PD3 Flashcards
flexion
bending motion that decreases angle between 2 body parts
ABduction
motion that pulls a structure or part AWAY from midline
extension
bending motion that increases the angle between 2 body parts
ADduction
motion that brings a structure or part to/ACCROSS midline
hyperextension
added movement (extension) beyond the normal limit
internal rotation
rotation TOWARDS the axis of body
rotation
rotating, turning action of body part from another, internal or external
external rotation
rotation AWAY from axis of body
lateral bending
re spine: standing tall and tilting side to side w torso
re neck: ear to shoulder (not rotation, just tilting)
inversion
rotation inward, medially (most common method of sprained ankle.. sole of foot tilted IN)
supination
rotation that is turned outwards - laterally - holding a bowl of soUP
eversion
rotation outwards, laterally, sole of foot is tilted OUT
pronation
rotation that is turned inwards - toward medial line
plantar flexion
toes pointed away from shin
radial deviation
hands in neutral (flat) position and turned in towards thumb
ulnar deviation
hands in neutral (flat) and turned out towards pinky
dorsiflexion
toes brought up towards shin
grading system used to classify muscle strength
0-5, 5/5 is normal
supplies needed for exam of musculoskeletal system
skin marking pen
goniometer
tape measure
reflex hammer
myopathy
any congenital or acquired muscle disease, marked clinically by focal or diffuse musc weakness
neuropathy
any nerve disease or injury that affects a single nerve
polyneuropathy
any disease that affects multiple peripheral nerves
sprain
trauma to ligaments
strain
trauma to muscles & tendons from violent contraction or excessive/forcible stretch
dislocation
displacement of a bone from its normal position in a joint
subluxation
a partial or incomplete dislocation
additional body systems to evaluate during musculoskeletal exam
skin/soft tissues
surrounding joints
neurologic
shoulder joint
most potentially unstable of all major joints.
complex of 4 joints
4 joints that make up the shoulder
acromioclavicular
glenohumoral
thoraco-scapular
sternoclavicular
elbow joint
serves as link between powerful movements of shoulder and fine motor control of hand
wrist
required for most ADLs. injuries here can affect gross and fine motor movements
hands & fingers
required for most ADLs. injuries can greatly affect cross and fine motor movements

Sequence of exam techniques for upper extrem
- history
- inspection
- palpation
- functional assessment (ROM, musc strength)
- neuro
scapular winging
w/ abduction of arm, an outward prominence of the scapula indicates injury to the nerve of the anterior serratus muscle
drop arm test
w/ pt standing or sitting, a fully abducted shoulder is slowly lowered to the side. if there are rotator cuff tears (esp in supraspinatus muscle), the arm will fall uncontrollably to the side from 90 degrees
Yergason test
used to determine the stability of the long head of biceps tendon in the bicipital groove. have pt flex elbow, hold the flexed elbow w/ one hand while holding the pts wrist w/ other hand, internally rotate the arm and pull down on elbow at the same time. if biceps tendon is unstable in the groove, it will pop out and cause pain
apprehension test
for chronic shoulder dislocation. abduct and externally rotate pts arm to a position where it would easily dislocate. if the shoulder is ready to dislocate, the pt will have a look of apprehension or pain
tennis elbow test (lateral epicondylitis)
to reproduce pain of tennis elbow, stabilize pts forearm while they make a fist and they extend their wrist. apply pressure w/ your other hand to the dorsum of fist to force pts hand into flexion, which will cause pain at the lateral epicondyle
Tinnel sign - elbow
to elicit tenderness over a neuroma w/in a nerve. tap the area in the ulnar groove between the olecranon and the medial epicondyle. if neuroma is present, will cause tingling sensation down forearm.
Tinnel sign - wrist
tap pts wrist where the median nerve passes under the flexor retinaculum. if a tingling sensation radiates from the wrist into the hand, this is positive and indicative of carpal tunnel syndrome
allen test
to determine whether radial & ulnar arteries are supplying adequate amount of blood to hands. Have patient open/close hand into fist several times, then with the hand in a fist, occlude both radial and ulnar arteries. Patient then opens hand (which should appear pale), release ONE of the arteries while still occluding the other. The hand should flush immediately, if it doesn’t, this is an indication of a problem with that artery. Repeat testing the opposite artery and then the opposite hand as well.
Finkelstein test
to test for DeQuervain’s disease, where inflammation of the synovial lining of tunnel 1 in wrist narrows the tunnel opening and results in pain when the tendons move. Have patient make a fist with thumb tucked inside the other fingers. Stabilize their forearm with one hand, and use the other to deviate their wrist to the ulnar side. If sharp pain is felt in the area of tunnel 1, indicates stenosing tenosynovitis (DeQuervain’s disease).
Phalen test
to test for carpal tunnel syndrome, have patient flex wrists to maximum degree and hold for at least 1 minute. If tingling of fingers occurs, positive test.
