Do repetitive tasks give rise to musculoskeletal disorders?
Repetitive tasks can undoubtedly cause discomfort and pain, but whether they cause or worsen the pathology causing the pain is most uncertain. Research in this area is difficult as the work-related upper limb disorders do not occur exclusively in workers and because there is no simple, reliable and reproducible test for most work-related upper limb disorders . Furthermore many studies are difficult to interpret as they detect disease by the presence of symptoms: one would expect manual workers to complain of more symptoms than sedentary workers and symptom aggravation does not tell one anything about the causation of the underlying pathology.
