A model for assessing the probability of musculoskeletal disorders depending on biomechanical and personal risk factors

The aim of the project was to develop - in the form of a mathematical model - a relationship between personal factors, and biomechanical and psychosocial risk factors of musculoskeletal load and the probability of developing musculoskeletal disorders.As a result of the project:- a database was developed with cases of musculoskeletal disorders related to personal risk factors (gender, age, years of work, etc.) and risk factors related to the working environment that describe posture, exerted force, time sequences and psychosocial factors;- work tasks related to the greatest risk of developing musculoskeletal disorders were selected;- experiments were conducted; on their basis load and fatigue of selected body regions during work tasks that posed a high risk for developing musculoskeletal disorders were determined;- a mathematical model was developed for assessing the probability of developing musculoskeletal disorders;- a computer program was developed for assessing the probability of developing musculoskeletal disorders; the results of experimental studies were used in testing selected cases.
