Quality framework for force plate testing.

Abstract

Following work done in C.E.C. project AIM 2002 CAMARC II, a framework of the relevant standards for testing equipment used in laboratories analysing human movement is presented. In particular, gait analysis laboratories may provide a service for a clinical team considering treatment such as surgical intervention or provision of orthoses. In this case the analysis and equipment used in the analysis must have assured quality so that the correct clinical interpretation of the results is possible. The operation of a gait analysis laboratory may be described in quality standards terminology as the operation of a 'special process'. The operation of a special process requires that particular attention be paid to procedures including confirmation of the equipment and regular testing to ensure correct operation of the equipment. In general this is difficult to achieve since equipment manufacturers still have to address this technical requirement. Although difficult, these procedures must be accomplished in the operation of a special process. Passages of the most pertinent standards are presented and a methodology of a periodic confirmation and regular spot checking of equipment suggested to ensure its correct operation. Although force plates are specifically addressed, the framework could be applied to other dynamometers and measurement equipment.
