9. When testing is completed for the chosen hand and the required data is recorded, press the
[RESET]
key to clear the previous test data. Repeat steps 4 through 9 for the remaining hand if de-
sired.
10. To alternate left and right hand tests (i.e., L1 - R1, L2 - R2, L3 - R3, etc) press
[SELECT TEST]
until both the “L” and “R” are displayed. The instrument will automatically alternate “L” and “R” hand
test cycles.
11. Press the
[ON/OFF]
key to turn the instrument OFF when testing is complete and return it to a
safe storage location.
RECORDING GRIP STRENGTH MEASUREMENTS
Upon completion of the desired tests for a patient’s left and/or right hand, the therapist can select one
of two methods for recording the data obtained by those tests.
1. After each individual test, the therapist may choose to record the data displayed on the instrument
and perform subsequent calculations at a later date.
2. After all the test trials are completed, the therapist may choose to review the test results stored
in the Jamar Smart Hand Dynamometer. All the test and calculation results can be viewed on the
display by repeatedly pressing the
[TEST]
key. All results will be displayed in the sequence of:
Test Trial 1, Test Trial 2...Test Trial N, AVG, STDEV, CV. There will be an indicator icon shown in
the display for each respective result.
CALCULATIONS
Three important calculations are performed automatically by the Jamar Smart Hand Dynamometer:
Test Average, Standard Deviation, and Coefficient of Variation.
Test Average:
Each reading taken for the left hand or right hand is recorded in memory for that
hand. When the test is completed, the Therapist uses the
[TEST]
key, located in the lower left of the
keypad, to review the average measure of the multiple test trials.
Standard Deviation:
The Jamar Smart Hand Dynamometer calculates the standard deviation of
reading taken. Use the
[TEST]
key to review the standard deviation of the multiple test trials.
Coefficient of Variation:
To obtain disbursement data, the instrument divides the standard deviation
by the average as shown below. Use the
[TEST]
key to scroll to the “CV” icon to display the result.
