Upper limb motion estimation from inertial measurements

ime human arm motion detector that has been developed to aid stroke patients. Two tri-axial inertial sensors are adopted to . Kinematics models then allow us to recover the coordinates of still shoulder joint. One of the significant contributions of this based optimization in smoothing the erroneous measurements ments. Comprehensive experiments demonstrate favorable tial tracking system in different sensor positions and motion of a marker-based optical motion tracker that is commercially tracking, inertial sensor, total variation. people in the UK experienced stroke and 30% of these people ween 2001 and 2002 [1]. These stroke patients needed locally nts and appropriate rehabilitative treatments after they were pital-based rehabilitation can provide the stroke patients with treatments and nursing care. However, it raises a huge demand ing human resources and equipments, etc., if the rehabilitation . f sensor and Internet technologies, researchers have worked on devices and systems equipments home-based post stroke al [3]. Rehabilitative progresses are immediately reported to ew and comment on the outcomes. Further instructions on the to the patients. On the one hand, these home-based systems f face-to-face therapy with healthcare professionals, and also On the other hand, home-based rehabilitation is more focused nd can support patients to challenge the states of depression ercises [4]. Therefore, developing home-based rehabilitation ore and more overwhelming. enable a person who has experienced a stroke to regain the ence and be as productive as before. Although a majority of ored soon after a stroke, recovery is an ongoing process.
