Relation between perceived and measured workload obtained by long-term inclinometry among dentists

Research output: Contribution to journalArticle


Dentists reported high perceived physical work conditions. Working postures and movements of the head and upper extremities during dental work were registered with inclinometry measurements during four hours. The aim was to clarify the relationship between measured working postures/movements and perceived physical work conditions. Dentists worked with elevated arms and a rather steep forward inclination of the head. Correlations (r = -0.52 to -0.66) between inclination velocity and perceived workload on VAS scales were found, but there were only weak correlations between observed working postures. The different tasks involved in dental work provide limited variation in work movements and postures, measured by inclinometry. By alternating between sitting and standing, it might be possible to achieve variation in physical workload during dental work. (c) 2008 Elsevier Ltd. All rights reserved.
