MEASURING METHOD AND APPARATUS FOR DETERMINING THE LENGTH CONDITIONS, THE POSITION AND/OR THE RADIUS OF MOVEMENT OF THE LOWER EXTREMITIES OF A BED-BOUND PATIENT

A measuring method determines the length conditions, the position and/or the radius of movement of the lower extremities of a bed-bound patient. A knee module of a rehabilitation mechanism is connected to a point of application of a leg of the patient. A measuring device records and determines a trajectory solely of the point of application during a movement of the leg by the knee module. A model generation device creates a kinematic model from the data. This allows a determination of the length conditions, the position and/or the radius of movement during an initializing movement without having to undertake any surgical intervention. This does away with the need for complex sensor technology and provides a kinematic model of the radius of movement of the patient, the parameters of which kinematic model are used for establishing new therapeutic procedures within the patient's physical therapy.
