For example, in a movement in which the subject lifts an arm, the code of the arm position changes when the elbow reaches the level of the shoulder. Postural load and back pain of workers in the manufacturing of prefabricated concrete elements.
Risk prevention and control strategy for upper limb musculoskeletal disorders. Click Figure to enlarge Figure 4: To get the postural risk level it is necessary to classify the positions of ergonomiz back, shoulders and legs.
Informe Final Ergonomía – Método Rula
The bending of the legs is calculated by measuring the angle formed by the line connecting the hip to the knee and the line connecting the knee to the ankle.
In order to play the sequence of movements always in the same way, we showed each posture to the player in a screen.
Figure 8 shows the estimated total percentages of right coded and right categorized postures.
Based on metdo body position code OWAS identifies four rla which reflect static load risk degree Mattila and Vilki, Future research may consider attaching markers to the load, and using the depth sensor and video camera data to track these additions and achieve automatic load detection Clark et al.
Click Figure to enlarge Figure 1: This meant that the number of observations in each sequence was different and consequently comparisons between the different positions of the sensor could be somehow affected.
Contingency table of legs metkdo classifications that were obtained by experts and Kinect. Automatic load detection would be desirable if the load handled by the worker greatly varies over the course of his work. Unlike direct methods, observational methods have limitations in the sampling rates.
Comparison of self-report, video observation and direct measurement methods for upper extremity musculoskeletal disorder physical risk factors.
Analysis of working postures in hammering tasks on building construction sites using the computerized OWAS method. However, the use of photographs or videos in the observational methods also presents drawbacks. In addition to depth Depth data and color data RGB datathe sensor provides information about the position of the joints of recognized users present in the frame skeleton data metodi close to real time.
The postures that the experts classified in different manners were then analyzed again to reach a consensus on the score.

Values must be in the range 0 through 1. The results of this work will show that this is an important drawback in using Kinect to assess postures in a real work environment. European Agency for Safety and Health at Work, Then the results obtained are compared with those obtained by human observers and finally the ruula conclusions are summarized. The risk category of each posture was correctly classified by the sensor in The evaluator makes observations at regular intervals of 30 to 60 seconds coding each posture according to the digits shown in Figure 2, and an additional fourth digit depending on the load handled by the worker.

The frontal plane is calculated as a vertical plane which passes through both hips 12 and However, the edgonomia of frequency, or time variation of risk, requires the use of devices with high sampling rates A. How to cite this article.

They are also easy to use, do not require complex calibration processes and do not affect the work process. Click Figure to enlarge Figure 2: Current techniques for assessing physical exposure to work-related musculoskeletal risks, with emphasis on posture-based methods. It is necessary to remark that hip center is the joint 0 shown in Mrtodo 1, and it does not represent the true anatomical hip joint center. Kinect was initially developed for use in computer games, achieving a natural interaction with the user.
Occupational environmental medicine 55, — Springer Fachmedien Wiesbaden, Wiesbaden, pp. Coordinate system of the depth sensor. Assessment of work postures and movements using a video-based observation method and direct technical measurements. On the other hand, the percentage of wrong coded postures among no inferred postures could be different too.
