Arc of motion attained by an examiner without assistance from the subject.
What is Passive Range of Motion (PROM)?
100
These motions of the scapula are mostly linear.
What are elevation/depression and protraction/retraction?
100
The fossa located on the anterior surface of the scapula.
What is the subscapular fossa?
100
A grooved wheel that turns on an axis with a rope or cable riding in the groove.
What is a pulley?
100
The class of levers found most commonly in the human body.
What are third class levers?
200
This is placed over the axis of motion of joint being measured.
What is the fulcrum?
200
This is the landmark of the scapula used to determine the direction the scapula is rotating.
What is the inferior angle?
200
The shoulder joint and accompanying shoulder girdle motions by putting your wallet in your left back pocket with your left hand.
What are hyperextension and medial rotation of shoulder joint and scapular tilt and protraction?
200
The balance point of an object at which torque on all sides is equal.
What is center of gravity (COG)?
200
Plays a part in stability. That part of the body that is in contact with the supporting surface.
What is base of support (BOS)?
300
With pt. in supine, fulcrum centered over lateral aspect of greater tubercle. Proximal arm parallel to midaxillary line of thorax. Distal arm aligned with midline of humerus.
What is measuring shoulder flexion?
300
The relationship between the shoulder girdle and shoulder joint where after the first 30 degrees, for every 2 degrees of shoulder flexion or abduction, the shoulder girdle rotates upwardly 1 degree.
What is scapulohumeral rhythm?
300
These muscles hold the head of the humerus in toward the glenoid fossa as it rotates in the socket.
What the rotator cuff muscles (SITS)?
300
All the force generated by the muscle is directed back into the joint, pulling the two bones together.
What is a stabilizing force?
300
A superficial fibrous sheet attaching to the spinous processes, the supraspinal ligament and the iliac crest.
What is the thoracolumbar fascia?
400
With pt in supine, the fulcrum is on the olecranon process, the proximal arm is perpendicular to the floor and the distal arm is aligned with the ulna
What is measuring shoulder medial rotation (internal rotation)?
400
Raising your hand over your head requires the combined action of these 3 shoulder girdle muscles.
What are the serratus anterior, the upper trapezius and the lower trapezius muscles?
400
These muscles are innervated by the axillary nerve from C5-C6.
What are the deltoid and teres minor muscles?
400
When two forces act in equal but opposite directions resulting in a turning effect.
What is a force couple?
400
Inflammation and fibrosis of the shoulder joint capsule leading to pain and decreased ROM is know as:
What is adhesive capsulitis or frozen shoulder?
500
Normal ROM for shoulder extension (hyperextension).
What is 50 - 60 degrees?
500
The muscles that attach to the posterior surface of the scapula.
What are the rhomboids, upper, middle and lower traps and levator scapula muscles?
500
An overuse condition involving compression between the acromial arch, humeral head and coracoacromial ligament
What is impingement syndrome?
500
This is determined by dividing the length of a force arm by the length of a resistance arm.
What is the mechanical advantage?
500
The shoulder girdle motion occurring with closing a window by pulling down.
What is downward rotation of scapula (and shoulder extension)?
