Abstract: A patient movement detection device is provided comprising a plurality of load cell disks, beams, or columns placed under a support member of a patient support device. The load cells are connected to a processing unit by a plurality of transmission cables. The processing unit is connected to a peripheral communication device. A method of detection of movement of a patient is provided comprising the steps of generating a signal by a load cell disk or beam when a change in a patient's center of gravity occurs on the patient support device, transmitting the signal to a processing unit, and further transmitting the signal to the peripheral communication device.
