1. A body movement sensing apparatus comprising:
- a thin, flexible, resilient pad;
a layer of adhesive on one surface of the pad for releasably attaching the pad to a human body;
at least one flexible movement sensor embedded in the pad for flexing with the pad when an area of the body moves beneath the pad;
a source of electrical power connected to the at least one sensor for powering the sensor; and
an indicator connected to the at least one sensor for providing an indication of movement of the area of the body exceeding a predetermined limit.

Abstract
A body movement sensing apparatus includes a thin, flexible resilient pad with a layer of adhesive on one surface thereof for attaching the pad to a human body. At least one flexible motion sensor such as a Wheatstone bridge in the pad flexes with the pad when there is movement of an area of the body beneath the pad. The sensor is connected to an indicator for providing an audible or visible indication of body movement exceeding a predetermined limit. The sensor can also be a spring metal or other strip which makes a noise when flexed.
