Ortho NEED TO KNOW Flashcards
(127 cards)
What is part vs. whole practice?
Practice of an individual component versus practice of an entire task
Intrinsic (Inherent) Feedback
all feedback that comes through the sensory systems including visual, vestibular, proprioceptive, and somatosensory input
Extrinsic (augmented) feedback
information provided while a task or movement in in progress or subsequent to the movement
Usually verbal feedback or manual contacts
Sternoclavicular Joint
3 degrees of freedom
Elevation Depression
Protraction Retraction
Rotation
What does the subclavius muscle do?
depresses clavicle and stabilizes it
Which ligament does the clavicle use as a pivot point in elevation of the distal clavicle?
Costoclavicular Ligament
Acromioclavicular Joint consists of…
distal clavicle and acromion process of the scapula
What are the motions of the AC joint?
Elevation Depression
Retraction Protraction
Rotation
What is the Scapulothoracic Joint
Not a true joint
but is a functional joint
DIRECT RESULT OF MOTION WITHIN THE AC AND SC JOINTS
Contributes 1/3 of elevation in scapulohumeral rhythm
Elevation Depression
Protraction Retraction
Scap Upward Downward Rotation
What is winging?
Internal rotation of the shoulder
What is tilting
Anterior or Posterior
Most common impairment is anterior tilting
What 3 ligaments support the GH joint?
(Anteriorly, Intrascapular)
Superior
Middle
Inferior GH ligaments
Which ligament combats the pull of gravity in the GH joint?
Coracohumeral Ligament
Which ligament holds the long head of the bicep tendon on to the bicipital grove?
Transverse Humeral Ligament
What does the clavicle do when the scapula elevates (shrugging, flexion, or abducting)
the distal clavicle elevates
proximal clavicle rolls superiorly and glides inferiorly on the sternum
pivoting the costoclavicular ligament
When UE goes into flexion what does the clavicle do?
must rotate posteriorly to achieve full elevation
What muscles work as a team to rotate, elevate depress, and protract retract the scapula?
Traps, Levator Scap, Rhomboids, Serratus Anterior, Pec Minor
What nerve innervates Serratus Anterior
Long Thoracic Nerve
What happens if Serratus Anterior is weak
Can cause winging of the scapula
Excessive Anterior tipping is cause by what?
tightness of pec MINOR
(sometimes short head of biceps and coracobrachialis)
or
Weakness of SA and/or lower trap
What are the extensors of the GH joint?
Posterior Delt (axillary n)
Lats (thoracodorsal n)
teres major (subscap n)
What are the flexors of the GH joint
Anterior Delt (Axillary n)
Coracobrachialis ( Musculotaneous n)
What are the Abductors of the GH joint?
Middle Delt (axillary)
Supraspinatus (suprascapular n)
What is the function of the Rotator Cuff?
- Create rotation at the joint
- increase compressive forces between humeral head and socket
- Fascilitate gliding while humeral head rolls in the opposite direction
