1Name Lab Section Analysis of Shoulder Girdle MovementsPurpose: To develop a knowledge and understanding of movements of the shoulder girdle, the role that the various muscles play in these movements, and shoulder girdle accommodation of fundamental movements of the upper extremity.Equipment: TextbookProcedures to be completed prior to the lab session:1. Review actions for the shoulder girdle and shoulder joint muscles.2. Supply the movement terminology that fits the following definitions for shoulder girdlemovements: the scapulae move laterally away from the vertebrae with the vertebral borders remaining approximately parallel to the vertebrae the glenoid fossa faces upward and the inferior angle moves laterally the scapulae move upward, the vertebral borders remain approximately parallel to the vertebrae the inferior angles of the scapulae pull away from the ribs, the posterior surfaces face slightly upward, and the inferior angles protrude from the back3. What are the primary functions of the shoulder girdle?24. The shoulder girdle movements are in accommodation of, or as stabilizers for, movements of the arm at the shoulder joint. Match the shoulder girdle actions with the shoulder joint actions that they accommodate.SHOULDER JOINT ACTIONS SHOULDER GIRDLE ACTIONS abduction a. elevation flexion > 90 degrees b. depression hyperextension c. upward rotation horizontal adduction d. upward tilt horizontal abduction e. protraction (abduction)f. retraction (adduction)3Procedures to be completed during the lab session:1. Select a lab partner and complete the exercises.2. The key to determining the action of the shoulder joint is to carefully watch the effect of the movement on the elbow's position - if the elbow moves forward, flexion is occurring, etc. The key to determining the action of the shoulder girdle is to watch the lateral and inferior angles of the scapulae during the movement.Place your fingers on your lab partner's scapulae as he/she performs the following movements. Determine the action that is occurring during the concentric phase of muscle contraction at the shoulder girdle and shoulder joint. Write down the correct term that describes this movement.What are the training and rehabilitation implications for doing these analyses?Exercise PositionShoulder GirdleMotionShoulder JointMotionPush-upWide hand placementNarrow hand placementOverhead pressIn front of headBehind headSeated rowNarrow gripWide gripLat pull downNarrow gripWide grip45. Perform three (3) of the following sports skills or training exercises for your lab partner. For each, complete the chart on the following page. Identify the shoulder joint action thatoccurs on the preferred side during the execution phase of the skill and check the muscles that cause this shoulder joint action. Finally, identify the accompanying shoulder girdle action that accommodates this movement at the shoulder joint and check the the muscles that cause this shoulder girdle action to occur. a. underhand volleyball serve e. baseball swingb. crawl stroke arm recovery f. standing long jump takeoffc. tennis serve g. shot putd. lateral dumbbell shoulder raise5Skill:Joint ActionUT MT LT LS RH PMn SAPMj(S)PMj(C)LD AD MD PD CBTMnTMr IS SSp SSc TB BBShoulder JointFlexionExtenAbductAdductMRotLRotHAddHAbdShoulder GirdleProtRetElevDepUpRotDnRot6Skill:Joint ActionUT MT LT LS RH PMn SAPMj(S)PMj(C)LD AD MD PD CBTMnTMr IS SSp SSc TB BBShoulder JointFlexionExtenAbductAdductMRotLRotHAddHAbdShoulder GirdleProtRetElevDepUpRotDnRot7Skill: Joint ActionUT MT LT LS RH PMn SAPMj(S)PMj(C)LD AD MD PD CBTMnTMr IS SSp SSc TB BBShoulder JointFlexionExtenAbductAdductMRotLRotHAddHAbdShoulder GirdleProtRetElevDepUpRotDnRot8SCAPULA STABILIZATIONWhen the arms are used to push or pull objects, the scapula must be stabilized in order to provide afirm base from which the arms can push or pull. For the examples 1-5, answer the followingquestions:A. Identify the action of the object (that is underlined) on the scapula. Your answer should be one of the following: elevation, depression, abduction, or adduction.B. Identify the functional muscle group that must be contracted to offset the action of the object on the scapula (i.e., to stabilize the scapula).C. List the specific muscles that belong to the group you identified in B.1. Vertical push upward. Hold a heavy book over your shoulder as you would hold a tray.A. B. C. 2. Vertical pull upward. Stand and hold a suitcase, briefcase, or other similar object in one hand.A. B. C. 3. Vertical pull downward. Sit on the floor with your legs extended under a table. Grasp the edge of the table top with both hands. Pull down on the edge of the table top to simulate a pull-up. Your partner should sit on the opposite side of the table to prevent tipping.A. B. C. 4. Horizontal push forward. Stand facing a wall and at an arm's length away. Flex the shoulder to 90 degrees and place the hand on the wall. Push against the wall.A. B.
