Signing In

If you already have an ActivForce account, enter your email address and password to sign in. If you don’t remember your password, click on the “Forgot Password?” link.

Home Screen

Upon signing in, you will see the ActivForce home screen. Choose the type of measurement you want to perform: Range of Motion or Strength.

Range of Motion Measurements

The ActivForce app can obtain angle measurements in 3D space from a starting position that is established during the calibration phase. Two types of Range of Motion (ROM) measurements can be conducted: Active Range of Motion (AROM) and Passive Range of Motion (PROM).

1/8

After selecting Range of Motion from the Home Screen, you can choose to perform an “Active Range of Motion” test, “Passive Range of Motion” test or “Both”. Selecting “Both” will perform an AROM test, followed by a PROM test.

The app allows you to customize your test by selecting which side(s) to test - Right, Left, Both or N/A (if no side is applicable).

If “Both” is selected, you will be asked to select which side to test first. This selection will be applied to all test types previously selected.

Before the test is started, the test can be named either manually or by selecting suggested joints, movements and positions. The test naming can also be skipped by tapping the “Skip” button at the top right corner.

Upon reaching the test screen, you can start the ROM measurement by tapping the “Start Test” button. After pressing the “Start Test” button, a short calibration phase will commence. Do not press or move the device during the calibration phase.

The ActivForce 2 device is capable of measuring angles in any of the three axes, but only one angle, in a single plane of motion, should be measured for each test.

If more types of measurements or sides are selected, the app will display instructions to prepare for the next test in the sequence (Switch the side or Continue with the position). After the measurement is concluded, tap the “End Test” button.

Once the “End Test” button is pressed, you have two options: to either see the test results by tapping on the “View Summary” button or to perform the last measurement again by tapping “Redo Test”, which will discard the previous result and restart the measurement process.

Tapping the “Save and Exit” button will save the report to the signed-in account to be accessed from the ActivForce Dashboard.

Tapping the “X” close button will not save the report and it will not be accessible from this account’s ActivForce Dashboard.

Strength Measurements

To perform a strength test, select the “Strength” button on the home screen.

1/8

On the first screen, select which side to test first - Right, Left or N/A (if no side is applicable).

Before the test is started, the test can be named either manually or by selecting suggested joints, movements and positions. The test naming can also be skipped by tapping the “Skip” button at the top right corner.

Once you reach the test screen, you can start the Strength measurement by tapping the “Start” button. A three-second calibration phase will commence. Do not press or move the device during calibration.

After calibration, a “Go!” label will be shown, indicating that the test can be started by applying force to the device.

Once the test is started, force applied to the device will be displayed in the app.

The duration of the test depends on the predefined settings set in the “Settings” screen (defaulted to six seconds). After the test is completed, the app will present a choice: continue with the test and switch to the next side by tapping “Next Side” or perform the measurement again by tapping “Redo Test” which will discard the previous result and restart the measurement process.

When the “Next Side” button is pressed, the app will display instructions to prepare for the next test and side in the sequence (Switch the side).

After the strength test has been completed, a Summary screen with graphs and data showing Force over time, Peak Force and Force to Weight Ratio will be displayed. From the Summary screen, the strength test data can be saved to the Activforce dashboard, or another measurement can be added.

A test report in the dashboard will contain the information recorded during the administration of the test.

The dashboard will also contain all test summaries for a client in a Client Report, accessible by clicking on the “Client Report” link from the dashboard home page.

Attaching a Pad to the Device

The locking mechanism is a circle with four wide gaps that securely hold attachments in
place through a twist lock mechanism. To secure an attachment to the ActivForce 2 device:

1. Align the attachment teeth with the locking mechanism gaps.
2. Push the attachment teeth down into the gaps.
3. Twist the attachment clockwise (towards the locked symbol) a full quarter turn.
4. When locked, the attachment will remain in place.

Measuring Force

The ActivForce 2 device measures accurately when force is applied in a perpendicular direction to the large surface areas of the device or an attached pad. Application of the force should be in the center of the surface as much as possible. Direct all force into the device directly perpendicular through the device’s center point.

• Do not apply force in a non-perpendicular direction to the device.
• Do not apply force at an angle or in a direction going across (parallel to) the device.
• Do not apply force on or near to the blue band of the device.
• Do not apply a force during the three-second calibration period before the application starts the force measurement.
• Do not move or shake the device during the force measurement.

Measuring Range of Motion

The ActivForce 2 device can also measure angular displacement for range of motion testing. While the device is calibrating, make sure that the device is being held still in the starting position.

• Do not rotate the ActivForce 2 device in multiple axes during a measurement.
• Do not move the ActivForce 2 device in multiple planes of motion during a measurement.
• Do not rotate the device during the brief calibration period before the application starts the range of motion measurement.

1/2

Place the device and/or subject into the starting position for test measurement and press the "Start Test" button.

After calibration, move the device from the starting position (Position 1) to the ending position (Position 2) through one plane of movement only (frontal, horizontal, or sagittal).

App Security

Sign in and out of the app or use the security features on your mobile device to ensure data privacy. Your data within the app is encrypted and accessible only with your username and password. Do NOT share your username or password with others. Always comply with local regulations on data privacy.

The Hand & Leg Straps

The Hand Strap

When using the Hand Strap attachment, ensure the strap is securely fixed in position. The Hand Strap may be used to secure the device to the user for strength and range of motion tests.

The Leg Strap

When using the Leg Strap attachment, ensure the strap is securely fixed in position. Use the Leg Strap to attach the device to the subject’s larger body parts for range of motion tests.

Threading the Hand and Leg Strap

Thread the strap through both loops with the logo face up and the plate face down. Place the device so that the locking mechanism fits into the hole in the plate. Slide your hand between the device and the strap. Pull the non-logo side across your hand. Pull the logo side over and secure the velcro. Use with desired attachment.

The Different Pads

1/3

Arched Pad

When using the Arched Pad attachment, ensure the attachment is securely attached in the locking mechanism. Use on hard or bony body parts for strength tests. The curve of the Arched Pad surface can be used to place the device against curved body parts.

Foam Insert, Silicone Cover and Arched Pad

Use of the Foam Insert and Silicone Cover is optional. For additional subject comfort, the Foam Insert can be attached to the Arched Pad by removing the adhesive backing and adhering it to the surface of the Arched Pad. The Silicone Cover can be secured in place using the grooves in the silicone to fit around the Arched Pad, providing a non-porous surface which can be easily cleaned and disinfected between uses.

To ensure accurate measurement and prevent the slippage of the device or Silicon Cover during measurement, force should only be applied in a direction perpendicular to the Pad surface.

Rounded Pad

When using the Rounded Pad attachment, ensure it is securely attached in the locking mechanism. Use this pad for all grip strength measurements and when bracing a test position against an immovable object.

The Immobilization Belt & Belt Loop Plate

When using the Belt Loop Plate immobilization belt attachments, keep the belt positioned perpendicular through the loops to reduce strain on the belt loops. The plate is designed to hold the belt in position during a test and it is not designed to withstand force from a test. No force should be applied on the loops for a more accurate measurement. Keep the straps parallel to the direction of applied force so the force is transmitted to the device. Ensure the belt is wrapped over the smooth side of the device and not over the attachment side of the device.

The Round Pad with the Belt Loop Plate is recommended when the device is being pressed into the inanimate object. The Belt Loop Plate may be used to guide the belt when the device is strapped to a fixed or immobile object.

The Belt Loop Plate

Incorrect Strap Positioning and Correct Strap Positioning (parallel to direction of applied force).

Cleaning and Disinfecting the Device

To prevent the spread of infection and diseases, the ActivForce 2 device and pads should be disinfected between each use. The ActivForce 2 device’s external surfaces, including the rounded pad and the soft, arched pad silicon sleeve, can be hand wiped at room temperature with a soft cloth and a cleaning solution consisting of 70% isopropyl alcohol and water. After application, the cleaning solution should be allowed to evaporate completely.

Alternatively, a cleaning solution of 1% hypochlorite and water (10,000 ppm) can also be used to wipe the device, pads and silicon sleeves. Antibacterial hand sanitizing agents such as non-alcohol wipes or alcohol-based hand gels may also be used. Any residue from these agents should be wiped away using a soft, dry clean tissue or towel.

Replacing the Battery

The ActivForce 2 device comes with a standard AAA battery, which lasts between six to twelve months, depending on usage and environmental conditions. To replace the battery, follow these steps:

1/6

Obtain a new AAA battery and a medium size flat-head screwdriver.

Hold the ActivForce 2 device and the screwdriver with the pad attachment mechanism facing upwards. The Activforce logo should NOT be visible.

Insert the tip of the screwdriver in the small opening near the power button and gently turn the screwdriver until a click sound is heard and the bottom shell lid pops slightly open. This opens the first of five latches on the bottom lid.

Gently slide the screwdriver clockwise along the edge of the ActivForce 2 device, keeping the tip inside the gap between the lid and the device until it is about an inch and a half away from the original opening near the power button.

Stop sliding and gently turn the screwdriver until a CLICK sound is heard. Continue sliding the screwdriver around the edge with the tip inside the crevice, stopping every inch and a half to turn the screwdriver to pop open the latches of the bottom lid. The bottom lid can be removed when four to five of the latches are opened.

Once the lid is removed, you can replace the present AAA battery with a new one.

Once done replacing the battery, you can put the bottom lid back in place.
