  2. Finger and Hand Dexterity • Three Functional Capacity Tests to be discussed are: • 1) Perdue Pegboard Test • 2) Complete Minnesota Dexterity Test • 3) Epic Hand Function

  3. #1 Perdue Pegboard Test • What is the Perdue Peg Board Test? • Since its development in 1948 by Dr. Joseph Tiffin, this test has been used extensively to aid in the selection of employees for various types of manual labor. It measures dexterity for 2 types of activities: gross movements of hands, fingers, and arms; and fingertip dexterity necessary in assembly tasks.

  4. Perdue Pegboard Test • This image demonstrates an individual placing pegs into the right column of the pegboard.

  5. Purdue Continued • The Purdue Pegboard was standardized after extensive experimentation in numerous plants involving the testing of several thousand employees in a wide variety of industrial jobs. • The pegboard is equipped with pins, collars, and washers which are located in four cups at the top of the board.

  6. Purdue • It can be administered to individuals or groups. It is timed as follows: Right hand: 30 seconds, Left hand: 30 seconds, Both hands: 30 seconds, and assembly: 1 minute. • Right hand: place as many pegs into holes • Left Hand: place as many pegs into holes • Both Hands: place as many pegs into holes • Assembly: Using both hands, place a peg, a washer, a collar, and another washer into as many pegs • Entire testing period is about 10 minutes and it is hand scored.

  7. Purdue Scoring • Scoring is done by counting the number of pieces placed into the holes in the given time restraints.

  8. Purdue Validity • The results show that the test-retest reliability is good (intra-class correlation coefficients from 0.66 to 0.90, depending on the subtest). • Norms are presented to help clinicians involved in rehabilitation services to better differentiate real dexterity deficits from those that may be attributed to normal ageing.

  9. #2 Complete Minnesota Dexterity Test • The CMDT is designed to provide employers with an instrument that will improve the efficiency of personnel selection for jobs requiring arm and hand dexterity. Five tests can be performed. These are: turning, placing, displacing, the one hand turning and placing test and the two hand turning and placing test.

  10. CMDT • Used to measure a subject’s simple but rapid eye-hand coordination as well as arm-hand dexterity. In General, the CMDT measures gross motor skills. • It can be used for many testing applications. Physical therapy, Occupational therapy, vocational evaluation, and pre-employment screening are four uses for this test.

  11. CMDT • Placing Test: • The object of this test is to see how fast you can put the disks from the top board into the holes of the bottom board using only one hand. • You will want to use your dominant hand.

  12. CMDT • Turning Test • The object of this test is to see how fast you can pick up the disks with one hand, turn them with the other hand, and replace the disks back into the holes on the board.

  13. CMDT • Displacing Test • Remove the disk from the upper left-hand corner (top hole in the first column_ and put it to the side. This is the starting position for the displacing test. The object of this test is to see how fast you can move the blocks from one hole to another. You can use either hand for this test.

  14. CMDT • One-Hand Turning and Placing Test • The object of this test is to see how fast you can pick up the disks from the top board, turn the disks over, thus showing the other color of the disk, and place them into the holes of the bottom board. This is to be done using only one hand. You will want to use you dominant hand.

  15. CMDT • Two-Hand Turning and Placing Test • The object of this test is to see how fast you can pick up the disks from the top board, two at a time (one in each hand), turn the disks over, thus showing the other color of the disk, and place them into the holes of the bottom board. This is to be done using BOTH hands.

  16. CMDT Scoring • The score on any test of the CMDT is the total seconds required to complete the chosen number of test trials. Two, three, or four test trials may have been administered. Practice time is not included in the total score.

  17. CMDT Validity • In a report concerning the use of the CMDT, a group of men hired as converting machine operators in a paper mill were tested and scored, and then ranked on a scale of 5. ratings were converted to T-scores. Reliability of this testing was estimated to be 0.75.

  18. #3 Epic Hand Function Sort • The 62-item Hand Function Sort (HFS) helps quantify a disabled person's perception of ability to perform work tasks that involve hands and upper extremities. By comparing this report with functional test results, magnification or minimization of dysfunction can be identified.

  19. Epic Hand Function • Where is it used?In treatment programs, the patient’s progress can be documented easily. The HFS provides a baseline measure of function in everyday tasks, to compare to progress in subsequent treatment, extending the benefits beyond the clinic’s walls, into the patient’s life at home, at work, and in the community. In comparison with functional tests, magnification of dysfunction can be identified.

  20. Epic HFS • Where is it used? Cont… • In employment screening programs in industrial settings, the HFS compares the job applicant’s current abilities to job demands and sets a baseline of abilities.

  21. Epic HFS • How is the test done? • The HFS is an untimed paper and pencil test. The evaluee is instructed to “Look at each drawing and read the description. On a separate answer sheet, indicate your current level of ability to perform the task.” • The answer sheet provides a 5-point rating from “Able” to “Restricted” to “Unable.” Operational definitions of these adjectives are provided in the standardized instructions. There is also a sixth rating which is depicted as “?” and indicates, “I don’t know.”

  22. Epic HFS • The picture shown is an example of a task that is illustrated in the test.

  23. Epic HFS Scoring • The HFS is easily scored by hand and yields a single "Rating of Perceived Capacity" which ranges from zero to 248. Three "internal validity check" drawings are included that are similar to drawings presented earlier. These are used to screen for inconsistent responding, along with a graded scoring strategy that evaluates intra-test consistency.
