The extent to which physical differences in two specific jobs can be reflected in actigraph data was examined. Actigraphs were affixed to the wrists and ankles of workers to determine if changes in activity levels paralleled activity differences noted through direct observation and videotape analysis. The two jobs studied were grocery cashiers and general merchandise clerks. Ten grocery cashiers and four general merchandise clerks participated in the study. Data were collected over an 8 hour period. Clear differences in the activity patterns were recorded for the two workers. The high levels of wrist activity and low levels of ankle activity recorded by the cashier differed from the moderate levels of wrist activity and high levels of ankle activity recorded by the clerk. The authors conclude that actigraphy provided some advantages over traditional observational methods for quantifying work related hand/wrist activity. However, they also note that in most cases the quantitative facts determined from the actigraphic measurements need the qualitative determinations from visual observations made during the work study.
