Wireless Grip
(9RF306)
Used to convey functional abilities concerning grip strength.
Features and Benefits
Grip Dynamometer:
•
Uses standard gauge for comparison to published norms.
•
Up to eight repetitions per side.
•
Helps determine consistency of effort in workers compensation and FCE exams.
•
Measures up to 200 pounds for very strong performers.
•
Test protocols can be customized according to number of tests, starting force, newtons/kilograms/pounds,
test time and number of repetitions.
•
Axis Compensation
TM
“smart” load cell technology. Maintains accuracy even when force is applied off-
center.
General Grip Testing
In order for a grip test to be used as a validity check, a minimum of two repetitions must be performed
bilaterally. Additionally, to obtain fatigue data the test must be timed (see Setup Mode on page 7). Validity is
based on the coefficient of variation (CV) of the completed repetitions for the hand and grip position. Generally,
CVs greater than 15% denote inconsistency of effort. If a strength deficit greater than 15% exists bilaterally,
weakness is indicated. For proper documentation purposes, make sure that the grip position corresponds with
the test number selected on the Commander Echo Console.
Prior to beginning a test, ensure that the test defaults are set as desired (i.e. unit of measurement, number of
tests, number of repetitions, etc.). Once test defaults are set, choose the “Test” option from the main menu,
and follow these steps:
1 .
Select “Grip” from the Test Menu (Note: if you have purchased a new instrument and it is not on the list,
see page 18 for instructions or contact customer service to register your new instrument).
2 .
Upon selection, the Commander Echo Console will attempt to connect with the chosen instrument.
3 .
Press the “On” button for the corresponding instrument to establish a connection with the Commander
Echo Console.
4 .
The Commander Echo Console will require a instrument zeroing prior to starting each exam. With the
instrument in a neutral position (no pressure applied), press the Control Stick to set the instrument zero.
5 .
The Commander Echo will automatically advance to the next available test in the series. If no test data is
currently being stored for the instrument, it will begin with Test 1. If all of the selected tests already have
data stored, then the Commander Echo Console will display Message 2 on the LCD and not allow further
testing until the data has been erased, or the test settings have been altered to allow for more tests.
6 .
Ready the patient and begin the test (Note: see the optional Multimedia Help System CD for further
information on specific testing procedures).
7 .
Once you have completed the pre-set number of repetitions for each side/test, the Commander Echo will
automatically advance to the next test in the exam.
8 .
Once all tests have been completed, the Commander Echo Console will display Message 2 on the LCD to
notify you that there are no more empty tests available. Pressing the Control Stick will bring you back to the
main menu.
