Area of Science:

  • Occupational health
  • Biomechanics
  • Ergonomics

Background:

  • Occupational low back pain is a significant issue, often linked to lifting tasks.
  • Current screening tools for lifting-related risks may lack precision.
  • Trunk flexion angle and velocity are key biomechanical factors in low back pain development.

Purpose of the Study:

  • To develop and validate a mobile application for measuring trunk flexion angles.
  • To provide ergonomists with a tool for refined assessment of lifting tasks.
  • To improve the screening of occupational risk factors for low back pain.

Main Methods:

  • Utilized mobile device accelerometers to approximate trunk flexion.
  • Developed a visual aid (superimposed black line) for angle estimation.
  • Tested the application during sagittal plane lifting tasks.

Main Results:

  • The application provides quick and repeatable measurements of trunk flexion angles.
  • The tool allows for estimation of trunk inclination between specific vertebrae.
  • Offers a more refined measurement compared to existing survey methods.

Conclusions:

  • The developed mobile application is a viable tool for assessing trunk flexion during lifting.
  • This technology can enhance the ergonomic assessment of occupational low back pain risk.
  • Provides a more objective and accessible method for ergonomists.
