Abstract

In this work we investigate an approach to analyse the functional range of motion (fROM) in patients after stroke. We aim to derive an intuitive metric to describe potential changes and recovery trends in long-term rehabilitation in a day-care centre. Movement data of stroke patients were derived during free activities of daily living (ADL) and one-to-one (OTO) therapies using inertial measurement units (IMUs). Subsequent orientation estimation was used to determine upper body extremity postures of the elbow with respect to the shoulder. fROM was visualised using posture cubics, which revealed differences in body sides as well as between ADL and OTO.
