It is then explained to the client that the objective of the test is to manipulate the handles in such a way
as to keep the stylus on the black star pattern. During the test, the Clock/Counter will record one contact
(error) each time the stylus leaves the black star pattern.
To begin the practice session, place the stylus on the top point of the star. The client is given about one
minute of practice time to move the stylus around the star. After you are satisfied that he/she understands
how the apparatus works, return the stylus to the top point of the star.
Reset the Clock/Counter and stopwatch to zero. Tell the client that when you say “START”, he/she should
begin moving the stylus in a clockwise direction (to the right) around the star. Also, tell him or her that
the score is equally weighted for speed as well as accuracy. Therefore, he/she should move the stylus
around the star as quickly as possible, making as few contacts (errors) as possible.
Turn on the Clock/Counter, tell the person to begin, and simultaneously start the stopwatch. When the
client returns to the stylus to the top point of the star, stop the stopwatch. Then, turn off the Clock/Counter.
Do not reset either the stopwatch or the Clock/Counter, since the score is the total for time and the total
for errors for both tasks.
Next, tell the client that when you say “START”, he/she should begin moving the stylus in a counter-clockwise
direction (to the left) while simultaneously starting the stopwatch. When the person returns the stylus to
the top of the star, stop the watch. The turn off the Clock/Counter and record the scores.
Modifications
A person with an arm prosthesis should be encouraged to try the test, if the individual has a usable
prosthesis, the arm of the apparatus can be held above the handle with prosthetic hook. The test is given
in the normal way.
If the client is unable to grasp the handle, use a rubber band or string around the person’s hand, and the
handle, to allow him or her to control the stylus.
A person with CP should be encouraged to try the test, if he/she is unable to control the stylus, move on to
the next test, and record an “X” (for cannot take) in place of the two scores. If the client appears to have
some control, have him or her try the first task (clockwise). If at the end of the task, the time is greater than
230 seconds and the number of errors is greater than 33, there is no reason to do the second operation,
since the person cannot receive a lower rating. Enter the scores received in the first task.
Scoring
The scores are total times for both tasks and total errors for both tasks:
•
Two-Arm Time: HIGH = 70; AVG = 100; LOW = 200
•
Two-Arm Accuracy: HIGH = 1; AVG = 5; LOW = 20
