The present invention provides an alarm when a patient, supposed to remain in a specific position, changes to one which is undesirable. For example, it could be used for patients, supposed to remain recumbent, who become upright or in a position which is preparatory to becoming upright. It can be incorporated into a cuff, vest, panty, or the like, and includes energy source, alarm, on-off switch, and one or more position-sensitive sensors with interconnecting circuitry, so that the alarm is actuated whenever the patient changes to an undesirable position. An embodiment including a plurality of sensors, appropriately interconnected, avoids false alarms by permitting positions which might actuate a single sensor. The alarm can be audible, visual, tactile or other type, and can be located on the patient or at some remote location, connected directly or by wireless.
