allen's test procedure

patient is in a seated position with forearms resting on thighs, palms up. patient opens and closes the hands 5 times and maintaining a tight fist after 5. doctor occludes radial and ulnar artery just proximal to the wrist, patient opens up hand, then doctor lets one artery go at a time. watch color come back to hands


allen's test purpose

test patency of the upper extremity arterial system


function of allen's test

occlude vascular flow to the hand in order to observe the filling time required by each vessel


findings of allen's test

delayed color return indicates partial blockage
no color return= complete blockage of artery


adson's test procedure

patient seated
doctor palpates radial pulse. maintain palpation while slightly abducting and externally rotating the patient's arm
patient rotates head to side being tested
extend the neck as far as possible
take a deep breath and hold for 10 seconds


purpose of adson's test

test for neurovascular compression of subclavian artery and/or brachial plexus


function of adson's test

hypertrophy of scalenus anticus or a cervical rib


findings of adson's test

positive if there is paresthesia or a decrease in amplitude of the radial pulse


modified adson's test

doctor palpates the radial pulse, doctor slightly abducts and externally rotates patient's arm
patient turns head away from tested area, extend back and hold breath for 10 seconds


purpose of modified adson's

test for neurovascular compression of subclavian artery or brachial plexus


function of modified adson's

test for hypertrophy of scalenus medius or cervical rib


findings of modified adson's

positive if there is paresthesia or a decrease in amplitude of the radial pulse


halstead's test procedure

patient seated, arms at side doctor palpates radial pulse
maintain palpation while pulling downward on affe ted arm while patient hyperextends the neck
hold breath for 10 seconds


purpose of halstead's test

neurovascular compression of subclavian artery and brachial plexus


function of halstead's test

scalenus medius muscle hypertrophy or cervical rib


findings of halstead's test

positive if paresthesia or decrease in amplitude of radial pulse


allen's maneuver procedure

doctor abducts shoulder 90 degrees and flexes patient's elbow for 90 degrees then shoulder is externally rotated
palpate radial pulse


clinical indication of allen's maneuver

disappearance of pulse indicates a positive test result for TOS


roo's test/hands up test/hostage test procedure

patient's arms are elevated 90 degrees and elbows are flexes 90 degrees, shoulders externally rotated
patient closes fists for 3 minutes


roo's test/hands up test/hostage test

stresses TOS


findings of roo's/hands up/hostage test

tingling or paresthesia in forearm and hand


wright's test/hyperabduction test procedure

patient seated with arms at side. doctor stands to side or behind favoring the side being tested. doctor palpates radial pulse, arm is abducted 180 degrees passively, note how long it takes for radial pulse to disappear. do both sides


function of wright's test/hyperabduction test

compresses axillary artery under pectoralis muscle


findings of wright's/hyperabduction test

if one arm's pulse goes away faster than the other, then it is positive


costoclavicular/eden's test procedure

patient in seated position with arms resting on thighs and palms facing up
palpate radial pulse, patient actively draws shoulders down and back, chin to ches and hold breath for 10 seconds


purpose of costoclavicular/eden's test

narrow space bewteen the clavicae and the first rib, thus compressing the neurovascular tissues of the sublclavian artery, vein and brachial plexus


function of costoclavicular/eden's test

narrowing could be caused by...
poor posture
cervical rib
bone tumor
poorly united fracture of the clavicle


findings of costoclavicular/eden's test

cessation or dampening of radial pulse
ischemic color changes
radicular pain in upper limb
