Pedestrian safety is a current issue and the lower limb being widely injured during vehiclepedestrian crash, injury mechanisms of the lower limb are being investigated. Impact tests were conducted on isolated lower limb in order to reproduce pedestrian injuries such as ligament rupture and tibia fracture. Accelerometer signals were then processed using time scale analysis and a new injury criterion is defined, based on how transient the signal is. The criterion successfully discriminates ligament injuries from bone injuries and creates a way to get the chronology of the injury during an impact test on cadaveric specimen.
