Actual (reported)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.

Actual (reported)Change in Pain on the Visual Analog Pain Scale from baseline
A Visual Analog Pain Scale is a ten-centimeter long line in which participants are asked to place a mark from a minimum of 0 (no pain) to a maximum of 10 (worst pain imaginable). Participants respond to pain, discomfort, or other sensations (i.e. numbness) in their R/L Hand/Wrist, R/L Forearm/Elbow, R/L Shoulder, Neck, Upper Back, Lower Back, R/L Hip/Leg, R/L Foot.
Baseline, every 10 minutes the first hour, every 15 minutes the second hour
Posture on the Rapid Upper Limb Assessment
Every ten minutes the first hour, average across the second hour
Participants will complete computer work on a provided monitor and keyboard for two hours. During the first hour, the research personnel will alter the workstation every ten minutes to test various different postures of the neck, shoulder, arms, and trunk. The sequence will include 3 seated postures and 3 standing postures. At the end of the first hour, the participant will be instructed to adjust the workstation independently and continue to work for 60 minutes for an observational session.
Participants are asked to work in a sequence of workstation setups for ten minutes each. The sequence include 1. sitting with workstation adjusted by the participant, 2. sitting with workstation adjusted to promote proper posture, 3. sitting with workstation adjusted to promote unnatural posture, 4. standing with workstation adjusted by the participant, 5. standing with workstation adjusted to promote proper posture, and 6. standing with workstation adjusted to promote unnatural posture. After the sequence of setups, the participant allowed to adjust the workstation in either sitting/standing to work in 60 minutes in their own desired position.
