1. A method of monitoring a patient under medical care, the method comprising the steps of:
- providing a sensor arrangement which is arranged to detect motion of a head, limbs and trunk of the patient, and produce a motion signal in response to the motion of a patient, andanalysing the motion signal to determine whether or not the patient is displaying signs of painfulness,wherein if the analysis of the motion signal determines that the motion includes rhythmic, repetitive motion of the head, the limbs or the trunk, a determination is made that the patient is displaying signs of painfulness.

10. A device for monitoring a patient under medical care, the device comprising a sensor arrangement which is arranged to detect motion of the head, limbs and trunk of the patient and produce a motion signal in response to the motion, and a control means which is arranged to process the motion signal and analyse the motion signal, to determine whether or not the patient is displaying signs of painfulness, the control means is arranged to determine that the patient is displaying signs of painfulness if the motion signal is determined to include rhythmic repetitive motion.
