The development of a static posture analysis instrument with direct application as an objective pre x-ray screening procedure

Abstract

The development of a relatively inexpensive device to objectively measure and allow photographic recording of a patient’s static posture and centre of gravity vector is discussed as a preliminary investigation. The overall accuracy was found to be ± 4.2° on a 360° protractor for the centre of gravity vector and an overall error of ±5.3 millimeters for measuring spinal distortion compared to x-rays. The device can be used as a pre x-ray screening instrument to: 1) determine the static biomechanics, 2) reduce the clinical need for x-ray examination or 3) suggest the specific type of x-ray required. By measuring the static posture, immediate evaluation of the effect of orthopaedic appliances on the static posture can be seen.
