Battery Saver/Sleep Mode
The microFET3’s self activating 'sleep' mode is designed to extend battery life. The microFET3 goes to
sleep when the unit has not received any input for three minutes. The unit can be 'awakened' from sleep
mode by pressing the Reset button.
NOTE: When using microFET3 RF with FET Stick and software: if the microFET3 has not received any input
for 3 minute or crossed the threshold setting, “sleep” mode will activate and signal transmission will stop.
Simply press the reset button and the signal will start transmitting again.
Testing with MICROFET 3
Manual Muscle Testing
Muscle testing was designed to identify and objectively document muscle weakness, or impairment, rather
than muscle strength. The major advantages of muscle testing using handheld dynamometers compared to the
traditional method are the objectivity of the measurements and the consistency of results as measured by both
single testers over multiple tests, and across multiple testers.
During manual muscle testing the clinician normally assigns value to the test result (without the
microFET3), such as 15, or good fair poor, depending on how much force the clinician estimated that the
patient exerted.
Problems arise however, in attempting to assign consistent scores based on feel, especially
when the patient is retested at later date.
The microFET3 was developed to eliminate the subjective nature of testing by giving clear, accurate,
objective, quantified force measurements. The microFET3 increases testing reliability and accuracy. As a
result, the microFET3 makes manual muscle a testing more reliable diagnostic practice.
The microFET3 is designed to be used with either the "make" or the "break" form of manual muscle testing.
"Make" testing is performed by the clinician positioning the patient to isolate and contract the muscle, and by
carefully placing the device in the proper position and angle to conduct the test. With the "Make" test, the
clinician gets into "power position" a stable position that will provide the clinician the maximum ability to resist
the force applied by the patient. The clinician instructs the patient to apply force against the device, while the
clinician resists. The object of the test is for the patient to exert or "make" the maximum force he is capable of,
using only the muscle being tested. "Make" tests typically run for seconds (slow count of 4). Many people find
it helpful to start the test by announcing "go" and end the test by stating "relax".
"Break" testing is also performed by carefully positioning the patient and the device. The clinician stabilizes
the patient in the isolated position, with one hand, while placing the microFET3 unit in position to exert force
against the limb associated with the muscle. The test begins with the clinician gradually applying force and the
patient trying to resist. The object of the test is for the clinician to overcome, or "break" the patient's resistance.
