An ergonomic assessment of the airline baggage handler

48took place at the beginning of this study, which seemed to be more efficient. Having thesubjects of the experiment complete a survey at the beginning of the experiment allowsthe subjects to base their conclusions on actual perceptions experienced and acquiredthrough their work experiences as oppose to drawing conclusions on what they might feelto be the right answer(s) based on trails of the experiment. Once the experiment is done,input can then be gathered to find out which factors and variable were the most effectivefor the subject(s).A limitation of this study was how it dealt with the physiological part of theexperiment. Only three subjects were tested. Additionally, nothing was stated about theage of the test subjects. The sample size of the survey participants was not clearly statedin the experiment, leaving one to wonder and guess at how big the participation level ofthe baggage handlers were. There was one reference to 67 baggage handlers commentingon the prevalence of musculoskeletal symptoms. Having a sample size of three subjectsleaves the experiment open to criticisms of population bias. Also the lack of a controlgroup made it impossible to compare the validity of the results purposed by the isolatedsample population.Ignoring these factors the results from this evaluation seem promising, and didgather conclusions that appeared to be noteworthy in reducing musculoskeletal problemsfor baggage handlers associated with their work environment.
