microFET3 Wireless Overview
microFET3 is an accurate, portable Combination Force Evaluation and Range of Motion testing system. It is a
battery operated, hand held device weighing less than one pound and fits comfortably in the palm of your hand.
microFET3 provides you with objective, quantifiable data from the time-tested art of “hands-on” manual
muscle and range of motion testing. microFET3 aids in the differential diagnosis, prognosis, and treatment
protocols for the neuromuscular and musculoskeletal disorders.
Recessed into the main outer shell is a polycarbonate overlay with clear lenses for the LCD displays (Liquid
Crystal Display), and 3 membrane switches. A red switch is located to one side of the unit in proximity to
where the thumb or the index finger is positioned during use.
As information from the gauges is processed, it is displayed in two LCD windows. During manual muscle
testing, the Peak Force LCD shows the force being applied against the transducer pad during the test, and it
displays the highest force reached when the test is concluded. The Duration/Secs LCD shows the duration of
the test from the time testing threshold was crossed until the test is concluded.
For inclinometer use the unit is placed on the starting point and an angle is set. The patient moves through the
range of motion and the second angle is set. Then by clicking the cycle switch one more time the difference
between both angles will appear in the left hand LCD window.
The newly updated microFET3 Wireless with radio frequency technology provides convenience for both you
and your patients. The wireless microFET3, when used with HOGGAN microFET clinical software, alleviates
the inconvenience of being wired to the computer and provides easier interaction with patients. A wireless
instrument allows greater freedom in the exam room or testing area, and eliminates dictating the location of the
computer and length of instrument cable so you can move freely during testing.
The microFET3 can also be used as a standalone gauge for capturing individual force measurements for any
muscle test and inclinometry test.

Care and Cleaning
Your microFET3 is built to provide long lasting, reliable service. As with any precision instrument, it
should be used with care. It should not be dropped, banged against hard surfaces, or used as a scale.
The microFET3's exterior surface can be cleaned with damp soft cloth. Small amount of household spray
cleaner can be used. Any cleaner residue should be removed with soft cloth dampened with clean water. We
recommend that you periodically inspect your unit for wear, and proper functioning.
Calibration
The microFET3 comes with a calibration certificate, ensuring that the unit was properly calibrated at the
time of shipment. To ensure continued accuracy and reliability your microFET3 unit should be
recalibrated annually, by a properly authorized service technician.
microFET3 Transporting/Storage
Hoggan Scientific strongly recommends that you store and transport the microFET3 in the hard sided
protective carrying case provided.
Operating Features

LCD Windows
Muscle Testing
Peak Force
During muscle testing the Peak Force LCD (right LCD Window) numerically shows the actual force being
applied to the transducer pad. At test completion, the maximum force value (peak force) is displayed. Refer to
Image D below.
Duration/Sec.
The Duration/Sec. LCD window (left LCD Window) shows the elapsed time (in tenths of second) from the
time the force threshold was crossed until pressure was released. Monitoring test duration is an important
element in maintaining consistency between tests. Also displayed in the Duration/Sec. window is the threshold
setting (Low or High). Refer to Image B below.

Page 6

Muscle Testing/Threshold Button
Pressing the MT/ THRESH button will cause the unit to enter “Muscle Testing” mode. Each successive press
of the MT/ THRESH button will alternate the high/low threshold feature
High: display “H” in the time display and fractional units in the “force” display
Low: display “L” in the “time” display and fractional units in the “force” display.
High is the most commonly used threshold setting. In the high setting, three pounds of force must be exerted
before the microFET3 will begin recording test results. High threshold displays in 0.10 lb. increments during
testing. See Image D below to see Threshold setting set to L –Low.
Image D
Threshold
Threshold refers to the amount of force required before the microFET3 begins recording test data. The
threshold level can be set to either High or Low setting, and is displayed in the duration/force window.
High Threshold
The High Threshold is most commonly used. In the High setting, three pounds of force must be exerted
before the microFET3 will begin recording test data. The High threshold allows for easier placement of the unit,
and reduces false starts. High threshold displays force in 0.1 lb increments (.44N) during testing. The unit
begins recording test data at 3.0 lbs force (12.1N), and records data in 0.1 lb increments up to 150 lbs (.44N
increments to 1320N). Pressing Reset does not change the threshold setting
Low Threshold
The Low threshold setting is designed for more sensitive, lower force readings such as when testing finger
and hand muscle weakness. Greater care must be used when positioning the unit while in the Low setting, as the
threshold of 0.8 lbs (3.6 N) is easily crossed. The unit begins recording test data at 0.8 lbs (3.6N) and records
data in 0.1 lb increments up to 150 lbs (0.8 increments to 1320N) Pressing Reset does not change the threshold
setting.

Inclinometer Button
Pressing the INCL button will put the unit in “inclinometer” mode. Refer to Image C below showing unit in
inclinometer mode.
Image C
Using a “two button” approach the right display shows the “live” readings until the Inclinometer cycle switch,
which is a red button located on the side of the microFET3, is pressed. After the inclinometer cycle switch is
pressed the first reading is moved to the left display, and the right display contains the “live” reading. See
Image D below for location of the red inclinometer cycle switch.
Image D
Pressing the inclinometer cycle switch again “freezes” the data in the right display. Then, press the INCL
button. This will subtract the number in the left display from the number in the right display. The final
inclinometer reading result or angle is displayed in the left display.
To begin the cycle of a new inclinometer test, press the INCL button again. The unit will zero out both displays
to begin the cycle again.

Page 11

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.
Page 12

Multiple published studies have proven manual muscle testing to provide consistent, reliable results, both
across multiple tests by single tester, and across multiple testers. The keys to achieving valid results are proper
patient and device positioning, and consistency of the testing methodology used.
Several noted clinicians and researchers have attempted to document muscle testing norms for specific patient
populations. For example, see: Bohannon, Richard W: Reference Values for Extremity Muscle Strength
Obtained by Hand Held Dynamometry from Adults aged 20 to 79 Years. Arch Phys Med Rehabil, Vol.
78, January 1997). The general conclusion from these studies is that norms for healthy adult populations can
be determined, within broad ranges, with gender, age, and weight being the strongest predictors of muscle
strength. It is important to note, however, that norms are provided with fairly wide standard deviations. Only
individuals whose muscle strength falls more than two standard deviations below the norm can conclusively be
considered 'impaired'.
However, these conclusions cannot be extended beyond the youngest or oldest ranges of the adult populations
tested. For example, research conducted on grade school children determined that developmental differences
between individual children were much bigger factor in determining muscle strength than were age or size.
The most relevant norm for Muscle Testing measures is the patient himself; through his/her identification of
change from what has been his personal norm, left/right comparisons, and progress tracking over time.
For best results, when using the microFET3, be sure to install the proper attachment for the area of the body
being tested: flat round pad for flat, larger surfaces, curved pad for rounded surfaces, and digit pad for fingers
and toes. Check to ensure that the unit is properly positioned for maximum surface area contact and direct force
application.
The microFET3 is ambidextrous. It can be held in either the left or right hand, or you may switch hands
from test to test, depending on stabilization requirements.
For information on positions and manual muscle testing for main muscle groups, refer to the Manual
Muscle Testing Positions Wall Chart included with your microFET3. For additional clarification or how to
test for additional muscle test positions, refer to manuals such as Daniels and Worthingham.
Inclinometer Testing
An Inclinometer is a device that measures a static angle in relationship to the horizontal or vertical, or in
relationship to a determined zero starting point. The MIRCOFET3 Inclinometer is a gauge that uses a sensor to
accurately measure to within 1 degrees. When the inclinometer is moved, the sensor will settle to a stable
position in 0.1 seconds which means you can click the button to mark the angle as soon as the patient stops
moving. This feature makes the measurement process more comfortable for the patient because they do not
have to remain in an uncomfortable posture for any significant amount of time. Single inclinometers provide a
simple and accurate method of measuring range of motion. One hand holds the inclinometer and the other hand
is free to either stabilize or assist the patient through the range of motion.
Page 13

To ensure you eliminate any unwanted movement, mark your testing positions w/tape or a marker. To test the
first position, place the unit on the starting position and set your angle, click (photo 1). Then move the unit to
the second position, click (photo 2). Click the side button a third time to get the (PSP) Patient Starting Position
value. Write that number on the appropriate recording tablet. One more click will start the process over. While
leaving the unit in the second position, click (photo 4). Click the side button a third time to get the (PFP)
Patient Finishing Position value. Now subtract the PSP from the PFP and now you have the true ROM.
Photo 1 Photo 2 Photo 3 Photo 4
Stabilization of Inclinometer
Proper gauge placement and stabilization is critical for accurate measurements. One location that is extremely
difficult to locate, especially on obese patients, is the sacral landmark. With a thick adipose layer one may not
be able to feel a bony location and the gauge may “rock” on the adipose layer. When this occurs, the pelvis
must be stabilized with the free hand over the anterior pelvis for counter pressure while the gauge is pressed
firmly into the soft tissue over the sacrum with an attempt to hold the gauge flat as possible against the sacrum.
It is important to assure that the inclinometer remains flat against the patient’s body part at all times. If one foot
of the inclinometer is not in good contact with the bony landmark, the angle marked will be erroneous and all
subsequent calculations will be inaccurate.
Validity Requirements –Inclinometry Testing
Repeat trial consistency is the main validity criteria for spinal inclinometery. Consistency is based on the
cervical, thoracic or lumbar range of motion numbers only. Three consecutive measurements should fall within
5 degrees or 10% (whichever is greater) of the mean (average) of the three measurements in order to meet
validity. If the mean is below 50 degrees, then each measurement must fall within 5 degrees of the mean and if
the mean is over 50 degrees, then all three measurements must fall within 10% of the mean.
TRIAL 1 2 3
Example:
Total ROM at T12………………………………… 110 110 110
Total Hip ROM…………………………………… 50 55 60
Total Lumbar ROM………………………………. 60 55 50
Mean Lumbar……………………………………... 55 degree
10%.......................................................................... 5.5 degree or 6 degrees
Valid……………………………………………… Yes, 50 & 60 are both within 6 degrees of 55.
Page 14

If the patient does not meet validity, then instruct the patient that they are failing the validity criteria, which is
invalidating the measurements and tell them that they must move further in order to achieve valid results. You
may record up to 6 repeat trials and if validity is not met, then invalidate that portion of the evaluation. The test
may be performed at a later date.
Normative Date- the AMA Guidelines
Norms for spinal inclinometry were developed and published in the American Medical Associations Guides
to Evaluation of Permanent Impairment. These norms are very aggressive, i.e., based on a young population
and they are not age or sex adjusted. A copy of the AMA Guides can be purchased from the AMA office.
American Medical Association
515 North State Street
Chicago, IL 60610
1-800-621-8335
Repeat Trial Consistency –Muscle Testing
The values used for repeat trial consistency, which have been determined from six years testing, is a calculation
of the percentage between peak forces of two consecutive exertions. For example:
Consistency
Trial One: 40.0 lbs. 2.5% - Valid
Trial Two: 39.0
The criteria used for interpretation of validity is as follows:
Intrinsic Hand Muscles
VALID 0-15.0 %
EQUIVOCAL 15.1-20.0 %
INVALID >20.0 %
The criteria used for all other muscles is:
VALID 0-10.0 %
EQUIVOCAL 10.1-15.0 %
INVALID > 15.0 %
Page 15

Recording and Retrieving Test Data
The microFET3 is designed to store and retrieve results for the 30 most recent tests for muscle testing, and 30
most recent test angles for inclinometer testing.
In test mode, results are displayed for the most recent test only. Results for each new test, peak force,
and duration, will be displayed as soon as the test is completed, replacing results from the previous test.
The same applies for inclinometer tests.
Six test record tablets are included with your MICROFET3. Sheets in the tablets provide space for writing the
peak force and the test duration and range of motion data. Additional tablets can be ordered through Hoggan
Scientific LLC.
To retrieve and display saved muscle tests, follow these steps:
1. To put the unit in muscle test data retrieval mode hold down the MT/Threshold button and press and
release the Reset button once.
The unit will display the test number and durations in seconds in the Durations/Sec LCD display (left display)
and peak force in the peak force LCD display (right display) for the first test or test 1. Refer to Image L
