Toward a remote assessment of walking bout and speed: application in patients with multiple sclerosis

Kamiar Aminian, Benoît Mariani, Farzin Dadashi, Arash Atrsaei

Gait speed as a powerful biomarker of mobility is mostly assessed in controlled environments, e.g. in the clinic. With wearable inertial sensors, gait speed can be estimated in an objective manner. However, most of the previous works have validated the gai ...

Drift-Free Foot Orientation Estimation in Running Using Wearable IMU

Kamiar Aminian, Frédéric Meyer, Benoît Mariani, Grégoire Millet, Mathieu Pascal Falbriard

This study aimed to introduce and validate a new method to estimate and correct the orientation drift measured from foot-worn inertial sensors. A modified strap-down integration (MSDI) was proposed to decrease the orientation drift, which, in turn, was fur ...
