Abstract
The aim of this study is to conduct akinematic analysis of occupational posture in orthodontists. Arepresentative sample of21 (13female/8male) residents in orthodontics and orthodontists was studied. The CUELA system collects kinematic data of the occupational posture. Alongside the kinematic analysis, the tasks performed on-site were also subject to adetailed computerized analysis. Data analysis comprised the evaluation and comparison of joint angle distribution in accordance with ergonomic standards categorized as neutral, moderate or awkward posture. The most common activities were executed in aseated position. During "treatment" (28% of total time) participants most often worked with astraight back (84.7%), whereas a"bent or twisted" torso posture was observed 23.4% of the time. For head and cervical spine, the 75th and 95thpercentiles presented worse (higher) values during treatment as compared to non-orthodontic activities. The seated position next to the patient during treatment showed astronger inclination of the thoracic spine to the right and an inclination of the lumber spine to the left. Orthodontists do take characteristic postures during treatment activities with highest angle values. The postures differ in the area of head and cervical spine with regard to the various activities carried out in the 3categories.
