An ergonomic evaluation of grain picking activity of farm women

P. Parimalam, J. Meenakshi


A study on an ergonomic evaluation of the grain picking activity of women using
conventional and improved grain picker was conducted in Madurai district of Tamil
Nadu. Twenty women workers were made to perform grain picking activity by
conventional and improved method. Data on time and work study, physiological
parameters, hand grip strength and musculo-skeletal disorder of the women were
collected. The results revealed that the improved method of grain picking activity
showed high picking efficiency (66.86%), minimum reduction in grip strength of right
hand (17.52%) and reduced physiological cost of work (19) when compared with
conventional method of grain picking.
