1. An apparatus for monitoring the movement of a patient'"'"'s spine comprising:
- an elongated member adapted to be disposed longitudinally adjacent to the patient'"'"'s spine and further adapted to be flexible in the midsagittal plane and substantially inflexible in the frontal plane;
a first sensor mounted to the elongated member and disposed to monitor flexion and extension motion of the patient'"'"'s spine in the midsagittal plane, wherein the first sensor includes at least one strain gage; and
a second sensor mounted to the elongated member and disposed to monitor lateral motion of the patient'"'"'s spine in the frontal plane, wherein the second sensor is an optical sensor.

Abstract
An apparatus and method for detecting, monitoring, measuring and recording the motion of a patient'"'"'s spine is disclosed. The apparatus includes a vertical member attached to a belt that fits around the patient'"'"'s waist. A first sensor for detecting and monitoring flexion and extension of the patient'"'"'s spine in the midsagittal plane is mounted to the lower end of the vertical member. A second sensor for detecting and monitoring lateral bending and movement of the patient'"'"'s spine in the frontal plane is mounted to the upper end of the vertical member.
