ErgoArmMeter

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.

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.
To view the results, click on the trial name in the trial list.

5.
- Click Share to send the results and the whole data set via email.

Notice:

Since ErgoArmMeter uses accelerometer and gyroscope in the phone, it requires the phone remain unlocked to stay functioning.
