ErgoArmMeter is a professional inclinometer for measuring and recording arm elevation during work. It is shown by research that work with elevated arm may lead to shoulder/neck disorders. Ergonomists have been using inclinometers to measure arm elevation, which have a better precision compared to self-reports and observations of arm elevation. With ErgoArmMeter, arm elevation during work time can be measured easily and with low cost. ErgoArmMeter is validated that it has similar accuracy compared to other former validated inclinometers.

How to use (also accessible in the app):

Attach the phone using a sport armband on the upper arm, with the upper edge just below the deltoid muscle, then:

1. Start a measurement by clicking “+”, fill in a project name and a recording number and “Create” the trial.

2. Conduct calibration by leaning to the side, holding some weight (e.g. a 2 kg dumbbell) with a straight-arm, and click “Calibrate”, keep the posture for 2 seconds.

3. Click “Start” to start the measurement, time is shown, and the arm elevation angle is recorded.

4. Press “Stop” to end the measurement and view the results.

5. Click “Share” to save the results in the phone's local storage.

ErgoArmMeter is designed be used in evaluating workplace before and after interventions. It can also be used for educational purpose. Together with other information about the work task, it can add valuable information for risk assessments of a certain work task.
