Introduction: In recent years, with the progressive development of various scientific, research and industrial fields, there are musculoskeletal disorders in computer and laptop users. Musculoskeletal disorders including pain and pressure in areas such as wrists, elbows, neck and shoulders, along with the fatigue of these areas, especially back and waist pain are common among many computer and laptop users. The aim of this study was to design a customizable ergonomic table for using laptops based on the anthropometric characteristics of students of Mazandaran University of Medical Sciences.
Methods: This study was conducted on 108 (61 males and 47 females) students of Mazandaran University of Medical Sciences. Ten parameters including knee height sitting on a chair, eyes- elbows height, cross-legged posture kneeling length, cross-legged posture kneeling height, thick thighs, elbow rest height-sitting, shoulder-fingertip length, abdominal depth, hip breath, and elbow-fingertip length were measured using the adjustable seating, caliper and meter. The SPSS software version 20 was used to analyze the data. Then, the percentiles 1 to 99 and the golden number 1.618 were used to design the table.
Results: The mean age of the subjects was 23 ± 3.14 years. Based on anthropometric characteristics, gold number, resulting percentiles and design equations, an adjustable ergonomic table was designed in three seated sitting, four-knee and Fowler’s positions.
Conclusions: It is expected that after putting this device on the laptop, the musculoskeletal disorders caused by its use will be reduced. Because of limited studies have been conducted in this area, it is suggested that further studies in this regard be undertaken in the future.
