Recent developments in computer assisted surgery offer promising solutions for the translation of the high accuracy of the preoperative imaging and planning into precise intraoperative surgery. Broad clinical application is hindered by high costs, additional time during intervention, problems of intraoperative man and machine interaction, and the spatially(More)
Intermittant long-term stimulation of fast rabbit muscles up to 28 days with a frequency pattern resembling that of a slow muscle (10 Imp/sec) led to a slowing of the time course of contraction already during the first week. There was an increase of tetanic tension as well. The observed rearrangement of activities of key enzymes of energy supplying(More)
Some effects of isometric exercise were studied in fast rectus femoris muscle and slow soleus muscle of the male rat. Isometric twitch contraction time did not change in both muscles, however, maximum tetanic tension increased in the fast muscle. Changes in the enzyme activity pattern of energy supplying metabolism of the rectus femoris muscle consisted in(More)
The introduction of minimal invasive operating techniques into the conventional surgical worksystem, requires a fundamental analysis of the resulting problems. Based on ergonomic investigations, concerning working postures, static holding work and task sequence analysis, bottlenecks of workplace design can be demonstrated. As a contribution to the(More)
Operational interventions can be planned and simulated accurately with the help of a three-dimensional reconstruction of the anatomical bone structures, created from the tomographic data of a patient. Computer-assisted navigation systems or robotic systems can assist the intraoperative realization of the planned intervention and may support the spatial(More)
Effects of a three weeks lasting short-term, high intensity training (sprint training) upon contractile parameters and selected enzyme activities of energy-supplying metabolism in slow soleus and fast rectus femoris muscle were investigated in female rats. Isometric twitch contraction time decreased in the soleus muscle. Maximum tetanic tension was found(More)
