Can visual perception be used to estimate body part angles

Article Abstract:

Research was conducted to examine the errors in estimating postural angles from a videotape. Twenty engineering students were asked to report perceived angles as displayed. Observational method is contingent on the analyst's occular judgement to identify various body posturs. Subjects were inclined to exaggerate the true postural angle in the low range (1-60 degrees) and slightly underestimate the actual angle in the medium (61-120 degrees) and high angle ranges (121-180 degrees). Awkward body postures result in pain and musculoskeletal aberrations.

Active microbreak effects on musculoskeletal comfort ratings in meatpacking plants

Article Abstract:

A study of the effect of incorporating active microbreaks during working hours in meatpacking plants on 28 employees reveals that microbreaks decrease the musculoskeletal discomfort developed during working hours. The discomfort depends on the strength and background of the employees, with the Caucasians feeling greater discomfort that the Hispanics.
