Wearable biomechanical technology that helps understand ergonomic risks and reduce manual-handling injuries proactively.

MOVA technology

MOVA is an advanced wearable biomechanical technology designed to help organizations understand, assess, and reduce ergonomic risks in the workplace. The system uses nine lightweight sensor devices—one attached to the torso, sensors on the upper and lower arms (left and right), and sensors on the thighs and knees (left and right)—to accurately capture body movements. Working alongside a dedicated mobile app, the sensors transmit data wirelessly via Bluetooth through the torso sensor, enabling real-time analysis of posture and movement. This technology supports manual handling risk assessments, risk mitigation, and practical training to promote safer and more efficient working practices.

Installing the MOVA MMH App

Uninstall the old version: press and hold the MOVA MMH icon, then tap Uninstall.

Open the Play Store.

Search for MOVA MMH.

Tap Install to download the latest version.

Logging in for the First Time

Location access: required for tasks that involve driving. Go to Settings and choose “Allow all the time.

Once all permissions are granted, return to the app’s home page.

Log in using your login credentials.

Email: provided to you via email
Password: use the default password provided to you.

Important: Internet access is required the first time you log in.

Using MOVA to conduct REBA ergonomic Assessment

This section shows how to conduct an REBA manual-handling risk assessment using MOVA technology in simple steps:,

Step 1: Turn ON and attach the sensors

Turn on sensors: Make sure all MOVA sensors are powered on.

Attach correctly: Fit the sensors as shown in the Getting Started section of the app.

Step 2: Open the REBA Assessment

Go to Risk Assessments: From the home screen, select Risk Assessments.

Choose method: Tap Other methods, then select REBA.

Step 3: Connect to the MOVA device

Scan for device: Tap Scan so the app can find your MOVA device.

Select and connect: Choose the device you are wearing and press Connect.

Step 4: Enter assessment details

Load a profile: Tap Load to select an existing profile, or tap Add to create a new one.

Complete fields: Fill in all required information, then tap Proceed.

Step 5: Calibrate the sensors

Start calibration: Press Start to begin calibration.

Follow poses: Follow the on‑screen instructions and adopt the requested poses—accurate calibration is essential for reliable results.

Step 6: Perform the task

Keep phone with you: Lock the phone’s screen and place it in your pocket.

Carry out the work: Perform your normal tasks while the app records movement data and risk factors in real time.

Step 7: Finish the recording

End of shift: At the end of the shift, take out the phone and tap Stop.

Save and review: Wait for the data to save, then tap Proceed. Once the chart is generated, tap Proceed again to move on.

Step 8: Rate additional risk factors

Complete ratings: Follow the prompts to rate other risk factors and body postures.

Finish assessment: Keep pressing Next until you return to the home screen and the assessment is fully completed.

Important points to remember

Keep the phone close: Always keep the phone with the MOVA MMH app running near you (ideally in a pocket) to avoid losing sensor connection.
Always press Stop at the end of the shift: At the end of the shift, press Stop and progress through the Next screens until the assessment is complete.
Sync over Wi‑Fi: If the phone was offline, open the app again when you have Wi‑Fi so the data can upload to the dashboard.

Powering the device On/Off

To turn on the sensor devices, press and hold the power switch for 3 seconds. The green LED will light up, indicating that the device is powered on. To turn off the device, press and hold the power switch again for 3 seconds.

Fitting the sensors correctly

Attach the sensors

The MOVA sensors are supplied with elasticated Velcro straps and a chest harness, allowing them to be securely and comfortably worn over most types of clothing.

Each MOVA system consists of nine dedicated, colour-coded sensors that are uniquely paired to work together as a single set. Sensors from different MOVA systems must not be mixed or interchanged.

Sensor Placement by Number

Each sensor is numbered and corresponds to a specific part of the body:

Sensor 1 – Right upper arm
Sensor 2 – Right lower arm
Sensor 3 – Left upper arm
Sensor 4 – Left lower arm
Sensor 5 – Chest / torso
Sensor 6 – Right upper leg
Sensor 7 – Right lower leg
Sensor 8 – Left upper leg
Sensor 9 – Left lower leg

Best Practice for Placement

Torso sensor (Sensor 5):
Wear this using the chest harness so that the module sits just above the centre of your chest, near the diaphragm area.

Arm and leg sensors:
Attach these using the elasticated Velcro® straps. Position the sensor on:

The biceps for upper arms
The forearm for lower arms
The thigh for upper legs
The lower leg between the knee and ankle

When standing in a natural, upright position, the sensors should face slightly forward or slightly to the side. The ideal position is between front-facing and side-facing.

Avoid positioning the sensors so they point backwards, as this may reduce tracking accuracy and affect data transmission.

Correct placement of the sensors will ensure the best performance and most accurate results from your MOVA system.

Charging the device

To charge the sensors, use the provided charging cable and connect it to the USB-C port. The amber LED will illuminate while the device is charging and will turn off once it is fully charged.

NOTE

When the sensor is turned on by pressing the power button, the LED colour indicates the battery level. It is recommended to recharge the sensor when the LED shows amber or red.

Troubleshooting

1. Logging In Issues

Check internet: Ensure you are connected to the internet.
Restart App: If the error persists, restart the app.
Forgot Password: Reset your password using the "Forgot Password" link.

3. Good Calibration is mandatory

Follow the calibration steps in the app:
Stand upright and still for a few seconds when prompted.
Adapt an A-pose, Turn left or right as instructed and remain still until prompted.
Follow the prompts in the App UI and also the voice prompts during calibration

5. Recalibrating while using the device

The device can move with movements throughout the day. It can become more sensitive or less sensitive as a result. If that happens, please re-calibrate. To recalibrate,
End the current session.
Select "Reset" in Calibration settings and restart the session.
Alternatively, close and restart the app.

2. 'Device not connectable’ error

Wait a few seconds before pressing the "Start" button again.
Re-scan and reconnect to the device on the previous page.
Ensure the device is powered on.
Restart the app if the issue persists.

4. Bluetooth connection issues

Keep the mobile device within range of the MOVA device.
If the connection drops, the app will attempt to reconnect automatically.
For prolonged disconnections, the session will stop with an error message, and you will need to:
Bring the device back into range.
Press "Start" to resume the session.

6. Internet Connectivity

While the app and device can function offline, internet connectivity is recommended for:
Synchronizing and viewing data smoothly.
Logging in and initial authentication (mandatory).
