Context and Objectives
Musculoskeletal pathologies have multiple causes (trauma, neuromuscular, and degenerative). It impacts the patient’s daily life by limiting the movement of their locomotor system and severe pain is often coupled with. In this framework, the motion analysis is of great interest for several applications: in functional rehabilitation to detect any impairment and understand it, in orthopedic surgery to diagnose a pathology or to acquire essential data during an assisted surgical procedure. In these cases, optical markers are often used and placed either on the skin to avoid any incision or directly on the bone structures during surgery. An optical camera system is then used to locate these markers and thus determine the position of bone structures during a motion.
These solutions involve very sophisticated systems (as VICON) but they remain expensive, not versatile, and the accuracy at the joint level is not sufficient due to soft tissues artefact.
In order to tackle the problem, the project’s objective will be to design and implement an innovative and portable solution, based on the markerless methods of the literature. The main joint concerned will be the knee. Two main technical issues to be solved:
Three outputs are expected for the project:
