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.

Note: 1. When performing repeated tests, inconsistent placement of the MMT will affect scores.

2. Extreme temperature, especially heat, may affect the values obtained.

3. The MMT cannot tolerate the stress of being used as a ﬂoor scale.

4. Care should be taken not to drop the MMT, as it may affect the calibration.

5. Exceeding the force limit (300lbs./136kg) may permanently damage the MMT and/or

invalidate the calibration.

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.

Function Buttons:

The MMT has ﬁve function buttons that control the menus and allow the selection of

options and settings.

Reset Button: The RESET button is located on the top of the MMT. It is placed for easy

access with the thumb regardless of right or left hand operation. The RESET button clears

the display of all data and sets the zero point for the measurements. Care should be taken

not to apply force while pressing the RESET button. This will cause the MMT to sound

two successive audible beeps and display the following message “Diagnostic Alert Please

Press Reset”. The message will continue to be displayed and the user will not be able to

perform another measurement until the RESET button has been pressed.

Range Button: The RANGE button toggles between high

and low measurement range. An “H” or “L” is displayed

on the Main Measurement Screen to indicate the MMT

rangesetting. Changing the range causes the MMT to

automatically reset and clear all time and force

values.

Scroll/LB/KG Button: The LB/KG button has

dual functionality depending on which screen is

accessed. In the Main Measurement Screen, the

LB/KG button toggles the force measurement scale

between pounds and kilograms. An indicator on

the Main Measurement Screen shows which scale

is selected. When a menu or data display screen

is active, this button becomes a SCROLL button.

The SCROLL button is used to select options by

advancing a cursor from one option to the next.

The SCROLL button is also used to step through the

stored data.

Enter/Store Button: The ENTER/STORE button

has dual functionality depending on which screen

is accessed. In the Main Measurement Screen,

the button is used as a STORE button. Pressing

the STORE button stores the current test data in

the MMT memory. Only the peak force and peak time are stored in memory. When the

menu screens are accessed, the button is used as an ENTER button. The ENTER button is

used to activate settings and menu options. It is also used to clear some errors and warning

messages.

Menu Button: The menu button is used to enter the Main Menu. The Main Menu is used

to select the MMT options and access the sub-menus.

Main Measurement Screen:

The Main Measurement Screen shows all of the current measurement information. This screen is

shown whenever a measurement is in progress. This screen is also the default start-up display.

Peak Force: The peak measurement force is displayed in large numbers on the upper left of

the Main Measurement Screen. This value is the peak pounds or kilograms applied during a

test. Force values are displayed to tenths of a pound (or kilogram).

Peak Time: The peak time value is displayed in seconds on the bottom left of the screen

under the peak force. This number is the time during the test when the peak force occurred.

Time values are displayed to hundredths of a second.

Instantaneous Force: The instantaneous force

value is displayed on the upper right on the

Main Measurement Screen. This value is the

force applied to the MMT at any time.

Running Time: The running time value is

displayed on the lower right of the Main

Measurement Screen. This value shows the total

time that force has been applied. After a test has

ended, this value shows the total length of the

test in seconds.

Range Indicator (H or L): The range indicator

shows if the MMT is set in the high or low

measurement setting. If in kg’s, the high range

will be 0kg - 136.1kg and the low range will be

0kg - 22.6kg. If in lbs., the high range will be

0lbs. - 300lbs. And the low range will be 0lbs. - 50lbs. The range indicator is the upper most

indicator in the center of the Main Measurement Screen. The Range is changed by pressing

the RANGE button.

Scale Indicator (LB or KG): The scale indicator shows if the MMT is set to measure in

pounds or kilograms. The scale indicator is the second indicator in the center of the Main

Measurement Screen. The scale is changed by pressing the LB/KG button.

Low Battery Indicator: The low battery indicator is present when a low battery condition

exists. The low battery indicator is the third indicator in the center of the Main Measurement

Screen.

Time Units Label: The time units label is the “S” on the bottom center of the Main

Measurement Screen. This label indicates that the time measurements are in seconds.

This label does not change.

To download:

1. Plug in the USB download device to the host computer

2. Run the download application software.

During download, the MMT will

attempt to establish communication with

the computer. The computer must have

the download software running and the

USB download peripheral connected for

communication to be established.

3. Point the Infrared port in the bottom of the MMT at the USB download device.

Since the connection is infrared, the line of sight between the computer and MMT must

be free from obstructions. The infrared transmitter on the bottom of the MMT must be

pointed directly at the USB download device. The MMT can not be more than 12 feet from

the download device. If the MMT is more than 12 feet away, errors may result in the data

transmission.

4. Enter the Main Menu by pressing the MENU button

5. Press ENTER to begin download.

If a connection can not be established, an error is given along with two audible beeps. An

option menu is then given which allows (1) a reattempt of communication or (2) canceling

the operation. The download device receives the data and transfers it to the computer

software. The software then checks the data for validity and reports the checksum back to the

MMT. Once the MMT receives the correct checksum, the data registers are cleared. If the

correct checksum is not received , the error message is given and the data is not cleared.

Download Function (continued):

Show Data:
