Introduction: The purpose of this study was to study the relationship between ergonomic of educational equipments with anthropometrical parameters and upper extremity abnormalities in primary school girl students in Mashhad.
 Methods: In this way, 14225 girl students were selected as statistical population, and then 375 subjects randomly were selected as a samples study. Some anthropometrical parameters as; popliteal height, popliteal-buttock length, elbow height from 90° angle, and shoulder height from setting position along with some educational equipments dimension used such as bench height, bench depth, desk height and width were measured. Moreover, upper extremity abnormalities including lumbar lordosis and thorax kyphosis were evaluated by flexible ruler. The related anthropometrical measures along with desk and bench dimensions also were determined in range of accepted limit (AL), over range of accepted limit and below range of accepted limit for each of benches and desks dimension. For statistical analysis the Chi-Square test in contingency tables, Cramer’s phi were used by SPPS version 16 (P<0/05).
Results: The result of this study indicated that the 81/8 percent of benches was higher than max accepted limit of the popliteal height, and 76/8 of students used some desks that was higher than max accepted limit (P<0/05). Bench depth was inappropriate for %100 of students and smaller than min accepted limit. Furthermore significant relationship observed between measure match bench height with popliteal height and abnormalities lordosis and kyphosis (p≤0/05).
Conclusion: The result of present study indicated that educational equipments of the Mashhad schools had no minimum ergonomic standard.
