Exam 2: Kines Chap 7 Flashcards
What does AROM stand for?
Active Range of Motion(176)
What makes up the shoulder complex?
GH joint, scapula, clavicle, humerus(176)
What does the shoulder complex control?
placement of the hand in its occupational space(177)
True/FalseThe humerus moves in synchronization with the scapula at the GH joint
True(177)
What are the 6 motions of the scapula?
elevation, depression, retraction, protraction, internal rotation, external rotation(177)
Are these all the motions of the GH joint?Flexion, Extention, adduction, abduction, horizontal adduction, horizontal abduction
No; there is also internal and external rotation(177)
What term describes the movement relationship between the scapula in the shoulder girdle and the GH joint?
Scapulohumeral rhythm(180)
T/FScapulohumeral rhythm is described as a synchronization of combined movements that occur between the scapula and humerus during GH joint flexion and abduction.
True(180)
How many degrees of GH joint flexor abduction is known as the “setting phase”?
first 30 degrees(182)
What is the 2:1 ratio?
The second phase where the scapula rotates abducts and upward 1 degree for every 2 degrees of the GH joint flexion and abduction.(182)
What is the 2:1 ratio a measurement of?
scapulohumeral rhythm(182)
Is the 2:1 ratio consistent in the final phase of scapulohumeral rhythm?
No; in the final phase the scapula moves more then the GH joint(182-3)
Muscles that work together or in unison are…
synergists(183)
Muscles that work against each other to equal or cancel out movement….
antagonist(183)
What is a force couple?
Muscles that act together to provide a stronger functional movement(183)
What are the 2 requirements of a force couple?
1- movement must be rotary in nature2- line of force and pull of angle of all muscles must be in opposing directions
How many parts make up the trapezius?
3upper, middle, lower
How many parts make up the deltoid?
3anterior, middle, posterior
What is another name for Primary Adhesive Capsulitis?
“Frozen Shoulder”(186)
What are the 3 stages of frozen shoulder?
1- painful stage2- stiffening stage3- thawing stage
What is hemiplegia?
paralysis of one side of the body after a cerebrovascular accident (CVA) or stroke
This is a partial dislocation of the humerus at the GH joint.
Shoulder Sublaxation(think of Bobbie sticking her thumb in Clyde’s shoulder)
What is Erb’s Palsy?
injury to a baby’s brachial plexus and can cause weakness or paralysis of the arm
What is the rotator cuff?
a tendon covering the head of the humerus
Supraspinatus, Infraspinatus, the Teres major, and the Subscapularis are what?
The 4 muscles connected by the rotator cuff(acronym SITS)
T/FThe purpose of the rotator cuff is to lower and rotate the humerus.
False, it is to lift and rotate the humerus
What can an impingement cause?
local swelling and soreness
What are the 3 types of acromion shapes?
flat, curved, hooked
What is it called when the inferior angle of the scapula sticks out from the body?
winging of the scapula
What plays a role in joint movement?
Tendon
What provides stability for the skeletal system?
Ligament
What is the strongest external rotator of the shoulder complex and second most common injury?
infraspinatus
What is the largest muscle of the rotator cuff muscle?
subscapularis
Show me………………scapular elevation
Show me…………scapular depression
Show me…………scapular retraction
Show me………….scapular protraction
Show me……scapular upward rotation
Show me……..shoulder (GH joint) flexion
Show me……shoulder (GH joint) extension (also called hyperextension)
Show me GH joint Adduction

Show me the moro reflex
What is this?
Shoulder impingement
Name the rotator cuff muscles
Supraspinatus
Infraspinatus
Teres Minor
Subscapularis
What are the acromion types?
Show me winging of the scapula
Show me the empty can exercise
If no muscle contraction can be felt or seen a muscle grade of what is given?
O
If mm contraction can be felt, but there is no motion, a muscle grade of what is given?
1 Trace
If a part moves through complete ROM against gravity a mm. grade of what is given?
3 Fair
If a part moves through complete ROM against gravity and moderate resistance is given a mm. grade of what is given?
4 GOOD
If a part moves through complete ROM against gravity and full resistance a mm. grade of what is given?
5 Normal
