“…Compared with objective measurements of the physical work environment or biomechanical loads, the questionnaire technique is much cheaper and gives roughly similar results for several variables. Subjective estimates of the effort required in manual materials handling reflect the individual perception of the amount of physical and motivational resources required to meet the demands imposed by the physical task (20). Comparing data obtained by self-administered questionnaires with results from observation studies, Viikari-Juntura et a1 found lifting and canying to be reported less often than they were observed, while the adoption of forward bent postures was reported more frequently than it was observed.…”

Objectives The purpose of this study was to determine the occupational factors that cause workers to take sick leave attributed to low-back pain. Methods Twice, with a 24-month interval, 117 white-and 189 blue-collar employees from 2 metal industry companies completed a questionnaire on recurrent low-back pain and exposure to potential risk factors (biomechanical loads, physical environment, psychosocial factors) at work. Sick leave was monitored for the period between the questionnaires. Results Low-back pain was predicted by exposure to harmful biomechanical loads among both white-and blue-collar workers [odds ratio (OR) 4.1 and 4.7, respectively), stress among white-collar workers (OR 2.4), and draft among blue-collar workers (OR 2.3). The take-up of sick leave was predicted by exposure to harmful biomechanical loads [rate ratio (RR) 1.71; for sick leaves attributed to low-back pain the rate ratio was 3.1. Lack of recognition and respect at work predicted sick leave attributed to low-back pain (RR 2.0), but not sick leave attributed to other disorders. CO~CIUS~OIIS Recurrent low-back pain is preceded by reports of harmful biomechanical loads at work among white-and blue-collar workers, by stress among white-collar workers and by draft among blue-collar workers. The environmental and psychosocial factors under study did not modify the relation between biomechanical loads and recurrent low-back pain. Sick leave attributed to back disorders is preceded by exposure to biomechanical loads at work and by a lack of recognition and respect at work among blue-collar workers. Biomechanical loading seems to be the most important occupational factor predicting both recurrent low-back pain and sick leave attributed to back disorders. Lack of recognition and respect at work appear to affect sick leave attributed to back disorders.

“…Starting with a very light or heavy load weight, a worker performs lifting and subjectively adjusting the load weight repeatedly until arriving at what he/she perceives as the maximum weight that can be safely handled for an 8-h work shift. The key assumption in this approach is that during a lifting trial, an individual can subjectively determine a load weight's acceptability by integrating and interpreting the information received from the nerve endings and sensor organs in the cardiovascular, musculoskeletal and pulmonary systems (Herrin et al 1986;Gamberale, 1990).…”
