Athletic Training Test 6

Which test is used for glenohumeral joint instability?

apprehension test

What mechanism of injury is associated with rotator cuff sprain/tear?

acute trauma or impingement

What is the common mechanism for an acute injury to the upper extremity?

falling on an outstretched hand

What is the cause of shoulder impingement syndrome?

repetitive extrinsic movement of rotator cuff leads to compression of supraspinatus tendon, subacromial bursa, or long head of biceps tendon

What is the most common glenohumeral joint dislocation? How does it occur?

anterior glenohumeral discomfort (specifically subcoracoid), abduction, external rotation, or extension that forces the humeral head out of the glenoid cavity

How is impingement managed conservatively?

use POLICE intially to manage pain, strengthen rotator cuff muscles, stretch posterior/inferior joint capsule, correct posture

Which three bones comprise the shoulder joint?

clavicle, scapula, humerus

What signs and symptoms will be present in an anterior glenohumeral dislocation?

flattened deltoid contour, prominence of humeral head, moderate to severe pain and disability, unable to touch other shoulder with affected hand

What signs and symptoms of a fractured clavicle?

clavicule appears lower than unaffected side, swelling, point tenderness, mild deformity, tilts chin towards unaffected side

What is the immediate care for an acromioclavicular sprain?

application of cold and compression, stabilize shoulder joint with immobilizer, refer to physician for diagnosis and treatment

List the 4 muscles of the rotator cuff and their functions

subscapularis: medial rotation,

supraspinatus: abduction,

infrapsinatus: lateral rotation,

teres minor: extension, lateral rotation, shoulder horizontal abduction

List the 4 main articulations of the shoulder complex

sternoclabicular, acromioclavicular (AC), glenohumeral, scapulothoracic

List the signs and symptoms of shoulder bursitis

positive impingement test, pain with movement (especially in add/abduction, flexion, internal rotation), tenderness with palpation under the acromion

What are the 5 phases of throwing?

wind up, cocking, acceleration, deceleration, follow through

Describe the signs associated with grade 1, 2, and 3 AC joint sprains?

1: point tenderness, discomfort with movement, no deformity, no tear;

2: point tenderness, unable to fully abduct through full ROM, tear or rupture;

3: gross deformity, severe pain, loss of movement, instability, full rupture

How can you prevent shoulder injuries?

using correct throwing technique, ensuring proper physical conditioning (strengthening rotator cuff and scapular muscles), proper warm up, educating athlete how to fall correctly
