Monitoring and Evaluation of Posture in Office Workstations With Artificial Intelligence

Completed · Not applicable

Conditions studied: Musculoskeletal Pain, Musculoskeletal Injury, Musculoskeletal Strain

In brief

Office workers spend 11.6 hours per day in sedentary activities during the day, leading to increased health risks. Although there is literature on prevalence of musculoskeletal disorders and work station modification for office workers, successful implementation and follow-through of evidence-based recommendations in office environments is extremely challenging. This study aims to validate various techniques for evaluating posture, particularly in the neck, shoulder, and trunk, in order to develop evidence-based feedback for the office desk user. This study will include up to 40 volunteers over the age of 18 who regularly work on computer-based tasks at a desk. Participants will be observed working in a provided work station in a variety of different working postures. Data are collected using electromyography sensors, Kinect camera, and at least two video recording cameras to obtain postural information. Measurement of joint positioning and posture will be completed using an ergonomic screening tool from images collected throughout the testing. Participants will provide information on their level of comfort throughout various body regions in response to working in various positions. This will be an iterative study with multiple positions used to test the positioning of sensors, and the development of suitable algorithms to evaluate posture. The collected data will be used to inform sensing methods for office work posture.
