Using the autocorrelation function in stabilometric signal analysis

The elderly subject is moves slowly. This slowdown is a factor of instability and fall. When A fall old man perceives his fall, he reacts, but its late. Measuring the slowing down of the old man is therefore of obvious clinical interest and there are already techniques for measuring this slowing down, such as the speed of walking, for example. The technique we present is new and more general, it measures something that seems more appropriate and in relation to the reaction time of the postural system.
