A method and system for recording acceleration and body position data from elderly or disabled persons. The fall monitoring system includes signal feature extraction and interpretive methods for characterizing accelerations and body positions during fall events. The system can detect health and life threatening fall events in elderly persons, and can autonomously notify nursing personnel or family members that the person is in need of immediate assistance.

1. A method for monitoring a person's fall using an accelerometer included in a personal monitoring device configured to be carried on the person, having a microprocessor and a memory buffer, wherein data is stored in the buffer of the personal monitoring device, comprising the steps of:(a) sampling an output from the accelerometer indicative of body acceleration and body angle; (b) detecting whether the body angle is in a steady state indicative of a fall for at least two seconds; (c) measuring a fall duration by reading back through the buffer; (d) determining if an uncontrolled fall has taken place by testing whether the fall duration is less than a time threshold; and (e) determining whether a severe fall has occurred by comparing an angular rate of change of the body angle and an acceleration amplitude change to a severity threshold.
