Pooling data from different epidemiological studies of musculoskeletal disorders
(MSDs) is necessary to improve statistical power and to more precisely quantify
exposure-response relationships for MSDs. The pooling process is difficult and
time-consuming, and small methodological differences could lead to different
exposure-response relationships. A sub-committee of a six-study research
consortium studying carpal tunnel syndrome: (i) visited each study site, (ii)
documented methods used to collect physical exposure data and (iii) determined
compatibility of exposure variables across studies. Certain measures of force,
frequency of exertion and duty cycle were collected by all studies and were
largely compatible. A portion of studies had detailed data to investigate
simultaneous combinations of force, frequency and duration of exertions. Limited
compatibility was found for hand/wrist posture. Only two studies could calculate
compatible Strain Index scores, but Threshold Limit Value for Hand Activity Level
could be determined for all studies. Challenges of pooling data, resources
required and recommendations for future researchers are discussed. PRACTITIONER
SUMMARY: There is a need for standardised measures and measurement protocols of
physical exposure for the upper extremity. This study may provide guidance for
those planning to conduct an epidemiological study on quantified job physical
exposures, or planning to merge physical exposure data from similar studies with
some methodologic differences.
