standard assessments for hand impairments Flashcards
Standardized vs non-standardized
standardized strengths-
- quantitative research- help validate findings
- follow up tests are consistent
- specific directions increase reliability
weaknesses-
- not adaptable
- standardized on a limited population
- reading directions (unnatural)
reliability
measure of consistency
Inter-rater reliabilty
assesses the degree of agreement between two or more raters in their appraisals
Test-retest reliability
Assesses the degree to which test scores are consistent from one test admin. to the next. Measurements are gathered from a single rater who uses the same methods or instruments and the same testing conditions.
Validity
A test can be reliable without being valid.
How accurately a test measures what it claims to measure
sensitivity
ability of the test to accurately measure the presence of a condition
Specificity
ability of a test to accurately identify the absence of a condition
standardized tests
procedures are the same very time it is given
Purdue peg board
5 separate scores (subtests)
- right hand
- left hand
- both hands
- right plus left plus both hands
- assembly
aid in the selection of employees for jobs that require fine and gross motor dexterity and coordination. It measures gross movements of hands, fingers, and arms and fingertip dexterity as necessary in assembly tasks.
purpose- fine motor dexterity, grasp and release, gross motor, and manipulation
timed
Minnesota Rate of Manipulation Test (MRMT)
tests eye hand coordination and motor abilities. more of gross motor and grasp
purpose- measures the speed of gross arm and hand movements during rapid eye-hand coordination tasks.
-dexterity, grasp and release, manipulation
there are different versions. one is shorter than others to decrease fatigue factor
5 subtests
- placing
- turning
- displacing
- one-hand turning and placing
- two hand turning and placing
should be done with the patient standing
report the time it took to complete task
Jebsen Test of hand function
composed of seven subtests that represent carious hand activities and is an occupation based assessment
-both right and left hands tested with the nondominant first.
purpose- assess ADLs, dexterity, grasp and release, manipulation and strength.
fine motor, weighted and non-weighted hand function is assessed through
- writing
- turning over 3 by 5 inch cards
- picking up small common objects
- simulated feeding
- stacking checkers
- picking up large objects
- picking up large heavy objects.
Nine hole peg test
place 9 pegs into 9 holes
-test is timed and patient performance is compared with normative data.
purpose- grasp and release, manipulation.
Box and blocks
functional test to measure the patients performance in grasping medium sized blocks
purpose- grasp and release, manipulation.
O’Connor tweezer dexterity test
tweezers or clamps to work on fine motor activities- takes a while and can be very fatiguing.
finger- successfully used as a predictor for skills involving rapid manipulation of small objects. grasp and release, manipulation.
tweezer- finger speed and dexterity
sensation
the information or an impression carried by the afferent nerve to the sensory motor cortex. Without the brain to process the information it is useless on its own
Sensibility
the ability to perceive, recognize and discriminate sensation as well as recognize a change in sensation or the presence of sensory impairment
sensory recovery
what comes back first
1) pain and ability to identify temp
2) vibration at 30 cps
3) moving touch
4) constant touch
5) vibration at 256 cps
6) moving two point discrimination
7) static two point discrimination
sensibility assessment- Moberg Pick Up Test
common objects placed- timed (with and without vision)
being able to identify objects without looking
-looking to see what fingers they use. Do they shift objects to ulnar side of hand? Do they keep items on medial side of hand?
purpose- functional sensibility test. Identification of textures and shapes. tactile gnosis tests.
designed for carpal tunnel identification
Median N damage individuals will shift objects to ulnar side because they still have sensation there
2 point and moving 2 point discrimination
peripheral is distal to proximal- need to find out where nerve is functioning and where it is not. we are looking at the return of function.
-looking at finger tips and up.
if they can identify 7 of 10 objects (can bump down to smaller sized objects if too easy.
2 point moving discrimination
necessary for the ability of the hand to recognize objects
- sweep instrument proximal to distal.
- 7 out of 10 responsed required.
- has to be straight up and down.
2mm- normal score
2 point static discrimination
innervation density test that measures multiple overlapping peripheral receptive fields and the density in the region being tested.
7 out of 10 responsed required to be scored.
norm is 0 to 5 mm
