System Description:
The new Lafayette Manual Muscle Test System (MMT) is a hand-held device
for objectively quantifying eccentric muscle strength. Using the Lafayette MMT,
the peak force required to break an isometric contraction is measured as the
examiner applies force against the subject. The Lafayette MMT readily lends
itself to large, pre-participation screenings or field examinations where bulky,
more expensive systems do not. The microprocessor control allows for storage
of calibration values and automatic drift compensation, resulting in reliable,
accurate, and stable muscle strength readings. The MMT also features interactive
menus to allow a wide range of options such as data storage and preset test times
to be implemented. While powerful and versatile, the MMT is still small enough
to fit comfortably in the palm of the hand. Its ergonomic design allows for both
patient and tester comfort while easily conforming to most manual muscle testing
protocols.

(3) LCD Screen
Basics of Operation:
The Lafayette MMT is small enough to be held in
one hand and easily read. The size and weight of the
MMT permit the examiner to use the same
procedures and break test techniques
(described in the literature and taught
by academic institutions) without
any modification of technique or
positioning. The unit is simply placed
between the examiner’s hand and the
limb being tested. The examiner’s
downward force is transmitted to the
limb through the MMT unit. The MMT is
designed for one hand operation.
It can comfortably fit in the right or left hand.
The hand is placed under the strap and around
the body of the MMT. This allows easy access to the
RESET button (1) with the thumb. All of the other buttons are pressed using the opposite
hand.
The MMT is activated by sliding the power switch to the “ON” position (2).
Measurements are taken by pressing the padded stirrup against the muscle being tested on
the subject. The force and time data are displayed on the LCD screen (3) on the face of
the MMT.

Note 1:
Note 2:
For maximum battery life, turn the MMT OFF when not in use. While battery
saver mode greatly reduces the strain on the battery, the battery does still lose a
small amount of power.
Battery saver mode will only activate from the main menu screen. If the MMT is
left in a menu or sub-menu, the battery saver mode will not activate.
Battery Saver Mode:
The MMT has a built-in battery saver mode to power down the circuitry when the device is
not in use. This reduces the wear on the battery and prolongs battery life. The Battery Saver
Mode is initiated after two minutes of inactivity on the MMT. When in battery saver mode, the
LCD and measurement circuitry are powered down. This will result in the screen going blank.
To wake up from Battery Saver Mode:
1. Press one of these four buttons: RESET, MENU, ENTER or SCROLL
2. Pressing the RANGE button does not wake up the MMT
Low Battery Detection:
The MMT is equipped with circuitry
to detect when the battery is low on
power.
Low Battery Detection guidelines:
1. The MMT uses two methods to indicate a low battery condition.
2. The first is a battery icon displayed in the center of the Main Measurement Screen.
(See Main Measurement Screen on page 7.)
3. The second is an audible beep with an error message that requires a button response.
(See errors and warning messages on page 16.)
4. The low battery error message is given every time the MMT is turned on or is reactivated
after being in Battery Saver Mode.
5. The battery will run for about 10 hours after a low battery condition is detected.
6. Stored test data is NOT affected by a low or dead battery. Removing the battery will not
result in any loss of stored data (current test data that is not stored will be lost).
7. Accuracy of the force or time measurements are not affected by a low battery condition.
For directions on changing the battery, see the Battery Change description on page 15.

Caution: You must turn off the MMT when changing stirrups.
Stirrup Change:
The MMT comes with three interchangeable stirrups. Each stirrup is designed for different
test applications depending upon what manual muscle test method is used. The flat stirrup is
used for muscle testing in flat areas such as the forehead and back. The large curved stirrup is
used for large limbs such as the arms and legs. The small flat stirrup is for small digits. Each
stirrup is padded for patient comfort. To change stirrups, simply pull the stirrups off of the
shaft and slide the new stirrup on. The stirrups attach to the shaft via a “press fit.” No tools
are required to change the stirrups. In the event that a stirrup breaks or becomes soiled, new
stirrups may be ordered through Lafayette Instrument Company.
Error and Message Screen Summary:
The MMT has special message screens to indicate when certain operations are
completed or when an error has occurred. Selected error messages must be
acknowledged with a user response before normal MMT operation can resume.
Warning messages that require a user response are accompanied by two successive
beeps. The user must press ENTER or RESET to acknowledge the message and
continue operations.
The message screens are as follows:
Low Battery Warning:
This warning is given when a low battery condition has been detected. The warning
is accompanied by two audible beeps. The warning is only given when the device is
turned on or is waking up from Battery Saver Mode. During normal operation, a low
battery condition is also indicated by a battery icon on the Main Measurement Screen.
The low battery warning is
acknowledged and cleared by
pressing the ENTER button.

Memory Full Warning:
This warning is given when the memory capacity has been reached. The MMT is
capable of storing up to 52 tests. Once this number of stored tests is reached, the
MEMORY FULL error message is given each time a new storage command is given.
This includes both Auto-Storing and manually storing the data. The MEMORY FULL
error is accompanied by two audible beeps. The user must press the ENTER button
to acknowledge and clear the warning. They must then either discontinue storage
by disabling the AUTO STORE feature or erase the stored data in memory. Failing
to do one of these steps will
result in continued warning
messages. Data that triggers a
MEMORY FULL warning is
NOT stored in memory.
Diagnostic Alert Please Press Reset Message:
This message is displayed whenever force is applied to the MMT at the same time that
the RESET button is pressed. This message is accompanied by two audible beeps.
The user must press RESET to clear this error message. The MMT will not register
any new force measurements until the RESET button is pressed.

Appendix A - Torque Measurements with the MMT
In some research and rehabilitation applications, it is necessary to obtain torque measurements
for the limb being tested. Torque is often a more accurate indicator of total strength because
it takes into account the length of the muscle being tested. The Lafayette Manual Muscle Test
System (MMT) can be used to obtain torque values through a series of basic calculations.
Torque is measured in units of Newton meters (Nwm) in the Metric system and in foot pounds
(ftwlbs.) in the English system. Torque is the product of the force applied times the distance
between the force and the pivot point (usually a joint).
Equations for obtaining torque readings with the MMT using metric values:
Torque = Force x distance
Where force equals the MMT reading converted to Newtons and distance is the length between
where the force is applied and the joint being tested in meters.
Newtons conversions:
1 pound = 4.45 Newtons
1 kilogram = 9.81 Newtons
Normative Strength can also be quantified as torque per kilogram bodyweight (Nwm/kg). This
value is obtained by dividing the torque by the person’s bodyweight in kg.
Strength = ((MMT reading in Newtons) x (distance))
bodyweight in kilograms
