Abstract
A systematic review of the literature reported by van Eerd and his colleagues in this issue of the Journal [ [1] Van Eerd D. Beaton D. Cole D. Lucas J. Hogg-Johnson S. Bombardier C. Classification systems for upper-limb musculoskeletal disorders in workers: A review of the literature. J Clin Epidemiol. 2003; 56: 925-936 Abstract Full Text Full Text PDF PubMed Scopus (61) Google Scholar ] uncovered a cacophony of classification systems for upper limb musculoskeletal disorders in workers. No doubt such diagnostic variability impedes progress in testing putative causal associations let alone purative therapeutic or preventive interventions. Such an observation is a clarion call for a carefully honed nosologic classification of the subgroups of workers afflicted with these disabling conditions. There is a corollary literature than could well inform such an exercise.
