The aim of this study was to investigate the benefit brought by static posturography in
the assessment of retropulsion in the elderly. For this purpose we looked for a correlation
between the average, minimum and maximum Y positions respectively in the “open eyes” and
“closed eyes” states on one hand, and BDS scores (backward disequilibrium scale) on the
other hand. We also wanted to investigate the correlation between BDS scores and CGI
(clinical global impression) scores in order to assess the capacity for evaluation of
professional experience in regards to the retropulsion of the elderly.
We have thus selected 28 patients. We evaluated them on the BDS score and on static
posturography. We then asked an experienced physiotherapist to assess the retropulsion of
some of these patients, using the CGI score. Our results do not show satisfactory correlation
between BDS scores and data from static posturography. However, it seems there is (ou there
should be – moins affirmative) a tendency to correlation between maximum “open eyes” Y
and BDS scores (p = 0.03 and [r] = 0.42). On the other hand, we have evidenced a satisfactory
correlation between BDS scores and CGI scores (p = 0.06 and [r] = 0.74).
This study suggests that static posturography is not an appropriate tool to evaluate the
retropulsion in the elderly, but does confirm the accuracy of assessment of retropulsion
through professional experience and clinical.
