Reid, Christopher R., McCauley-Bush, Pamela, Karwowski, Waldemar and McMullin, Dianne L. (2009): The Need for a Lower Extremity Risk Assessment Model. In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 887-891.

Current ergonomic risk assessment tools do not assess possible occupational (extrinsic) and personal (intrinsic) risk factors for the lower extremity regions of employees. This document proposes that it is possible to develop a lower extremity risk assessment (LERA) model for quantifying such risks. A literature review was conducted for work-related musculoskeletal disorders of the lower extremity that affect the nervous, muscular, vascular, and skeletal systems. This initial model of LERA was developed using epidemiological literature and subject matter expert opinion specifically for the knee joint and is considered a preliminary step towards quantifying the etiology of cumulative occupational knee disorders.

McMullin, Dianne L. and Hallbeck, M. Susan (1992): Comparison of Power Grasp and Three-Jaw Chuck Pinch Static Strength and Endurance between Industrial Workers and College Students: A Pilot Study. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 770-774.

Due to the ease of obtaining subjects, much ergonomics research utilizes students. However, is it valid to make a hypothesis concerning industrial workers from this student data? To evaluate the validity of such a generalization, ten industrial workers and ten students, five men and five women from each subject sample participated in the study. The functional range of motion for extension and flexion in the wrist and anthropometric measurements of the hand and arm were measured for each subject. In addition, the three-jaw chuck pinch force and endurance and power grasp force and endurance were also measured. The data was analyzed using both paired comparisons and ANOVA tests. Only power grasp force showed a strength difference between students and industrial workers. The students had 82.9% of the grasp force of the industrial workers.
