The working environment of the individuals participating in the study will be evaluated with The Rapid Office Strain Assessment (ROSA). ROSA is a picture-based posture checklist designed to quantify exposure to risk factors in an office work environment. In ROSA, three subsections (A-chair height, depth, armrest, and backrest; B-monitor and telephone; C-mouse and keyboard) of the office work environment are assessed. After completing the ROSA checklist, the related tables are used to calculate the score from each part, and eventually, the final ROSA score is derived. If the final score is ≤4; the risk of musculoskeletal disorders is low (low risky). If the final score is ≥5 the risk of musculoskeletal disorders risk is high (high risky).

The NMQ includes 27 items exploring the presence of musculoskeletal symptoms for the last 12 months covering nine different parts of the body. It also has items about severity grades, determined according to functional status and the presence of musculoskeletal symptoms during the 7 days. Symptoms indicate musculoskeletal disorders in different body regions among the working population. The NMQ section that questions the last 7 days will be used in the study. In that section consists additional questions relating to the neck, the shoulders, and the lower back further detail relevant issues. Twenty-five forced-choice questions elicit any accidents affecting each area, functional impact at home and work (change of job or duties), duration of the problem, assessment by a health professional, and musculoskeletal problems in the last 7 days.

Pain will be analyzed by using the Visual Analogue Scale (VAS). VAS is a scale assessing pain intensity and composed of a horizontal or vertical line and anchored at both ends by words indicative of extremes of magnitude, such as "no pain" to "most intense pain sensation imaginable". In the current study, at the last 1 year and last 7 days, pain intensity was assessed by using horizontal lined VAS. Higher values show higher pain.
