Expiration Date: XX/XX/XXXX
Name of test: Grip Strength Dynamometry
Estimated time burden: 5 minutes (including set up and instructions)
Materials:
Laptop
Dynamometer 1
Chair
Record Form
Clipboard
Description:
This is a measure of upper extremity strength.
Set-up:
Turn on the dynamometer and press TEST.
For adults and children, set the
nd
dynamometer on the 2 notch. The dynamometer needs to be RESET
between each trial.
Administration Instructions:
Have the participant sit down in the chair so that her/his feet are on the floor or
foot plate of the wheelchair and her/his knees are at a 90-degree angle
and say, “Now we will be using this machine to measure how strong your
hands are. I will have you squeeze the handle 2 times (1practice and 1
test trial) with each hand while your arm is against your side and your
elbow is bent like this (90 degrees). The handle won’t move, but the
machine will show how hard you squeezed. See?” Show the participant
the force measurement. “Do you have any questions?”

Practice:
Say, “Let’s practice; first we’ll use this (point to the dominant, say your right or left
as appropriate for the participant) hand. When I say ‘squeeze,’ I want you
to squeeze the handle hard but not as hard as you can.” Examiner should
support the dynamometer during testing (see picture above).
Continue, “Ready? 3-2-1-squeeze.” After 3-4 seconds, say, “Stop.” Press RESET
and TEST on the dynamometer before the next trial.
Continue, “Now we’ll practice with your other hand. When I say ‘squeeze,’ I want
you to squeeze the handle hard but not as hard as you can.” Examiner
should support the dynamometer during testing (see picture above).
Continue, “Ready? 3-2-1-squeeze.” After 3-4 seconds, say, “Stop.” Press RESET
and TEST on the dynamometer before the next trial.
Test Trial (dominant):
Say, “Now we’re going to test each hand, beginning with this (point to the
dominant, say your right or left, as appropriate for the participant) hand.
When I say ‘squeeze’, this time I want you to squeeze the handle as hard
as you can.” Examiner should support the dynamometer during testing
(see picture above).
Continue, “Ready? 3-2-1-squeeze! Harder, harder, harder.” After 3-4 seconds,
say, “Stop.”
Record the force exerted to the nearest tenth of a pound on the record sheet
for later transfer to the computer. Press RESET and TEST on the
dynamometer before the next trial.
Test Trial (non-dominant):
Say, “OK, now we’re going to test your other hand. When I say ‘squeeze,’ this
time I want you to squeeze the handle as hard as you can.” Examiner
