Background: Laptops are not ergonomically being designed as the same as a desktop computer and are not suitable for prolonged use. The current study aimed to assess the different postures laptop users, especially in non-official places, and its effect on musculoskeletal disorders (MSDs). Study Design: This was a cross-sectional study. Methods: One hundred and fifty university students were chosen that have continuous use of laptop for 5 years. Data were gathered by questionnaire (demographic data, laptop use-related questions and visual posture questions) and posture analysis using Rapid Upper Limb Assessment method. T-test, Chi-square and Spearman correlation coefficient tests were used in data analysis. Results: The mean of body weight in males and females was 77.58 ± 13.34 kg and 62.35 ± 10.67 kg, respectively. Two postures, including E (sitting on the sofa and put the laptop on the table) and F (sitting and working on an office chair and desk), were the most current postures by the users. Postures M and K had been as the most inappropriate postures, while postures D and G were defined as postures that are more appropriate. Conclusion: Laptop is using frequently as a popular device at home, dormitory or other non-official places. Due to nature of these places and inherent characteristics of laptops, it is not possible to make it adjust for the body based on ergonomic principals. Neck, upper and lower back, shoulder and wrist are organs that influence more by laptop based on body configuration.
