MSK Flashcards
What is this movement
Flexion
What movement is this
Extension
What is this movement
ABDuction
“Raise your arms out to the side and overhead”
Whats this movement
ADDuction
“Cross your arm infront of your body”
What is this movement?
Internal rotation
“Place one hand behind your back and try to touch your shoulder blade”
What is this movement
External rotation
“Raise your arm to shoulder level; bend your elbow and rotate your forearm toward the ceiling”
What is this maneuver
Crossover or crossed body test
Adduct the patients arm across the chest (AC joint)
What is this maneuver
Apley scratch test (overall shoulder rotation)
Ask the patient to touch the opposite scapula using these 2 motions
Pain: could suggest rotator cuff disorder or adhesive capsulitis
What is this maneuver
Painful arc test
Fully ABDuct the patients arm from 0-180 degrees
If painful: suggestive of subacromial impingement syndrome/rotator cuff tendonitis)
What is this maneuver
Neer Impingement sign
Examiner presses on the patient’s scapula to prevent scapular motion with one hand, and raises the patients arm with the other hand.
+ test for a subacromial impingement syndrome/rotator cuff tendonitis disorder)
When both neer and hawkins tests are negative
Very LOW likelihood of rotator cuff disorder
What is this maneuver
Hawkins impingement
Flex the patients shoulder and elbow to 90 degrees with the palm facing down. Then with one hand on the forearm and one on the arm rotate the arm internally
+ sign for supraspinatus impingement syndrome/rotator cuff impingement
What is this maneuver
External rotation lag test
With the patients arm flexed to 90 degrees and palm up rotate the arm into full external rotation and ask the patient to keep their arm in this position
INABILITY TO MAINTAIN: positive test suggestive of tears to the supraspinatus and infraspinatus muscles/ shoulder impingement syndrome
Whats this maneuver
Internal rotation lag test (lift off test)
With you standing to the patients rear, bring the dorsum of the hand behind the low back with the elbow flexed to 90 degrees. Then grip the wrist and lift the hand off the back which further internally rotates the shoulder. Ask the patient to keep the hand in the position as you release the wrist.
Inability to maintain = + tests indicates subscapularis tendinopathy or torn muscle
What is this maneuver
Drop arm test
Ask the patient to fully Abduct the arm to the shoulder level up to 90 degrees and lower it slowly (after you release your hand)
The abduction above the shoulder level from 90-120 degrees reflects action of the deltoid muscle
+ sign: if they are unable to slowly lower the arm (itll just DROP)
This suggests supraspinatus rotator cuff tear or bicipital tendinitis
What is this maneuver
External rotation resistance test
Ask the patient to flex the arms to 90 degrees with the thumbs turned up. Stabilize the elbow with one hand and apply pressure to proximal to the patients wrist as the patient presses the wrist outward in external rotation.
+ if mobility is limited OR it illicits pain
Suggests infraspinatus disorder
Limited extension suggests glenohumeral disease or adhesive capsulitis
Whats this maneuver
Empty can test
Elevate the arms to 90 degrees and internally rotate the arms with the thumbs pointing down as if emptying a can. Ask the patient to resist as you place downward pressure on the arms.
+test: inability of the patient to hold the arm fully abducted at the shoulder or control lowering the arm
Suggests supraspinatus rotator cuff tear
NOT a stand alone test less specificity
What are the four key features for the MSK exam?
IPROMS
INSPECTION: evaluate visually for signs of deformity, swelling, scars, inflammation or atrophy
PALPATE: use surface anatomy landmarks to localize points of tenderness or fluid collection
Range of motion: have the patient actively move the involved joints, then passively move them as the examiner.
Special maneuvers: perform stress maneuvers (if indicated) to evaluate joint stability and the integrity of ligaments, tendons or bursae especially if pain or trauma is present.
Acute vs chronic joint pain
Acute: last from days to weeks
Chronic: lasts months to years
Whats a monarticular disease?
Pain localized to ONE joint
Ie, injury, monoarticular arthritis
What is a polyarticular disease
More than 4 joints
Ie. RA, systemic lupus and OA
What is crepitus? What does it indicate?
Crepitus is audible or palpable crunching during the movement of tendons or ligaments over bone or areas of cartilage loss.
What are the 4 cardinal signs of inflammation
Swelling
Warmth
Redness
Pain
Swelling
Palpable swelling may involve
1. Synovial membrane may feel boggy or doughy
2. Effusion from excess synovial fluid in the joint space
3. Soft tissue structures, such as bursae, tendons, and tendon sheaths
