Multi-Axis Biomedical Testing Machines

Simulation of human joint motion for the purpose of testing and evaluating prosthetic devices prior to clinical deployment is essential to assure the successful outcome of such surgical procedures. AMTI’s multiaxis simulator machines provide the ideal environment for in-vitro wear, fatigue, and usability testing on a variety of prosthetic joint components.

AMTI simulator products include the latest innovative developments in technology:

Activities of Daily Living - increased forces and ranges of motion simulating a more real life test, eg. walking up and down stairs, getting out of a bath, squatting to pick something up and running and even swinging a golf club.
Virtual Soft Tissue Control software model for the replication of in vivo kinetics and kinematics during movement. The VST accurately accounts for the influence of soft tissue constraints surrounding the knee. The VST control system opens up a number of exciting new research opportunities in simulation and kinematic study of TKR performance. Soft tissue modelling can be used to create a variety of surgical conditions such as cruciate sacrificing and cruciate sparing procedures. The effects of alignment, mal-alignment and ligament balance can also be investigated.

Adaptive Control Technology, a breakthrough in simulator ease of use and dramatic reduction in tuning time from days to minutes. The ACT control system is enabled by a press of a button and within thirty or forty cycles of motion the RMS error is reduced to a level not obtainable with manual tuning.
Improved Tracking performance in both force and displacement control modes of operation conforming to ISO and ASTM standards.
Microseparation to simulate laxity in the constraining tissue of the hip (where appropriate) during the swing phase of gait.
