Quantitative biomechanical analysis of wrist motion in bone-trimming jobs in the meat packing industry.
This study was motivated by the serious impact that cumulative trauma disorders (CTDs) of the upper extremities have on the meat packing industry.
To date, no quantitative data have been gathered on the kinematics of hand and wrist motion required in bone-trimming jobs in the red-meat packing industry and how these motions are related to the risk of CTDs.
The wrist motion of bone-trimming workers from a medium-sized plant was measured, and the kinematic data were compared to manufacturing industry's preliminary wrist motion benchmarks from industrial workers who performed hand-intensive, repetitive work in jobs that were of low and high risk of hand/wrist CTDs.
Results of this comparison show that numerous wrist motion variables in both the left and right hands of bone-trimming workers are in the high-risk category.
This quantitative analysis provides biomechanical support for the high incidence of CTDs in the meat packing industry.
The research reported in this paper established a preliminary database of wrist and hand kinematics required in bone-trimming jobs in the red-meat packing industry.
This kinematic database could augment the industry's efforts to reduce the severity and cost of CTDs.
Ergonomics practitioners in the industry could use the kinematic methods employed in this research to assess the CTD risk of jobs that require repetitious, hand-intensive work.
