Biomechanical Research

The RIH Orthopaedic Foundation provides the perfect setting for biomechanical research studies, particularly those utilizing cadaveric specimens. Successful execution of these studies requires meticulous planning and close coordination of activities. With integrated bioskills and mechanical testing laboratories, RIHOF streamlines project workflow and controls for critical test variables such as time, temperature, and handling.

Our unique setup also facilitates the iterative approach that is often needed when developing custom biomechanical test protocols. After test specimens are prepared in the bioskills lab, they are immediately brought into the adjacent mechanical testing lab for evaluation. By witnessing the testing and obtaining instant feedback, researchers can make adjustments as needed to refine their methodology. This ensures the efficient usage of resources and the achievement of optimal results.

In conjunction with the mechanical test lab’s load frames, RIHOF utilizes the following equipment and software to assess biomechanical properties and performance:

  • Optotrak Certus 3D Motion Capture System (Specs)
  • Kinovea 2D Motion Analysis Software (Specs)
  • Tekscan I-Scan Pressure Mapping System (Specs)
  • Scanco Medical MicroCT ScannerĀ (Specs)
  • Materialise Mimics 3D Medical Image Segmentation Software (Specs)

Prior Work

RIHOF has published biomechanical research studies in a number of high impact journals, including The Journal of Arthroplasty, Orthopaedic Journal of Sports Medicine, and The Journal of Hand Surgery.
