DOI: 10.1016/j.clinbiomech.2017.02.004
Abstract: Background: Anterior cruciate ligament reconstruction is associated with early onset knee osteoarthritis. Running is a typical activity following this surgery, but elevated knee joint contact forces are thought to contribute to osteoarthritis degenerative processes. It… read more here.

DOI: 10.1017/s0373463321000631
Abstract: Abstract Pedestrian dead reckoning (PDR) is widely used in handheld indoor positioning systems. However, low-cost inertial sensors built into smartphones provide poor-quality measurements, resulting in cumulative error which consists of heading estimation error caused by… read more here.

DOI: 10.1080/14763141.2023.2218325
Abstract: For adults, increasing cadence reduces ground reaction forces, but a lower preferred cadence does not predispose adults to experience higher ground reaction forces. Pubertal growth and motor control changes influence running mechanics, but it is… read more here.
