This also applies in particular to nursing activities with manual patient handling. In the present study a detailed investigation on the load of the lumbar spine during manual patient handling was performed. Methods For a total of 13 presumably endangering activities with transferring a patient the body movements performed by healthcare workers were recorded and the exerted action forces were determined with regard to magnitude direction and lateral distribution in the time course with a measuring bed a measuring chair and a measuring floor . By the application of biomechanical model calculations the load on the lowest intervertebral disc of the lumbar spine L5-S1 was determined considering the posture and action force data for every manual patient handling. Results The results of the investigations reveal the occurrence of high lumbar load during manual patient handling activities especially in those cases where awkward postures of the healthcare worker are combined with high action forces caused by the patient s mass. These findings were compared to suitable issues of corresponding investigations provided in the literature. Furthermore measurement-based characteristic values of lumbar load were derived for the use in statement procedures concerning the disease no. 2108 of the German list of occupational diseases. Conclusions To protect healthcare workers from mechanical overload and the
