FUN FACTS
This is the only rotator cuff muscle that doesn't actually rotate the shoulder.
Supraspinatus
Which muscle does not originate on the scapula?
A. Rhomboids
B. Supraspinatus
C. Infraspinatus
D. Triceps Brachii
A. Rhomboids
During a client's evaluation the LMT observes that the client has bilaterally internally rotated glenohumeral joints. Upon palpation the subscapularis found to be short, tight, and contains trigger points. Which muscle is most likely to be inhibited?
INFRASPINATUS
If a client has pain in the acromial region, which joint is most likely involved?
A. Elbow
B. Hip
C. Knee
D. Shoulder
D. Shoulder
It is more common in woman and likely to affect both shoulders, however not simultaneously.
Frozen Shoulder
These three bones make the shoulder joint/complex.
Clavicle, scapula, and humerus
These four muscles compose the rotator cuff group
Supraspinatus
Infraspinatus
Teres Minor
Subscapularis
This muscle is called "Lats little helper" because it is synergistic.
Teres major
The glenohumeral joint is a good example of which of the following statements?
A. When mobility increases, stability increases.
B. When stability is less, mobility is also less.
C. As mobility increases, stability decreases.
D. Mobility is supported before stability is attained.
C. As mobility increases, stability decreases.
What movement of the shoulder involves bringing the arm away from the midline in the coronal plane?
Abduction
In which muscle are you more apt to find trigger points for a client that presents with a frozen shoulder?
Subscapularis
The scapula is an attachment for how many muscles?
A. 13
B. 12
C. 8
D. 16
D. 16
WHAT ARE THEY?
True or false:
The scapulothoracic joint is not a true joint but plays an important role in full shoulder elevation.
TRUE
A person carrying a heavy bucket with one hand for an extended period of time may experience pain or tenderness in which rotator cuff muscle?
Supraspinatus
The antagonist to the subscapularis
Infraspinatus
These two muscles will fuse together as they are adjacent and synergistic in external rotation of the shoulder. What are these two muscles?
Infraspinatus and teres minor
Which of the following is a hallmark of frozen shoulder?
A. Only PROM is affected
B. Only AROM is affected
C. Both AROM and PROM are limited
D. Severe pain with any movement but full range of motion
C. Both AROM and PROM are limited
What muscle is the primary mover for shoulder abduction from 0-15 degress?
Supraspinatus
Which muscle attaches at the medical border of the scapula?
A. Latissimus dorsi
B. Trapezius
C. Coracobrachialis
D. Serratus anterior
D. Serratus anterior
The latissimus dorsi performs extension of the shoulder primarily. What other actions does it perform?
What are the functions of the posterior deltoid muscle and the insertion?
Extension and external/lateral rotation; Deltoid tuberosity
A patient with a rotator cuff tear typically reports which of the following symptoms?
A. Severe stiffness with no weakness
B. Sharp, stabbing pain over the anterior shoulder
C. Difficulty lifting the arm overhead, pain at night, and weakness
D. Numbness radiating to the hand
C. Difficulty lifting the arm overhead, pain at night, and weakness
Assessment indicates that the left scapular area is rounded forward and protracted. What muscle pair is likely to be short and tight?
A. Trapezius and rhomboid minor
B. Levator scapulae and supraspinatus
C. Pectoralis minor and serratus anterior
D. Teres minor and infraspintus
C. Pectoralis minor and serratus anterior
A client details on an intake form that they work at a desk all day and use a computer the majority of the time. The LMT performs a visual assessment and determines the client's shoulders both appear to be elevated. Which of the following WOULD NOT likely be a contributing factor to the client's overly-elevated scapulae?
A. Weakness of the latissimus dorsi muscle
B. Hypertonicity of the levator scapulae muscles
C. Weakness of the serratus anterior muscles
D. Hypertonicity of the upper fibers of the trapezius
A. Weakness of the latissimus dorsi muscle
True or False:
The teres major inserts onto the greater tubercle of the humerus.
FALSE
The teres major inserts on the intertubercular groove of the humerus.
The primary function of the shoulder girdle muscles that have attachments at the axial skeleton, the scapula, and the clavicle is....
A. Extension of the shoulder joint
B. Stability of the scapula
C. Mobility of the humerus
D. Mobility of the glenohumeral joint.
B. Stability of the scapula
A client with a torn rotator cuff presents to you and asks if muscle scrapping (gua sha) would be beneficial. How would you respond?
Gua sha would be indicated as it allows micro tears to form in the tissue which allows the LMT to help appropriately lay down fibroblasts to lay down scar tissue appropriately. Gua sha will also bringing in fresh, nutrient rich blood to help repair the tissue.
