Task design, psycho-social work climate and upper extremity pain disorders – effects of an organisational redesign on manual repetitive assembly jobs

Are psychosocial factors, risk factors for symptoms and signs of the shoulder, elbow, or hand/wrist?: A review of the epidemiological literature

“…This implies that there is a high potential for integrated preventive approaches and although adequate interventions may not be easily accomplished, it certainly is an attractive option and a challenge to effective occupational health [Christmansson et al, 1999;Torp et al, 1999; National Research Council and the Institute of Medicine, 2001].…”

Explicit and implicit theories of change when designing and implementing preventive ergonomics interventions – a systematic literature review

“…However, it had a positive effect in another company where the break scheme complied with work routines. Christmansson et al (98) reported an aversion among assembly workers to a job enlargement intervention because they were not properly introduced to their new tasks. An illustration of the fact that better knowledge may not necessarily lead to improvements was reported in a study of slaughterhouse meatpackers (99).…”

“…Referring to a specific theory, but vaguely explaining how the intervention relates to that theory N=1 (58) Referring to a specific theory; strategy for implementation firmly rooted in theory N=12 (17,57,59,64,(77)(78)(79)(80)(81)(82)(83)(84) No reference to a change theory, and no reference for the intervention strategy either N= 4 (87,88,90,96) Referring to results from previous research, but not stating a particular theory of change N=13 (66,85,86,89,(91)(92)(93)(94)(95)(97)(98)(99)(100) Intervention strategy …”

Are changes in mechanical exposure and musculoskeletal health good performance indicators for primary interventions?

“…Psychosocial factors (Christmansson et al 1999;Fredriksson et al 2001;Johansson et al 1993;Wahlstedt et al 2000) and organisational factors (Demure et al 2000;Lagerstro¨m et al 1998;Silverstein et al 1988) also played an important confounding role in the efficacy of primary interventions. In two studies, unexpected or- ganisational changes interfered negatively with the intervention (Demure et al 2000;Lagerstro¨m et al 1998).…”
