K�pergerechtes moving wants to be learned

An interview with painted Lenkeit, ergonomics advisor of the Dauphin human Design Group GmbH & CO. Kg, OffenhausenEin safe and healthy work surrounding field avoids occupational illnesses. Safety inspectors do not only follow this premise and - engineers, but also ergonomics advisor painted Lenkeit. A focus of its work is on the prevention and the associated sensitization from coworkers to the avoidance of false attitudes because of the job. Thus he dedicates himself to a phenomenon, which employs the working sphere in Germany: Although in the meantime approximately 17 million humans, nearly 20 per cent of all Germans, sitting in the office work, the occupational complaints, which were coined/shaped in former times more by manual labor, in the comparison changed not substantially. Sporadic or chronic back pain and spannings know today many office workers. The behavior of humans on the job on basis of scientific realizations to point out and change and it thereby to a body-contoured attitude and body-contoured moving animate, is the goal, which painted Lenkeit daily in Germany and abroad aims at. In the interview it describes, what its experience after in the context of the operational health management is meaningful, in order to make possible in the office a safe and healthy work surrounding field. They are daily in the office work worlds so called on the way. Which� are your realizations? The work worlds differ substantially. Current topics, which I focus in Germany and abroad with consultation, refer to correct handling the office equipment. In the center thereby the body-contoured attitude is located. Coworkers at the office workstation bend very strongly to a passive seat attitude, which not surprised, because one works the more concentrated, the less pay attention you to their behavior and/or their body attitude. If muscles then still permanent and on one side strained are or the spinal column are biomechanically strained � thus a static seat attitude is present � is already health-endangering those. My goal is it, hint and cheats for body-contoured sitting and moving at the office workstation to mediate. Here a substantial consulting need prevails also at well equipped offices. How do you use scientific realizations as an ergonomics expert, who co-operates closely with industrial safety experts and the work medical profession, with your work in enterprises? The ergonomics consultation has the goal of creating a safe and healthy work surrounding field. In the consultation I, basedly on scientific realizations, obtain the consequences of the loads with not body-contoured seat attitudes. We take an example from the current seat research. It is concerned with the biomechanical load of the spinal column of sitting humans. The results show that the load of the spinal column rises rapidly, the more the spinal column itself in sitting deformed, thus from their normal double S form deviate. The universitymedical mechanism of the Rheinland Westf�li technical university (RWTH) Aachen provided different studies in the last decade for dynamic sitting in the office. In the most current study with anatomical eddy models and digital angular measurements at test persons as well as videosupported recordings it could be proven that the basin tilting has a substantial meaning when sitting. It is the measure for the load and/or discharge of the spinal column. Standing humans have a basin angle of inclination of on the average 35�. The spinal column is exonerative in its ideal form and. That was the initial value, that the scientists� from Aachen for their study to reason had put. Numerous measurements prove that with horizontal seat face the basin back turn with approximately 22,0� is largest, i.e. the spinal column is strongly burdening. Even with a seat face of minus 4�, bent forward, the researchers observed still another strong basin back turn. Only starting from a seat angle of inclination of minus 8� it comes to the results of the researchers to a positive effect on the basin position in sitting, in the sense of a body-contoured putting of the spinal column up. Dr. Andreas beautiful, of the RWTH, summarizes the results in such a way: � you go to seats always as and stehst". All I let these realizations and also the knowledge from earlier studies flow into the ergonomics consultation. However without praying the many, important, numbers confusing nevertheless in the sum however then again and again down. How do you sensitize humans to examine their behavior? Body-contoured moving wants to be learned. Humans must experience, what determines the science in long research rows and theoretically well-foundedly. With it I do not mean that they must feel the pain, the false attitudes at the office workstation cause. Because then it is usually too late. I set in prevention. Clarifies, as preventive acting helps to remain permanently healthy and fit. My partner is the operational health management. Together with safety inspectors and safety engineers we integrate demonstrations, presence meetings and job committing into the existing operational measures. We have a large success with the scientific measuring procedures from our ErgoLab. With this ergonomic realizations, like those the RWTH, can be mediated in descriptive way. Thus we use the ErgoMouse for example on operational health days, in order the effect of the seat correct fit and - attitude out to point. In addition three measurements are accomplished: In the first measurement the spinal column of standing humans is documented by the head over the entire backs. The specific double S form of the spinal column of the test person becomes visible on a monitor. In a second measurement the spinal column in the seating position on the job, usual for the test person, is represented. Finally a measurement on an office chair with Synchro Activ balance takes place, thus with a seat face bent forward from up to minus 12� with synchronized backrest support. With the comparison of the results of measurement the participant sees that the seating position of the natural spinal column curvature measured last comes in standing very close. Thus it is clarified to it that a seat face of the premise bent forward " sits always as you go and stehst" very close comes. That has effect. The results of measurement are printed into a Ergopass, which the participant receives. The ErgoMouse is very in demand. A further Ergolab module is the Elektromyogramm (mini EMG). Thus safety inspectors have and - engineers the possibility workcaused muscle loads� to point out in the daily work. The mini EMG points muscle activities out within the range of the neck, neck and shoulder musculature as well as in the lower arm with workstations. � the Smily announcement � with traffic light function � thus green, yellow, red � indicates one-sided muscle demands in real time. Like that also a direct attitude correction is possible. The learning UHL eyeSeat is as it were a further member of the ErgoLab family. It serves the long-term observation of the seat behavior. Pressure sensors in seat and backrest document seat habits, refer the user to if it does not use the seat face correctly or permanently on the front edge sits or takes a static seat attitude. The moreover one has eyeSeat a statistics function, which documents the seat behavior of the user. From this measures for an optimized work place layout can be derived. We work at present to integrate a further measuring procedure into the ErgoLab. With this procedure we will visualize the entire body attitude on the job. Where we must as " B�roarbeiter" begin to optimize our seating position? So in a banal way it sounds: They must take and with the functions of your chair make themselves the operating instructions familiar. Therefore it belongs also to the tasks of safety inspectors and - to ensure engineers that all coworkers know, understand and use these. We made very good experiences to place at workstations operating instructions on-line the order. Then it cannot be moved. Beyond that one should know, where important notes to the correct fit are to be found. In the Internet easily comprehensibly hints are located. Thus the 60-Sekunden-Check on the homepage of Dauphin or with www.Menschen-und-Arbeit.de offers a fast possibility of analyzing and � if necessarily � of improving its own seat behavior. Mr. Lenkeit, we thank you for the discussion picture: Sitting with support of the arm rests or the table surface is better, because thus the spanning risk in the neck neck musculature is reduced.
