• Description:
  The objective of this study was to develop and validate a new methodology for characterizing the human arm's response to impulsive pulling forces based on a single degree-of-freedom, second-order, linear model. Such forces are encountered while operating right-angle torque tools, and are thought to pose a risk of injury. Previously published research involved human testing in which subjects, instructed to stabilize an underdamped mechanical system released from a non-equilibrium initial position, were subjected to an oscillating torque input. This task differs from using a torque tool where the input is an impulsive torque with typical durations of 35 - 1000 ms, depending on stiffness of the fastened joint. Because human arm viscoelasticity is task-dependent, the new parameter assessment method was designed to more closely mimic right-angle torque tool operation. Testing was conducted with experienced torque tool operators. Effects of gender and working posture were examined. [Description provided by NIOSH]
