[Determination of postural behaviour patterns in the Spanish healthy population]. / Determinación de los patrones de comportamiento postural en población sana española.

INTRODUCTION: Postural control in a standing position is externally reflected by the displacement of the centre of pressure (COP). It is necessary to determine COP movement normal patterns in order to obtain an accurate balance assessment. MATERIALS AND METHODOLOGY: A non pathological subject group was studied using NED/IBV s. v. e. evaluation equipment. Static trials based on Romberg's test were undertaken in addition to the analysis trials of voluntary postural control. RESULTS: Normal patterns have been obtained for the COP displacement and for the maximum forces produced in the anteroposterior and midlateral axes. CONCLUSIONS: COP movement comparative analysis, related to postural behaviour patterns of non-pathological persons, represents an accurate method to assess postural balance in a standing position. This information enables the design of individual and customised rehabilitation strategies in order to reduce the risk of falling.
