This study examined the changes of the hip, knee and ankle joint kinematics after a wedged insole application for children with flexible flatfoot. The results showed that insole significantly decreased maximum calcaneal eversion velocity and maximum internal tibial rotation angle in children with flexible flatfoot. ConclusionsThe wedge-designed insole may be beneficial to children with flexible flatfoot by decreasing the imposed joint loading and preventing further lower extremity injuries. SummaryThis study presented the characteristics of the loading impact on the residuum of a transfemoral amputee fitted with an osseointegrated fixation during a fall for the first time. The maximum force (1145 N = 132% of the body weight and moments (153 N m) were applied on the long and medio-lateral axes, respectively, approximately 0.85 s after heel contact of the prosthesis. ConclusionsThis study provided valuable information (e.g., magnitude of loading at impact, sequence of falling events and duration of key phases) that can be used to design protective equipment and to refine design of osseointegrated fixation.
