Process Flow Create the Survey • Researched pain scales and similar surveys • Created multiple drafts of the survey, got feedback • Submitted project proposal and survey draft to IRB Send Out the Survey • For ease of completion and collection, we did not use hard copies • Sent out using the online survey platform Qualtrics Collect Data from the Survey • Data was recorded and viewed through the Qualtrics website Analyze the Data • Determined actual KPIVs, time spent for pain related breaks Complete a Cost. Benefit Analysis • Determine if the cost of each workstation is justified by the potential benefits Make Final Recommendation • Determine if adjustable workstations are a worthy investment for Ohio University 6 Height Adjustable Workstation Assessment

Process Analysis • After the survey was completed, we analyzed the data and made inferences – Looked for correlations between how they use the workstation, their daily habits, etc. , and their reported pains • Cost-Benefit analysis was performed comparing… – Cost of adjustable workstation – Savings associated with change in productivity 11 Height Adjustable Workstation Assessment

KPIVs • Correlation values were calculated for different factors that could contribute to a worker’s pain • KPIVs were determined to be: – – BMI: r=0. 488 Hours standing outside of work: r=0. 500 Age: r=0. 687 Number of position changes: r=0. 588 • (N=15, α = 0. 1) • Correlation does not always mean causation 12 Height Adjustable Workstation Assessment

Summary of Results • Frequency of pain – Decreased in 6 of 8 areas, but increased in the feet • Severity of Pain – Decreased in all areas except feet and legs where it increased • Length of breaks due to pain or discomfort – Fewer and shorter breaks required to relieve pain • Overall Opinion – More productive, increased comfort, improved mood, would recommend HAWs to everyone 17 Height Adjustable Workstation Assessment

Findings from Other Studies • Effects of An Electric Height-Adjustable Worksurface on Self-assessed Musculoskeletal

Findings from Other Studies • Effects of An Electric Height-Adjustable Worksurface on Self-assessed Musculoskeletal Discomfort and Productivity in Computer Workers – Alan Hedge of Cornell University, 2004 – Found significant decrease in severity of pain in shoulders, neck, upper back, lower back, forearms, wrists, and hands – Found slight significant increase in frequency of pain in the same areas – Lower increase in discomfort ratings throughout the day – 57. 2% said it “somewhat/definitely helped” with productivity – 82. 4% of participants preferred the EHAW 18 Height Adjustable Workstation Assessment
