Abstract
Ultrasound examinations may require sonographers to adopt unnatural postures which can lead to musculoskeletal disorders We previously assessed the effect of a vertical operation panel on muscular stress In this study we focused on the horizontal positioning of the control panel of a diagnostic ultrasound system to quantitatively assess the influence of work plane position on musculoskeletal stress during scanning Five subjects were asked to perform a simulated scanning task that involved touching five points on the control panel with the work plane set at different positions in space Electromyograms of each part of the body and wrist joint angles indicated that the least stressful position of the left hand was about 350 mm from the center of the trunk in the longitudinal front–back direction and 100 mm left of the center of the trunk in the lateral right–left directionAll procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation institutional and national and with the Helsinki Declaration of 1975 as revised in 2008 Informed consent was obtained from all patients for being included in the study
