PERFORMING GRIP STRENGTH MEASUREMENTS
1. [LB/KG]:
The Jamar Smart Hand Dynamometer is originally set to display in LBs. To change to
KG, open up the battery compartment and move the frequency switch down to KG.
2. Adjust the grip handle to best suit patient comfort and test requirement (See Adjusting Grip Posi-
tion, page 7).
3. Press the
[ON/OFF]
key to start the instrument.
4. Determine which hand will be used. Using the
[SELECT TEST]
key, scroll to the “L” (Left) or “R”
(Right) icon to select the hand to be tested.
5. To select the number of test repetitions (up to 5) to be recorded for that hand, press the
[# OF TRIALS]
key. Each of the five numbers (1 through 5) will be displayed on the upper line of
the display. Stop scrolling on the number which represents the number of tests to be taken.
6. Have the patient grasp the Jamar Smart Hand Dynamometer gently so that the palm fits comfort-
ably to the rear of the instrument and the fingers curl around the adjustable grip at the front of the
instrument.
7. Press the
[TEST]
key to begin the test. Under the present test protocol, start with the first test trial
and the number “1” will appear and flash at the top of the display, indicating that the first test for
the chosen hand is ready. Have the patient squeeze the grip and be ready to enter the second trial
(if test protocol setting has more than 1 trial).
8. When the first test is completed, press the
[TEST]
key one time to scroll to the next test. Repeat
the number of trials to complete the test cycle for the chosen hand.
Example:
The right hand is chosen to perform four tests. Press the
[SELECT TEST]
key and scroll to
the “R” (Right) icon. Press the
[# OF TRIALS]
key until the number “4” is displayed. Press the
[TEST]
key to begin the test. “R” and “1” will be displayed on the upper line. Have the patient perform the
first test. Press the
[TEST]
key to move the display to “R2”. Have the patient perform the second test.
Press the
[TEST]
key after each test until all four tests have been performed.
