Abstract
A position sensing system comprises a position sensor having an accelerometer and a gyroscope, an alarm, and a controller configured to receive data from the position sensor and activate the alarm according to alarm management instructions stored in a memory. In some embodiments, the alarm instructions include a snooze option to allow the user/patient to temporarily deactivate the alarm. The controller is communicably linked to a remote display device configured to display the orientation of the user's body part.
