A critical review of biomechanical, epidemiological, physiological and psychophysical criteria for designing manual materials handling tasks

摘要

For over four decades, individuals from various disciplines have extensively researched the tasks comprising manual materials handling (MMH): lifting, lowering, pushing, pulling, carrying and holding. The primary motivation for these research efforts has been a desire to understand human capabilities so hat tasks can be designed such that the demands of the task are at or below the capacities of the workers performing the task. Various criteria for defining acceptable task demands have been developed from the principles of biomecha- nics, physiology, and psychophysica.
