Biomechanics and Orthopaedics

Research fields

LBMC’s Biomechanics & Orthopaedics team brings together complementary skills and expertise from researchers in biomechanics, mechanics and engineering, physiology, and clinics. This multidisciplinary research group aims at improving our biomechanical knowledge on the behaviour of the human musculoskeletal system, leading to applications dedicated to orthopaedics, sports medicine and functional rehabilitation, such as:

  • The design and evaluation of devices and clinical approaches (orthoses, prosthetic implants, computer aided surgical guidance)

  • The quantitative analysis of human motion and muscle function,

  • The biomechanical modeling of the musculo-osteo-articular system (multi-body and finite element methods),

  • The parameterization and personalization of numerical models from medical imaging.

Scientific methodology

In order to investigate the kinematic and dynamic behavior of human joints and segments, the Biomechanics & Orthopaedics team has been implementing for many years a combined approach based on in-vivo experiments and dynamic modeling of the human movement. This methodology focuses the research activities around the development and validation of:

  • Protocols and methods for reliable in-vivo measurements (specific data filtering, correction of soft tissue artifacts) dedicated to clinical investigation;

  • Numerical models to assess non-directly measurable parameters (e.g. joint loading, forces transmitted through ligaments and tendons, forces generated by muscular activity, pressures in articular cartilages, bone stress…);

  • Methods to take into account inter-individual variations, both in healthy or pathological subjects: 3D reconstruction of biological structures from medical imaging, scaling and identification of anatomical parameters (personalized shapes of bones, ligaments, muscles and articular contact surfaces) related to movement analysis, inverse dynamics and muscle activation computation.
