standard assessments for hand impairments

Question 1

Standardized vs non-standardized

Answer 1

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)

Question 2

reliability

Answer 2

measure of consistency

Question 3

Inter-rater reliabilty

Answer 3

assesses the degree of agreement between two or more raters in their appraisals

Question 4

Test-retest reliability

Answer 4

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.

Question 5

Validity

Answer 5

A test can be reliable without being valid.

How accurately a test measures what it claims to measure

Question 6

sensitivity

Answer 6

ability of the test to accurately measure the presence of a condition

Question 7

Specificity

Answer 7

ability of a test to accurately identify the absence of a condition

Question 8

standardized tests

Answer 8

procedures are the same very time it is given

Question 9

Purdue peg board

Answer 9

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

Question 10

Minnesota Rate of Manipulation Test (MRMT)

Answer 10

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

Question 11

Jebsen Test of hand function

Answer 11

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.

Question 12

Nine hole peg test

Answer 12

place 9 pegs into 9 holes
-test is timed and patient performance is compared with normative data.

purpose- grasp and release, manipulation.

Question 13

Box and blocks

Answer 13

functional test to measure the patients performance in grasping medium sized blocks

purpose- grasp and release, manipulation.

Question 14

O’Connor tweezer dexterity test

Answer 14

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

Question 15

sensation

Answer 15

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

Question 16

Sensibility

Answer 16

the ability to perceive, recognize and discriminate sensation as well as recognize a change in sensation or the presence of sensory impairment

Question 17

sensory recovery

Answer 17

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

Question 18

sensibility assessment- Moberg Pick Up Test

Answer 18

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

Question 19

2 point and moving 2 point discrimination

Answer 19

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.

Question 20

2 point moving discrimination

Answer 20

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

Question 21

2 point static discrimination

Answer 21

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
