Análisis de riesgo ergonómico inherente a la actividad del baño de neonatos desempeñada por enfermeras utilizando la metodología REBA a través de sensores de profundidad Kinect

Abstract

The absence of quantitative parameters to determine the mobility of the body segments required by functional assessment scales such as REBA (Rapid Entire Boddy Assessment) reduce its reliability by identifying risks based only on postural observation. The present work analyzes the ergonomic risk associated with neonatal bathing activity performed by nurses, the influence of the introduction of Kinect sensors and their marker-less skeleton tracking function in conjunction with the postural analysis tool REBA to reduce the inter-observer variability and the subjectivity of the results. 5 participants without injuries reproduced the sequence of movements of a baby's body wash task, selected as the most critical within the activity. The use of a reference motion capture system (photogrammetry) was used to check the validity of Kinect as a measurement instrument and its precision. Variables such as the recording frequency of the sensors, and their location with respect to the participants, influence the

detection of body positions. The analyzed posture is associated with an intermediate level of ergonomic risk and requires intervention.
