Posture Monitoring and Correction Exercises for Workers in Hostile Environments Utilizing Non-Invasive Sensors:...

Area of Science:

• Occupational Health and Safety
• Biomedical Engineering
• Ergonomics

Background:

• Workplace safety is crucial, with personal protective equipment (PPE) being a key factor.
• Harsh working conditions and prolonged hours can lead to musculoskeletal disorders (MSDs), often caused by hazardous manual tasks.
• MSDs affect muscles, nerves, and joints, frequently resulting from repetitive motions or sustained force in awkward postures.

Purpose of the Study:

• To develop a framework for posture correction exercises for workers in demanding environments.
• To utilize inertial measurement units (IMUs) for monitoring and analyzing worker posture.
• To identify and mitigate risks associated with work-related musculoskeletal disorders.

Main Methods:

• Collaborative research between Electrical Engineering and Allied Health schools at Curtin University.
• Development of a system using IMUs to record head, back, and pelvis movements.
• Creation of a simulation to analyze posture and assess MSD risk based on established range-of-movement limits.

Main Results:

• The IMU system accurately recorded body movements with 94% accuracy.
• Wrist movement analysis demonstrated a high accuracy of 96%.
• The developed framework effectively determined the range of motion for key body joints.

Conclusions:

• The IMU-based system provides a viable method for assessing posture and MSD risk in occupational settings.
• Accurate measurement of body and wrist movements is achievable with IMU technology.
• This framework supports the development of targeted posture correction exercises for worker well-being.
