3. Work station characteristics: 3 Lighting Fatigue Long work hours Visual overload Un-natural sitting position Arm position Eating at the computer

4. Goals of the research: To test the effectiveness over time of an innovative self-modeling photo-training method for reducing musculoskeletal risk among workers at computers. This was compared to traditional one-time ergonomic training (pamphlets, personal advice and workstation adjustments). 4

5. Method for Ergonomic Estimate of Posture RAPID UPPER LIMB ASSESSMENT (RULA)  Scale from 1-7 (1 good posture – 7 poor posture)  RULA takes into account a series of angles and deviations 5 Additional aspects

6. Description of the Experiment 60 workers (51 from BGU and 9 from Soroka Hospital) working in different jobs (e.g. administration, research, programmers) Age range 26-66 38 Women and 22 Men At each participant’s work station a webcam was installed that photographed at random intervals approximately each 20 mins. 10-15 photos were analyzed each day Three study groups:  Photo-training with personalized pop-up photos (intervention)  Traditional office training  Control 6
