Warning Signs of Shoulder Injuries Is your shoulder stiff? Can you rotate arm normally? Does shoulder feel dislocated? Do you lack strength?
Shoulder Anatomy Clavicle Acromion Bones: Coracoid Process Humerus Scapula Glenoid Cavity
Shoulder Anatomy Muscles (Rotator Cuff) Subscapularis Supraspinatous Infraspinatous Teres Minor Anterior View Posterior View
Functions of shoulder muscles Supraspinatus • Abduction of arm at shoulder joint • Agonist muscle moving first 10-15 degrees • Stabilizes head of humerus to shoulder joint
Functions of shoulder muscles Infraspinatus • Stabilizes humerus • Extension • Medial rotation of arm • Abduction
Functions of shoulder muscles Teres Minor • Stabilizes humerus to shoulder joint • Externally rotates shoulder joint • Adduction • Extension
Functions of shoulder muscles Subscapularis • Medial rotation • Stabilizes humerus to shoulder joint • Depresses humerus head allowing it to move freely • Rotate arm towards body • Prevents displacement of humerus
Common shoulder injury occurrences Frequently caused by athletic activities which involve excessive, repetitive, overhead motions such as: • swimming • tennis • baseball • weightlifting
Other shoulder injury occurrences Can also occur during everyday activities such as: • Washing walls • Hanging curtains • Gardening
Types of injuries • Sprain – injury in joint due to stretching beyond its own capacity, tearing the fibers of the ligaments • Dislocation – joint seperation of humerus and glenoid cavity • Bursitis – chronic inflamation • Fracture – break in the continuity of the bone • Caused by • Falling on outstretched arm • Falling on tip of shoulder • Direct impact • Trauma • Overuse
Pulldowns 1. Place band above head to pull down at 45 degrees 3. Hold for 2 seconds, squeezing shoulder blades 4. Slowly return band to starting position 2. Pull bands down to sides 6 inches away from body with arms straight
Standing Rows 1. Place bands mid-height, pulling in a straight line 2. Pull bands towards chest contracting shoulder blades and bending elbows at 90 degrees. 3. Hold position for 2 seconds, then return to starting position
External Rotation 3. Slowly rotate shoulder out, keeping elbow bent at your side, rotating as far out as possible. 1. Place band mid height so you are pulling in a straight line 2. Place elbow at side, bent at 90 degrees with arm beginning across body 4. Hold position for 2 seconds, slowly returning to starting position.
Internal Rotation 1. Place band at mid height so you are pulling at a straight line. 3. Slowly rotate shoulder in, keeping elbow bent and at your side, rotating in as far as you can. 2. Place elbow at side, bent at 90 degrees holding arm away from body 4. Hold position for 2 seconds and slowly return to starting position.
Bicep Curl 1. Stand on band securing to ground with both hands at sides. 3. Hold for 2 seconds and return to starting position. 2. Bend at elbows up towards shoulders while flexing bicep
Tricep Press 1. Standing or kneeling, place band about waist high 3. Extend elbow against resistance until you reach full extension 2. Hold bands with elbows bent to your side at a 90 degree angle 4. Hold position for 2 seconds then slowly return to starting poistion
Arm extension 1. Secure band under feet or behind body. 3. Raise arms out in front creating a 90 degree angle, keeping elbows locked straight 2. Holding band keep arms straight down at your sides 4. Hold for 2 seconds then return to start position
Frequency of exercises • 5 days/week • 1-2 times per day • Start with 1 set of 15 repetitions, progressing a set every couple of days
CAUTION! If any exercises increase pain, stop immediately and report to a physician
