2
(continued )
• Joints are held together with ___________ and joint capsules that provide stability and allow for limited movement.
– Shoulder girdle and the ____ joint can move in almost every direction.
• ___ & SC joints are just under the skin and are vulnerable to injury, even in muscular athletes
• Major nerves are from a group called the brachial plexus.

•S.I.T.S. muscles

• Proper physical conditioning is key
• Develop body and specific regions relative to ________
• Strengthen through a full ________
– Focus on _____________ muscles in all planes of motion
– Be sure to incorporate scapula
_______________ muscles
•
Enhances base of function for glenohumeral joint
7
•Instruction in proper throwing mechanics is critical for injury prevention
8
• ___________ Phase
– First movement until ball leaves gloved hand
– Lead leg strides forward while both shoulders
________, externally rotate and horizontally abduct
• ________________
– Max external rotation until ball release (humerus adducts, horizontally adducts and internally rotates)
– Scapula elevates and abducts and rotates upward
9
• ____________________ Phase
– Ball release until max shoulder internal rotation
– Eccentric contraction of ext. rotators to decelerate humerus while rhomboids decelerate scapula
• __________________ Phase
– End of motion when athlete is in a balanced position
10

13
14
(continued)

17

22
23
(continued)
First Aid

24

• Rotator cuff muscles contribute to GH joint
_________ and _________.
• Errors in the execution of a throw or swing can contribute to overuse injury.
25
26
Signs and symptoms include:

• Difficulty bringing arm up and back during _______ phase of throw. Pain and stiffness in shoulder region
_________ hours after throwing or swinging.
• Point tenderness around region of the humeral head that seems to be deep in __________ muscle.
27
(continued)
First Aid
– First aid is NOT practical due to chronic nature of condition.
