The Lafayette Hand-held Dynamometer (HHD) is an ergonomic hand-held device used for objectively
quantifying muscle strength. The test is performed with the clinician stabilizing the dynamometer
to the limb of a patient. The objective of the test is for the clinician to resist the patient’s applied
force. The HHD records the peak force and the time required to achieve the force providing reliable,
accurate, and stable muscle strength readings.
The HHD also features interactive menus to allow a wide range of options such as data storage, preset
test times, and force thresholds to be implemented. While powerful and versatile, the HHD is still

• Exceeding the force limit (300lbs/136kg/9999kPa/1335N) may permanently damage and/or
invalidate the calibration of the HHD.
• Upon initial receipt of HHD, charge for 2 hours.
• This device uses a Lithium-Ion battery as a power source. It is recommended that the battery be
charged at least once every six months. Failure to periodically charge the battery may result in
battery damage or device malfunction.

Basic Operations
The Lafayette HHD is small enough to be held in one hand and easily read. The size and weight of
the HHD permit the examiner to use the same procedures and break test techniques described in the

left hand, with settings for both dexterities. The hand is placed under the strap and around the body
of the HHD. This allows easy access to the TOP buttons with the thumb. All of the other buttons are
pressed using the opposite hand.
The HHD is activated by pressing and holding the Menu/Select button. Measurements are taken by
positioning the padded stirrup against the muscle being tested on the subject. The force and time
data are displayed on the LCD screen. To conserve battery life, the HHD will deactivate itself when not

Screens
Test Screen
The Main Measurement Screen shows all measurement information that is being captured. This screen
is shown whenever a measurement is in progress.
1. Battery Indicator: Indicates the remaining capacity in the charge of the battery.
2. Force over Time Graph Area: The graph displays the data for the previously conducted test, and
automatically populates the chart to maximize the viewing area. The Y-axis label shows the
amount of force (in lbs, kg, kPA, or N), and the X-axis shows the time in seconds.
3. Avg Force: Average force exerted over the range.
4. Total Time: The total time is the total duration of the test in seconds.
5. Time-Peak: Time to peak is the elapsed time in seconds from the start of the test until the
maximum force has been reached.
• Each of these three windows can have any of the following measurements displayed during or
after a test is taken:
• Real-Time Force: This displays the real time force that is measured during the test.
• End Force: The force measured at the end of the test.
• Avg Pk-End: Average force exerted from the peak to the end.
• % Pk-End: Percentage decrease of force from peak force to end force.
6. Top Button Function: This area shows the current function for the top button. In the Test screen
window, the clear function clears the current test, and allows the user to take another test. These
elements can move depending on chosen button orientation in Options menu.
7. Wireless Communication Indicator: This character indicates when the wireless is enabled.
8. Time Display: Time is displayed and can be set manually or synced with a PC in the Options
Menu.

START
Starting a test can either be done by passing a
FORCE THRESHOLD, after a certain amount of TIME
DELAY, or by triggered by the top button.
START FORCE/TIME DELAY
These options allow you to select customized force
thresholds and time delays.
STOP THRESHOLD
If enabled, the test will end when the force applied drops below the value set in STOP FORCE. If
disabled, the test will resume for the amount of time set by the TEST TIME.
STOP FORCE
If STOP THRESHOLD is enabled, each test will be stopped when the force is less than or equal to this
force. Stop force cannot exceed start force.

If enabled, manually clearing the data is not required prior to starting new tests.
Test Setup Menu Screen
The Test Setup menu screen allows the user to select
default or custom settings while also setup various
test options for each custom setting.

Dynamometer Cleaning
Hard surfaces can be cleaned with a bleach-free sanitizing wipe. Alcohol wipes may also be used.
Cloth or foam surfaces can be cleaned with anti-bacterial soap and water and allowed to air dry. Care
must be taken to not allow water to penetrate the enclosure as damage to the circuit may occur.
Disposable sanitary covers are available on the stirrup pad that comes into direct contact with the
patient’s skin. Do not reuse disposable covers.
