...) minimize wear debris, (6) withstand typical loads in the lumbar spine, (7) avoid fatigue failure, and (8) be manufacturable. Performance metrics were then developed to objectively evaluate the design's success in meeting these criteria based on ASTM standards, comparative benchmark performance of total...

... including coordinated control of multiple degrees of freedom (DOF) and enhanced fidelity that to date have not been fully utilized. Previous robotic efforts in spine biomechanics have largely been limited to pure displacement control methods and slow quasi-static hybrid control approaches incorporating only...

...Nicolas V. Jaumard; Robert C. Richards; Susan M. Stagg-Williams; Elizabeth A. Friis, Ph.D. Surgical treatment interventions for low-back pain are increasing. Surgical risk associated with new techniques can be reduced by practice on synthetic spine replicas. However, current models for surgical...
