title: [Number of complaints in cashiers at workplaces with conventional cash registers and those with barcode reader equipment].
abstract: 115 cash register operators of supermarkets have been studied. Postural complaints are high, compared to office workers. The results obtained by questionnaire and by a rheumatological examination revealed that most cash register operators complain about pains in the back, in the left shoulder and in the left arm. The cashiers working on laser-scanner-systems have the same complaints, but they have significantly less pains in the right arm and the right hand because the cash register is only used infrequently. It seems to be better if cashiers have to do different tasks in a supermarket because the study shows that cashiers who work at different workplaces have significantly less pains then those who work only at the cash register.
