Patent

CA 2555239

The invention relates to a rehabilitation device which guides a patient to perform a motion with a correct spatial trajectory, by the device applying one or more pushing, assisting, reminding, responding and/or resisting forces during a motion (or intent to move) by the patient. The forces are applied by an actuator, for example, a robotic articulated arm or a spherically jointed lever. The applied forces act as a force fields, optionally continuous, which impeded and/or guides a patient. The device can be programmable with various trajectories (paths and/or velocities) and/or forces. The forces at one point in the trajectory can vary responsive to an actual trajectory by the patient and/or responsive to a rehabilitation plan and/or improvement of the patient. The device can learn a motion entered by a physiotherapist and replay it for the patient.

L'invention concerne un dispositif de rééducation comprenant un châssis, un actionneur comprenant un mécanisme de mouvement capable d'appliquer une force qui interagit avec le mouvement d'un membre du patient à l'intérieur d'un volume d'au moins 30 cm diamètre, sur au moins trois degrés de liberté de l'actionneur, et capable d'empêcher tout mouvement notable dans un point quelconque, et une direction quelconque dudit volume. Une articulation raccordant ledit châssis audit actionneur permet de placer le mécanisme de mouvement dans un grand nombre de positions relatives différentes sur ledit châssis, de manière à produire un mouvement dudit volume par rapport au châssis.
