Standing is one of the most important and characteristic features of human beings, indispensable for most functional tasks. Therefore, it is one of the functions usually explored in rehabilitation. There are several tests of functional valuation but none of them are quick and easy neither do they evaluate exclusively standing, fact due to which the Standing scale of the ¡°Hospital de Sagunto?(BipHS) was developed. The aim of this work is to demonstrate the reliability and validity of this scale using, as a standard the posturography analysis.
Using BipHS Scale, which takes into account 6 levels of function which are self-excluding and self-explanatory (level 0: imposible, 1: completely dependent, 2: hand-dependent, 3: free, 4: prolonged, 5: normal), we evaluated standing in 36 patients which had suffered a vascular stroke and 10 healthy individuals, using two independent observers making a analysis of agreement between both. We then registered different parameters of equilibrium using posturography and made a comparison and correlation analysis between the level of standing of our scale and the values of posturography.
The resulting kappa index was 0,83 (CI: 0,69?,97), proving a good concordance between observers. We achieved a significant association between the measures of movement of the center of pressure (cp) and the BipHS Scale, with a good linear correlation. The better the functional level, the better the balance and smaller displacement of the cp.
BipHS is a trustworthy and valid scale to evaluate standing.
