at a height where the extended arm just touches the ball when the patient is standing upright Instruct the patient to draw the scapula downwards and toward the CL buttock by pushing down into the ball with the extended arm Cue the patient to stabilize the trunk so there is no lateral trunk lean Hold 5-10 seconds isometrically (B) Scapular Depression with lat. bar Use both UE on a bar (lat. bar) and get into a kneeling position underneath the bar with the arms extended The position is like performing a lat. pull down, but the patient will keep the elbows extended as you depress the scapulae (B) at the angle noted in the photo Maintain the retracted/ depressed position for 5-10 seconds isometrically and release slowly out of the posture Cue the patient to draw the abdomen in (or ribs to belly) to avoid spinal extension in the position STRENGTHENING & STABILIZING EXERCISES: GH joint and Scapulothoracic joint Strength parameters: 1-3 sets of 8-12 reps, 3-4 days/wk Endurance parameters: 2-5 sets of 15-50 reps 3-5 days/ week Exercise description PROGRESSIONS & VARIATIONS Open Chain Serratus Punch Activates in 90° to 120° flexion While keeping your elbow straight, protract your shoulders forward towards the ceiling and then lower back down in a control motion.

Practice and instructor your lab partner on proper performance of the exercises below. Muscle activity of the rotator cuff and deltoid (From Reinold et al, JOSPT 2009): Supraspinatus: Increased muscle activation from 30°-60° into elevation The full can exercise is a better position than the empty can at isolating supraspinatus decreases shear force from middle and posterior deltoid Supraspinatus is highly active during standing forward scapular punch, rowing exercises, push-up exercises, 2 hand overhead medicine ball throws, prone horizontal ABD at 100° ABD + full ER, prone or standing full can. Subscapularis: The upper fibers are more active at lower angles of abduction Subscapularis is also active with IR at 0° abduction, and D2 diagonal PNF pattern flexion and extension exercise Infraspinatus: More effective/active in the lower shoulder abduction angles Teres Minor is unaffected by shoulder angle. Best position for Combined Teres Minor and Infraspinatus (external rotator) activation is: 1. Side-lying external rotation 2. Standing external rotation in 45° of abduction 3. Prone external rotation at 90° abduction Adding a towel roll between the brachium and side of the trunk showed increased muscle EMG by 20%-25% with ER. Deltoid: Anterior fibers: effective abductor at 0° Abd + 60° ER (Full can) Posterior fibers: high activity with prone full can position. 60° of abduction the deltoid causes instability (humeral head anterior translation) 60° of scaption the deltoid contributes to stability Middle deltoid contributes more towards abduction after 40° of abduction ROTATOR CUFF AND DELTOID STRENGTHENING Strengthening: 1-3 sets; 812 reps, 3-4 days/week Endurance: 2-5 sets; 15-50 reps, 3—5 days/week EXERCISE DUMBBELL/CONSTANT WEIGHT TUBING/ VARIABLE RESISTANCE Shoulder ER at 0 ° abd.
