Brief Summary

The goal of this observational study is to learn if a combination of postural exercise programs and ergonomics education can provide protective and therapeutic effects against work-related musculoskeletal disorders (WMSDs) in academic and administrative office staff at Bahçeşehir University (aged 20-55, working at least 3 months in an office setting). The main questions it aims to answer are: Does a 6-week program of ergonomics training and regular posture exercises reduce the frequency and severity of musculoskeletal pain? Can structured ergonomics education improve the alignment of the office environment with international safety standards (OSHA)? Is there a measurable improvement in the sleep quality of office workers following these interventions? Researchers will compare the pre-intervention baseline data to post-intervention results (after 6 weeks) to see if the interventions lead to a statistically significant reduction in physical discomfort and an increase in ergonomic compliance. Participants will: Undergo a comprehensive baseline assessment, including the Cornell Musculoskeletal Discomfort Questionnaire, New York Posture Analysis, and Pittsburgh Sleep Quality Index (PSQI). Attend a one-day intensive training program covering both theoretical ergonomics and practical postural exercises. Receive an instructional brochure with a QR code providing access to exercise videos.Perform the prescribed ergonomic adjustments and exercises during workdays for a duration of 6 weeks.Complete a follow-up assessment after 6 weeks to evaluate changes in pain levels, posture, and environmental compliance.

Outcome Measures

Primary Outcomes (3)

• Cornell Musculoskeletal Discomfort Questionnaire (CMDQ)

  CMDQ was developed by Alan Hedge and colleagues at Cornell University to evaluate the frequency, severity, and functional impact of discomfort across 11 body regions (Hedge et al., 1999). Scoring involves a weighted calculation where frequency, severity, and interference values are multiplied to produce a total score (0-90). The Turkish validity and reliability of the scale were established by Erdinç (2011).

  Baseline and post-intervention (6 weeks)

• New York Posture Analysis (NYPA)

  NYPA is an observational tool used to grade postural alignment in 13 body segments (McRoberts et al., 2013). Each segment is scored 1, 3, or 5, with total scores ranging from 13 to 65. It provides a standardized categorization from "Very Poor" to "Very Good."

  Baseline and post-intervention (6 weeks)

• Pittsburgh Sleep Quality Index (PSQI)

  The PSQI measures subjective sleep quality over a one-month interval through seven sub-dimensions (Buysse et al., 1989). The total score (0-21) distinguishes between "good" and "poor" sleepers. The Turkish version's psychometric properties were validated by Agargun et al. (1996).

posture exercises and ergonomic education

EXPERIMENTAL

Following baseline assessments, participants attended a one-day intensive training program. The curriculum integrated: Theoretical Education: Principles of office ergonomics and risk factors for work-related musculoskeletal disorders (WMSDs). Practical Training: Guided sessions on postural exercises and ergonomic workstation adjustments. Support Materials: Participants received a brochure summarizing the training. A QR code was provided for mobile access to instructional exercise videos. Participants were instructed to implement the ergonomic modifications and perform the exercises daily during work hours for a period of 6 weeks.

Behavioral: Exercise

Interventions

Exercise BEHAVIORAL

Digitalized Continuity via QR Code Technology: To bridge the gap between training and daily habit formation, the intervention utilizes custom-designed brochures embedded with QR codes. These link directly to high-quality video demonstrations, allowing participants to access professional guidance at their workstations in real-time, thereby reducing the "forgetting curve" typical of one-time trainings. Specific Academic/Administrative Context: While many ergonomics studies focus on industrial workers, this study specifically targets the unique stressors of a university setting (e.g., prolonged periods of intense cognitive load combined with static computer use among high-level education professionals). Comprehensive Outcome Mapping: The study is unique in its holistic evaluation, correlating physical posture (NYPA) and musculoskeletal pain (CMDQ) with environmental compliance (OSHA) and physiological recovery markers (PSQI Sleep Quality), offering a 360-degree view of the office worker
