Ergonomically adjustable laptop desk designed based on anthropometric characteristic of Mazandaran University of Medical Sciences students aged 20 to 30 years

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 include pain and pressure in areas such as wrists, elbows, neck and shoulders, along with The fatigue of these areas, especially back and waist pain, is common among many computer and laptop users. The purpose of this study was to design a customizable ergonomic table for use in laptops based on the anthropometric characteristics of Mazandaran medical students.
108 people including 61 males and 47 female students of Mazandaran University of Medical Sciences. 10 parameters include: 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, Elbow-fingertip length was measured using adjustable seating, caliper and meter. 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.
The mean age of subjects was 23 ± 3.14. Based on anthropometric characteristics, gold number, resulting percentiles and design equations, an adjustable ergonomic table was designed in three seated sitting, four-knee and Flower’s position.
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 more and more studies should be done in this regard.
