Ergonomic Analysis Of A Hair Salon, Joseph Keebler, David Schuster, Scott Ososky Jan 2008

Ergonomic Analysis Of A Hair Salon, Joseph Keebler, David Schuster, Scott Ososky

Publications

Cosmetology involves a number of diverse tasks that have been implicated in cumulative trauma disorders and in other workplace injuries. This case study presents an analysis of injury risk and prevalence in a salon. Individual, occupational, and organizational factors are considered, and potential areas where risk can be reduced are presented.

During a lifting task the movement of the trunk can account for the majority of the external moment about the ankle. Though the angle of trunk flexion and the external moment about the ankles are roughly correlated, this correlation can be reduced by various segmental dynamics and momentums with the upper/lower extremities. Two methods are proposed in this technical note for describing the relationship between the kinematics and the kinetics of a lifting motion. The first relies on the phase plane analysis technique and explores the relative phase angle between the kinematic characteristics of lifting motion (i.e., trunk ...
