Spinal Biomechanics Laboratory

Spine Simulator with Custom-Built Capabilities

Our all new, custom-built, multi-axis spine simulator (PizzaCake Industries) is cutting-edge and advanced. It is capable of delivering answers to many research questions pertaining to spinal biomechanics. It can simulate cervical, lumbar, full torso, and pelvis / sacroiliac motion and deliver high-precision data.

The simulator has the following capabilities:

  • Full protocol customization (LabVIEW; National Instruments)
  • 6 DOF load cell (Omega 160; ATI Technologies)
  • 6 DOF mobility (translations / torques) provided by Arcus PMX-4EX-SA stepper motors
  • Air cylinders (Airpel; Airpot Corp.) for application of axial compression / distraction or muscle loads
  • Analog output / input
    •  Signal acquisition from extensometers, DVRTs, pressure sensors, etc.
  • Digital output
  • Full 3D motion kinematics (OptiTrack)

Our research capabilities are open and available to all industries, private or public. Please contact us to discuss your project needs.
